1. INTRODUCTION

1.1 Document Overview

The following outlines the content of Remote Control Locomotive (RCL) Operations Manual:

• Introduction – Describes the purpose and physical description (Chapter 1).

• Controls and Indicators – Lists and describes the controls and indicators (Chapter 2).

• Operation – Provides guidelines for operation as well as information on the various

modes used (Chapter 3).

• System Faults – Lists the system faults and actions (Appendix A)

This manual refers to the operator as the user of the RCL system; however, the term operator and you are used interchangeably when outlining procedures or instructions.

1.2 Purpose of Equipment

The Remote Control Locomotive (RCL) system provides railroad yard crews the ability to control one locomotive at a time through an Operator Control Unit (OCU) for switching and general yard operations. The locomotive under control can be used in Multiple Unit (MU) locomotive consists. The system provides control of the locomotive by command signals transmitted over a radio link from the OCU. Operationally, several trains equipped with the RCL system can operate on the same radio frequency and within radio range of one another. Additionally, the RCL system allows two OCUs to operate the train in a pitch and catch method where only one OCU is in control of the train. The RCL system consists of the portable OCU and a Locomotive Control Unit (LCU) located on the locomotive and other support components. The support components are such items as an operator vest for the OCU, an electronic fence for hump yard operations, and various safety and operational attachments to the locomotive.

1.3 Physical Description of Equipment

The RCL system consists of On-board locomotive equipment and Off-board Operator equipment. The Off-board equipment functions as the commanding unit and the On-board equipment functions as the locomotive controlling unit (Figure 1.3-1).

The locomotive equipment is mechanically designed to withstand, the shock and vibration encountered in locomotive operation. The system is sealed against dust, locomotive gasses and oily fumes; however, it is not weatherproofed and must be sheltered from the elements. The Operator Control Unit (OCU) is designed to meet NEMA 4 standards and to withstand the rigors encountered in the railroad environment, however, the OCU is not waterproof and must be sheltered from the elements.

1.4 Operational Overview

In conventional railroad yard switching operations without an RCL system, all car and locomotive movements require an operator on board the locomotive as well as personnel on the ground to direct movements and set switches.

The RCL system provides the yard crews with the ability to control the locomotive from a portable/handheld unit, thereby eliminating the need for an operator on board the locomotive. The yard crew can then set switches and directly control the locomotive/train movements from the ground. Additionally, the RCL system allows one operator to transfer control to another operator in a pitch and catch method when control of the train is needed from another position in the yard.

The yard crew uses the portable OCU to command locomotive movement. The OCU also provides the operator the ability to control the direction, speed, and braking of the locomotive/train. Additionally, the OCU provides the capability to control the headlights, manual sand, bell, and horn. The OCU provides fault and alarm status data from the locomotive.

The LCU on board the locomotive receives the commands from the OCU and activates the appropriate control functions. Control relays or solenoid valves control each function on the locomotive. Sensor circuits monitor the status of the controlled functions to ensure that the control function has been properly activated. If the status does not match the commanded function, a miscompare alarm is generated and appropriate action is taken to ensure the locomotive is in a safe and appropriate state.

If communications are lost between the OCU and LCU for greater than 5 seconds the LCU will go to the Park state where the locomotive is idled and a full service automatic and independent brake application is made. The system remains linked and if communications are restored the Park State can be recovered and normal operations resumed. If communications is lost for longer than the comm. loss unlink time as set in the Configuration File, the LCU will go to the Safe State where the emergency brakes are applied, the locomotive is set to idle, and the system is unlinked.

1.5 OCU Commanded Functions

The OCU detects the operator inputs and transmits these commands to the LCU. The LCU then activates the appropriate control signals to carry out the commanded control function. Table 1.5-1 lists the normal command functions transmitted to the LCU.

1.6 LCU Control and Status Functions

When the LCU receives commands from the OCU, it activates the appropriate locomotive control lines needed to perform the commanded control function. Locomotive status lines are monitored to ensure that the proper functions have been activated and to provide feedback for function control loops. Table 1.6-1 and Table 1.6-2 lists the normal LCU controlled and monitored functions.

3. INTRODUCTION

This chapter provides recommended guidelines for operating the RCL system and includes additional information to assist the operator in understanding the various modes of operation.

The procedures are written to assist the railroad in establishing safe operating procedures for the RCL System; however, they are not intended to replace standard locomotive operating procedures or approved railroad practices. Standard railroad operating procedures should take precedence.

A periodic checkout of the RCL system is recommended. This checkout should include a complete test of all system functions as well as checks of the radios. For detailed circuit descriptions, see the Service Manual.

3.1 Operator Interface Overview

The Operator Control Unit (OCU) is the primary operator interface. The OCU operation begins at RCL system linking and progresses through the required tests until the operator has complete control of the RCL locomotive.

3.2 Initial Conditions

The following conditions are required prior to RCL start-up and operation:

1. The RCL System is installed and operating properly.

2. The operator is completely familiar with locomotive operating procedures and established railroad practices and is duly authorized by the railroad to operate an RCL equipped train.

3. All RCL power switches and circuit breakers in the RCL locomotive are in the OFF position.

Note – If the locomotive is in Manual Mode all the RCL switches and circuit breakers will be on.

4. The operator puts fresh batteries in the OCU and verifies battery charge.

5. The operator puts on the operator vest and adjusts for comfort.

3.3 Preparing RCL Equipment for Service

Preparation of the RCL equipment is done in steps as indicated in the following sections. Note – Locomotive Independent brakes (cabstand) should not be released until after the

RCL system is setup.

3.3.1 Locomotive Set Up for RCL Operation

Set the following switches on the RCL locomotive to the positions indicated.

Note – All units which form the part of the RCL consist must be coupled to the RCL equipped unit in the conventional trailing unit mode.

Set the RCL System switches to the position indicated:

1. RCL Manual/RemoteValve –Remote position

Note –When RCL Manual/Remote valve is placed in the Remote position, the locomotive will go to emergency.

2. RCL main Circuit Breaker -ON

3. SCU Relay Circuit Breaker -ON

After system initialization the RCL SCU unit turns on the following LED status indicators: LCU/SCU Power (green), Train line Relay Power (green), and Event Recorder Continuous Self-Test (green). The SCU displays “Low MR” until the Main Reservoir pressure is greater than 80 psi. The SCU then displays the “Setup Emergency” message.

After system initialization the RCL LCU unit enters the Setup State where it will wait for link commands from the OCU. While in the Setup State the LCU will be in the Safe mode in which the emergency brakes are applied, the Independent Brakes are set to full, and the Throttle is set to Idle.

If the LCU is not linked to an OCU within 90 seconds then the LCU enters the Standby Mode. In this mode, the LCU remains powered up but relinquishes control of the locomotive air brakes and allows the locomotive to be operated conventionally. When the LCU enters the Manual mode (after 90 seconds) the emergency valves are closed which allows manual recovery of the train brake pipe using the automatic brake handle. When the brake pipe is recovered and the brake pipe pressure rises above 65 psi, then the LCU releases the Independent brakes and turns control over to the locomotive operator. When the LCU receives a link command from an OCU it will then re-enter the Setup State.

3.3.2 Operator Control Unit Setup

Set the following switches on the OCU to the positions indicated:

Table 3.3.2-1 OCU Switch Setup

Switch Position

Speed Selector (SS) STOP Reverser Selector (RS N Independent Brake Selector (IBS) EMERGENCY Bell / Horn Selector (BHS) OFF Power (PWR) ON

3.3.3 RCL Equipment Shutdown Procedure

The following procedure should be followed to shutdown the RCL system:

1. With the train stopped; set the Speed Selector to STOP, the Reverser to the Neutral (N) position, The Bell and Horn Selector (BHS) to OFF, and the independent brake to FULL or Emergency.

2. Unlink the system by setting the PWR switch on the Primary OCU to the OFF position (press and hold pwr for 5 seconds). Follow the directions on the OCU display to power down OCU. The OCU transmits the Unlink command to the LCU and after receiving an acknowledge command from the LCU that it is the Safe mode, and then powers off.

3. When the RCL system on the locomotive receives the unlink command from the Primary OCU, it enters the Setup State and initiates an Emergency Brake Application, sets a Full Independent Brake Application, sets the Throttle to idle and enters the Safe mode. The LCU then transmits an acknowledge command to the OCU indicating that it is in the Safe mode.

4. After 90 seconds the LCU enters the Manual Mode, closes the emergency valves, and allows the locomotive operator to operate the locomotive conventionally.

The locomotive can now be operated conventionally without having to power off the LCU, cutout any pneumatic valves, or re-configure any switch settings. Alternatively, the LCU can be powered off and cutout as follows:

1. Place the RCL Main Circuit Breaker to OFF.

2. Move the RCL Manual/Remote Valve to the Manual position.

3. Configure the locomotive for conventional lead operation.

3.4 System Linking and Testing

When the train has been made up properly and the RCL system has been prepared per the previous instructions, system linking and safety checks can be performed. On initial power up, the OCU performs a display and audible alarm test. All display indicators light in sequence, each line of the display is exercised, and the audible alarm sounds. When all

GE Transportation Systems Global Signaling, LLC Proprietary and Confidential

3-3

Document No. 5002866 Rev. C (DRAFT)

28 April 2003

indicators and the audible alarm have been verified, the display shows GETS GS LOCOTROL RCL, and the OCU is now ready for linking to the Setup Control Unit (SCU). If the locomotive is not set up properly for RCL operation (i.e., Air brake cutout cock not cut in, Locomotive trucks cutout, automatic brake handle not in release, etc.) or an alarm condition exists on the locomotive, the SCU display will indicate which device that is improperly setup or the RCL fault that is active. If properly set up, the SCU will indicate Setup Emergency when the LCU is in the Setup State or Manual Mode when it is in the Manual mode and is ready for linking with the OCU.

3.4.1 Linking RCL Operation

To begin the RCL linking process, follow the guidelines outlined below:

1. Hold the OCU so that its Infrared Port is pointed at the SCU Infrared port and press and release the PCC/Link button on the OCU. (see Figure 3.4.1-1) The OCU will give a Linking LCU and Radio Testing message.

2. Verify that the OCU and the SCU are linked together by observing that the OCU displays Linked to Locomotive, Loco ID: XXXX and that the Green OCU # 1 Linked status LED is lit. The first OCU that links to the SCU is defined as the Primary OCU and the Controlling OCU LED illuminates on the OCU to indicate that it is the controlling OCU for the RCL system.

3. Once linked, the SCU will display Primary Tilt Test Not Complete. Press and hold the tilt override switch forward. Rotate the OCU greater than 45 degrees from horizontal until the SCU message disappears. The locomotive voice Radio will send a voice message that the tilt test is completed and the locomotive number. The RCL system remains in the Setup State (or transitions to the Setup State if it was in the Manual mode) with the emergency brakes applied, the Independent Brakes set to Full, and the Throttle in Idle. Release independent brakes on cabstand.

4. Leave the locomotive and proceed to the area of intended operation.

Figure 3.4.1-1 Linking

A secondary OCU can be linked to the LCU for use during Pitch and Catch operations. Linking the secondary OCU is accomplished in the same manner as the Primary OCU except the Primary OCU must acknowledge and authorize the secondary OCU linking.

The process for linking the secondary OCU is outlined below:

1. Hold the second OCU so that its Infrared Port is pointed at the SCU Infrared port and press and release the PCC/Link button on the OCU. The Primary OCU operator will get a Secondary OCU Link message on their display and within 5 seconds the operator must press the LR or RR button on the OCU to authorize the second OCU to Link.

2. Verify that the second OCU and the SCU are linked by observing the Locomotive road number on the second OCU display and that the Green OCU # 2 Linked status LED is lit. The Controlling OCU LED on the secondary OCU remains off.

3. If the Setup Emergency has been recovered by the Primary OCU, the locomotive will be put into Park State. Once the secondary OCU is linked a secondary OCU Tilt test must be performed using the same method as the primary Tilt test. If the Setup Emergency has not been recovered prior to linking a secondary OCU, the RCL system will remain in the Setup State.

3.4.2 Emergency Valve Test

The Emergency Valve Test verifies the proper operation of the RCL locomotive emergency. The test runs automatically when the automatic brakes are released for the first time after linking.

The operator moves the Independent Brake Selector (IBS) from the EMERGENCY position to the RELEASE position. The SCU will display EMV Test in Progress. The

GE Transportation Systems Global Signaling, LLC Proprietary and Confidential

3-5

Document No. 5002866 Rev. C (DRAFT)

28 April 2003

OCU will display Consist Recovering and if the test passes, BP will recover and the OCU will display Consist Ready.

Upon successful completion of the Link operation, recovery of the Set Up Emergency, and verifying the emergency valves, the Locomotive Control Unit (LCU) transitions into the Ready State. The Ry State allows an OCU operator to control the locomotive’s speed and brakes. The SCU display Remote Mode on the display.

3.4.3 System Status Functions

The RCL system status is displayed on the OCU display. Select the status functions using the TOR actuator. By toggling the TOR actuator toward the Status position, the OCU display toggles through the each status function. As the operator selects each status function, the OCU scrolls through the information related to the selected item. The selected status functions and information provided is as follows:

3.4.4 System Operating States

The following sections identify and describe the main operating States of the RCL system and the criteria used to transition between states.

3.4.4.1 Initialization (Power Up) State

Upon power up the LCU performs a power up self-test and checks the status of the locomotive, brake, and yard containment.

If the self-test passes, the LCU system transitions to the Setup State. Failure of the self-test holds the system in the Initialization State and an alarm message is displayed on the SCU display.

3.4.4.2 Setup State

In the Setup State, the LCU commands the air brake system to emergency, the independent brakes to maximum, and the locomotive to Idles with direction Neutral. The SCU display shows Setup Emergency. The LCU also checks for system faults, improper system setup, and invalid configuration parameters.

If the LCU system checks pass then the LCU can be linked to the OCU. Failure of the system checks holds the system in the Setup State, displays an alarm message on the SCU display, and prevents the LCU from Linking with the OCU.

3.4.4.3 Manual Mode

If the LCU remains in the Setup State for 90 seconds without linking to an OCU, then the LCU transitions to the Manual Mode. When the LCU transitions to the Standby Mode, the SCU display shows Manual Mode. The locomotive is still in emergency with the LCU maintaining a Maximum (Full) independent brake application. The brake pipe may now be recovered manually using the automatic brake handle on the cabstand. When the brake pipe pressure rises above 65 psi, the LCU releases the independent brakes and the locomotive is now suspended from RCL operation and can be operated conventionally.

The LCU remains in the Manual Mode until a Link command is received from an OCU via the Infra – Red port. When a Link command is received, the LCU re-enters the Setup State, applies the emergency brakes, sets the independent brakes to maximum (Full). The LCU then processes the linking commands from the Setup State as outlined above.

3.4.4.4 Ready State

Upon successful completion of the Linking sequence with the OCU, recovery of the Setup emergency, and verification of the emergency valves, the LCU transitions to the Ready State. The Ready State is the system operational State and allows the operator to control the following:

• Locomotive Speed

• Independent Brakes

• Automatic Brakes

• Bell

GE Transportation Systems Global Signaling, LLC Proprietary and Confidential

3-7

Document No. 5002866 Rev. C (DRAFT)

28 April 2003

• Headlights

• Horn

• Sand

The system monitors the yard containment to ensure that the system is operating safely within the proper boundaries.

The system also monitors all critical parameters and subsystems to ensure no fault conditions are present. If fault conditions are detected, the system transitions to either the Park State or the Safe State, depending on the severity of the fault.

The System returns to the Setup State if it receives an Unlink command from the controlling OCU or if it unlinks automatically due to an extended loss of OCU communications.

3.4.4.5 Park State

When a minor fault is detected, the system enters the Park State. Minor faults result from situations where the locomotive should be stopped until the fault is resolved, but does not warrant an emergency brake application.

Minor faults result in the following:

• Full Service Automatic Brake Application

• Full Independent Brake application

• Direction Neutral

• Throttle Idle

The system will remain in the Park State until:

• The Fault is Cleared

• The locomotive has stopped

• Primary operator acknowledges the fault by moving the Speed Selector to the STOP

position and the IBS to the FULL position as prompted by the OCU.

3.4.4.6 Safe State

The system enters the Safe State when a Major Fault is detected. Major Faults result from a situation where the locomotive needs to be stopped using an emergency brake application.

For Major Faults, the system commands the locomotive to a Safe State which consists of:

• Emergency Brake Application

• Full Independent Brake Application

• Direction Neutral

• Throttle Idle

The system will hold the locomotive in the Safe State until:

GE Transportation Systems Global Signaling, LLC Proprietary and Confidential

3-8

Document No. 5002866 Rev. C (DRAFT)

28 April 2003

• The Fault has been cleared

• A 60 second Emergency Brake timer has elapsed. (The OCU display shows a 60

seconds count down timer when the IBS is placed in the Emergency position to indicate the time remaining).

• The operator acknowledges the fault by moving the SS actuator to the STOP position

and the IBS actuator to the EMERGENCY position as prompted by the OCU.

• The Operator moves the IBS actuator from the EMERGENCY position to the

RELEASE position.

3.5 Control Functions

3.5.1 Air Brake Functions

The LCU provides all air brake control of the locomotive and train brake functions including Multiple Unit (MU) capability and emergency brake control. The brake system is operated with the Brake Valve always cut in to ensure operation is allowed only when automatic braking capability is available.

3.5.1.1 Automatic Brake

Automatic brake applications can be initiated by the operator using the OCU ABS switch as follows:

1. Push the ABS switch away from operator and then release to increase brake application one level

2. REL is 0 psi reduction

• MIN is 7psi reduction

• LIGHT is 15 psi reduction

• MED is 20 psi reduction

• FULL is full service reduction

3. The solid LED on the indicator shows switch position and the flashing LED shows current brake level on the locomotive.

4. Operator releases brake application by pulling back on the ABS for 2 seconds.

Note: Automatic brakes are bailed for an automatic brake applications except full and emergency.

3.5.1.2 Charge

Charge will recharge locomotive brake pipe and release automatic brakes. To initiate charge:

1. Press LR or RR on the OCU and move ABS immediately from FULL to CHARGE position.

2. From REL pull back for 5 seconds on TBA to wrap it back to CHARGE.

GE Transportation Systems Global Signaling, LLC Proprietary and Confidential

3-9

Document No. 5002866 Rev. C (DRAFT)

28 April 2003

To release from charge pull back of ABS momentarily. Note: i) Locomotive is not allowed to move while in charge.

ii)If MR is less than 110 psi the RCL system will “dry charge” the locomotive by setting throttle to Notch 4 (Direction is Neutral).

3.5.1.3 Independent Brakes

The locomotive independent brake functions are controlled manually by the operator via the Operator control Unit (OCU) or automatically (during speed control operation) by the LCU.

The operator initiates independent brake applications by rotating the independent brake control on the left side of the OCU. The operator can select the following independent brake setting as shown in Table 3.5.1.3-1 by moving the independent brake controller to the appropriate position.

Table 3.5.1.3-1 IBS Brake Cylinder Pressure

IBS Setting Brake Cylinder Pressure

REL 0 psi LOW 25 psi MED 45 psi FULL > 65 psi

Note: The locomotive brake cylinder pressure is determined by the J type relay valve installed on the locomotive and the actual brake cylinder pressure may vary from those noted above in Table 3.5.1.3-1. See Table 3.5.1.3-2 below.

Table 3.5.1.3-2 Various J Type Relay Valve Brake Cylinder Pressures

J Type Valve Brake Cylinder Pressure

J8.6 38 psi J1 45 psi J1.6 72 psi

The LCU will automatically apply independent brakes as needed to control the train speed. An automatic Bail feature is provided in the RCL system to release the locomotive brakes

after any automatic brake application. When the LCU commands an automatic brake application less than Full Service, the BAIL function will be activated for 20 seconds. The locomotive brakes are not bailed during Full Service Applications. During emergency brake applications and locomotive penalty applications the locomotive brakes will not be bailed.

3.5.1.4 Emergency Brakes

An emergency brake application can be initiated by the operator in any of 3 methods:

GE Transportation Systems Global Signaling, LLC Proprietary and Confidential

3-10

Document No. 5002866 Rev. C (DRAFT)

28 April 2003

a) Rotate the IBS actuator to the EMER position on either the Primary or Secondary

OCU. This causes an emergency brake command to be sent to the LCU on the locomotive which puts the train in to emergency.

b) Cause a brake pipe emergency at the locomotive cabstand by moving the automatic

brake handle to emergency or opening the conductor’s emergency valve.

c) Press one of the RCL Emergency STOP switches located in the locomotive cab or

on the left or right side of the locomotive.

When an emergency brake application is in effect, the locomotive is placed in the Safe State where the emergency brakes are applied, Independent brakes are set to full, Bail is deactivated, and the throttle is idled.

When an Emergency Application is commanded the OCU will display Emerg.Countdown:XX. This is a 60 second count down timer, which indicates when the Emergency application can be reset.

An operator initiated emergency brake application is released by disengaging the locomotive emergency stop switches or brake valves (if previously activated), setting the OCU speed selector to the STOP position, the independent brake selector to the EMER position, waiting for the emergency timer to expire (1 minute), then rotating the IBS actuator to the REL position. The OCU will prompt the operator throughout this recovery process.

3.5.2 Air Brake Function Interlocks

To ensure the RCL system operates in a Safe State, interlocks are provided in the air brake control system to protect against improper operation.

1. Brake Valve CUT IN – The locomotive Brake Valve must always remain in the Cut IN position (except Emergency). Detection of the Brake Valve out will put the train in the Safe State.

2. Automatic Brake Handle in Release – The locomotive brake handle must always be placed in the RELEASE position. Movement of the Automatic Brake handle out of the RELEASE position will result in the locomotive being commanded to the Park State. The OCU will display BV Handle not in Release.

3. Low Main Reservoir – If the Main Reservoir pressure drops below 105 psi for greater than 5 Seconds, a Low Main Reservoir Warning alarm will be generated. If the Main Reservoir pressure drops below 90 psi for greater than 5 Seconds, a Low Main Reservoir Fault will be declared and the locomotive will be commanded to the Safe State. While the RCL system is in the Charge mode, the Low Main Reservoir feature is disabled.

4. Brake Pipe not Charged – If the train brake pipe is not properly charged, the locomotive will be prohibited from releasing the independent brakes. The brake pipe is considered charged if the rate of change of airflow into the brake pipe is less than 5 cfm per second.

GE Transportation Systems Global Signaling, LLC Proprietary and Confidential

3-11

Document No. 5002866 Rev. C (DRAFT)

28 April 2003

5. Low Brake Pipe – If the brake pipe pressure drops below 45 psi, the locomotive will be commanded to a Safe State. If the direction is neutral and the brake cylinder pressure is greater than 25 psi this interlock will be disabled.

6. Brake Pipe Rise – The LCU system continually monitors the brake pipe pressure during all automatic brake applications. If brake pipe pressure increases significantly (2 psi sustained for 2 seconds) when not expected, an emergency brake application is applied and the system commanded to the Safe State.

7. Train Separation Detection – A train separation causes a charged brake pipe to fall at an emergency rate. If the brake valve cuts out with an un-commanded drop in brake pipe pressure, the LCU will declare a train separation and command the locomotive to the Safe State.

8. Brake Cylinder Pressure Monitoring – The brake cylinder pressure is monitored at each truck to ensure that each truck has been properly cut in and that the cylinder pressure is rises to at least 25 psi when the commanded independent brake control pressure is greater than or equal to 25 psi. If the monitored brake cylinder pressure does not rise greater than 25 psi the locomotive will be commanded to the Park State.

3.5.3 Electrical Functions

The LCU provides all electrical control of the locomotive including MU capability. Control relays provide the required signals for proper locomotive operation and safety equipment operation. In addition monitoring circuits are provided to ensure safe and effective operations.

3.5.3.1 Direction Control

The LCU controls the locomotive direction as defined by the operator using the Reverser Selector on the OCU. The Speed Selector (SS) must be in the STOP position with actual speed at 0 m.p.h. in order to select a direction with the Reverser.

Once a direction is selected and the speed selector is set for speed control operation, movement of the Reverser Selector back to the neutral (N) position returns the locomotive throttle back to the idle and sets the direction to neutral. No brake application is applied. The locomotive remains in this state until:

1. The operator moves the OCU Reverser Selector (RS) to the previously commanded direction. The locomotive then resumes speed control operation at the OCU commanded speed setting.

2. The operator moves the SS actuator to the STOP position. The LCU commands the locomotive to stop.

3.5.3.2 Throttle Control

The RCL system does not provide the operator direct throttle step control; rather, the operator uses the OCU to select the desired operating speed. The LCU also provides MU capability for controlling the tractive effort on all locomotives within the consist.

The RCL system provides a speed control system for controlling traction and moving the locomotive and train. Provisions are made within the speed control algorithms for operation at Hump yards and Flat yards.

3.5.3.3.1 Throttle vs Excitation Speed Mode

Before linking the OCU, the SCU inside the locomotive can be set to excitation or throttle mode. On the SCU press MENU, scroll down to the Speed Control option. Press enter and use arrow key to pick Exciationt or Throttle and press ENTER again.

Throttle mode must be used if another locomotive is MU’d that does not have slow speed control. Excitation uses the excitation Trainline and will provide a smoother speed control.

To enter the Speed mode and move the train, the operator uses the OCU to perform the following steps:

1. Set the SS actuator to the STOP position.

2. Select the desired movement direction using the Reverser Selector.

Press the LR or RR button and, within 3 seconds, move the speed selector to the desired speed control position. Speed settings are configurable and may vary from yard to yard. The typical speed settings for Flat Yards (Table 3.5.3.3.1-1) and Hump Yards (Table 3.5.3.3.1-

2) are defined as:

The LCU receives commands from the OCU and releases the locomotive brakes, sets the commanded direction, and enters the Speed Control mode. The LCU rings the Bell for 3 seconds and then the LCU increases the throttle and generator excitation until the train starts moving. The throttle and excitation are then continually adjusted, as required, to maintain the commanded speed.

The operator may increase or decrease the set speed using the SS on the OCU. The LCU will then increase / decrease throttle and excitation as required to adjust the speed for the new command speed.

If the speed increases above the point where decreasing the throttle and excitation cannot reduce the speed, then the LCU will automatically apply independent brakes.

While in Speed Control mode if the commanded brake application exceeds the predefined limit or the speed limit is exceeded with excessive independent or automatic brake application, the LCU will declare a Drag Brake Warning and alert the operator via the OCU alarm display.

To exit Speed Control mode, the operator moves the Speed Selector (SS) to the STOP position on the OCU. Upon receipt of the STOP command the LCU speed control will set the command speed to zero m.p.h. set the throttle to idle, and set the locomotive brake to full.

3.5.3.4 Headlight Control

The LCU automatically controls the locomotive headlights based on the OCU commanded brightness level and the direction of movement of the locomotive. The default setting for the headlights upon linking is DIM.

The operator momentarily presses and releases the Manual Headlight (MHL) switch on the OCU to change the locomotive headlights to OFF, DIM, or BRIGHT. Each time the operator presses the MHL button the intensity will step to the next level of intensity and then wrap around back to OFF. The locomotive front and rear headlights will be controlled in intensity as shown in Table 3.5.3.4-1:

3.5.3.5 Horn / Bell Control

The RCL system provides control of the locomotive bell and horn. The Bell and Horn can manually be controlled by using the OCU. In addition, the LCU automatically activates the Bell when commanded by AEI Tags.

When the locomotive enters Speed mode the LCU automatically activates the locomotive Bell for 3 seconds before the locomotive is moved.

The locomotive bell can be activated by moving the Bell and Horn Switch (BHS) to the BELL position on the OCU. The BELL status indicator illuminates as long as the bell is active on the locomotive. To de-activate the bell, the operator returns the BHS to the OFF position.

With the BHS in the BELL position, the operator activates the locomotive horn by moving the BHS to the HORN/ BELL position on the OCU. The LCU keeps both the locomotive bell and horn activated as long as the BHA is in the HORN/ BELL position. The BELL/HORN status indicator illuminates as long as the bell and horn are active on the locomotive. Releasing the BHS returns it to the BELL position and the LCU will continue to keep the locomotive bell activated. The bell and horn can be activated by either the Primary or Secondary OCU.

3.5.3.6 Sand Control

The OCU provides the operator with the capability to activate the manual sanders on the locomotives. If the LR or RR actuator is pressed and held for 5 seconds or more, the OCU will send a sand command to the LCU. When the LCU receives the sand command it activates the locomotive sanders in the direction of travel (or the last selected direction) for 30 seconds. Each additional press and hold of the LR or RR actuator for 5 seconds resets the LCU sand timer to 30 seconds.

The OCU display will momentarily indicate manual sanding is active. The OCU will also display Sustained Wheel Slip when the wheel slip trainline is active 5

at least 5 seconds, as an indication that the operator may want to apply the manual sanders.

3.5.3.7 Electrical Function Interlocks

To ensure the RCL system operates safely, interlocks are provided to prevent improper and invalid operation. A complete fault list is provided in Appendix A.

1. The LCU will command the locomotive to the Park State if the PC train line is activated.

2. The LCU will command the locomotive to the Park State if the locomotive speed exceeds the set speed by 13 m.p.h. for 5 seconds.

3. The LCU will command the locomotive to the Park State if the locomotive speed does not increase above 0 m.p.h. within 15 seconds of commanding speed.

4. For Speed operation one and only one direction must be sensed at the LCU. If the proper direction is not detected the LCU puts the locomotive in the Park State.

5. Emergency brake applications force the locomotive immediately to Idle.

6. During Speed Control operation, only valid throttle steps are allowed. Invalid throttle steps detected by the LCU puts the locomotive in the Park State.

7. Loss of communications between the LCU and the SCU causes the LCU to put the locomotive in the Park State.

3.6 Special Operating Features

The RCL system provides special features to aid and enhance operational effectiveness.

3.6.1 Pitch and Catch

The OCU allows the primary operator to transfer (Pitch) control of the locomotive to one other previously linked operator (Catch). The RCL locomotive must be stopped with at least 25 psi brake cylinder pressure and not in Emergency for control to be pitched.

To transfer control of the LCU from one operator to another using the Pitch and Catch function, both operators must be linked to the same LCU. The 2 operators then use their respective OCUs to perform the following steps:

1. The primary operator (A) stops the locomotive and sets the independent brakes with a brake cylinder pressure greater than 25 psi.

2. The primary operator (A) requests a Pitch operation by pressing the PCC/LNK button on their OCU. (if the Primary operator does not receive catch confirmation from the secondary operator within 10 seconds, the audible alarm sounds and a PITCH FAILED message is displayed. The primary OCU (A) remains in control of the LCU.)

3. The Secondary operator (B) receives an audible signal and a Catch request on the OCU display. The secondary operator (B) then presses the PCC/LNK buttonon the OCU to accept the catch. (if the secondary operator does not receive catch confirmation from the primary operator within 10 seconds, the audible alarm sounds and a PITCH FAILED message is displayed. The primary OCU (A) remains in control of the LCU.)

4. The primary operator (A) receives an audible signal and a Catcher Ready on the OCU display. The Primary operator (A) again presses the PCC actuator on the OCU to confirm the pitch.

5. The LCU then reassigns the primary operator as B and the secondary operator as A. The primary operator will have its Controlling OCU LED on.

6. The Automatic Brake settings and Headlight control settings are automatically transferred to the new Primary OCU when the pitch and catch is successfully completed.

3.6.2 Sleep Mode

The Primary or Secondary OCU can go into Sleep mode. Sleep mode leaves the RCL system linked and puts the locomotive into Safe State (only for primary OCU going into Sleep mode) for up to 90 minutes. After 90 minutes, the system will automatically unlink and go into Standby mode after 90 additional seconds.

Document No. 5002866 Rev. C (DRAFT)

28 April 2003

To put the system into Sleep mode, power down the primary and/or secondary OCU and follow the directions on the OCU for entering Sleep mode. The OCU will confirm Sleep mode before shutting down and the OCU #1 (#2) linked LED will flash on the SCU.

To go back to RCL mode, power on the OCU using the PWR button within 90 minutes from going into Sleep mode. The OCU will display the locomotive number it is linked to and resume RCL operations as long as it was in communication range.

If a third OCU links up to the RCL system while the other OCU’s are asleep, the new OCU will be the primary and the other OCU’s will automatically be unlinked.

3.6.3 Yard Containment

The RCL system provides methods to detect specified yard boundaries, stop locomotive movement automatically when boundary limits are exceeded, and restrict locomotive speed on specific yard tracks and pullback tracks. Two independent methods are used (Figure

3.3.3-1) for yard containment: Automatic Equipment Identification (AEI) tag readers and Global Positioning System (GPS).

Figure 3.6.3-1 Yard Containment

3.6.4 AEI Tag Reader

The AEI tags are used to enforce yard containment, set temporary speed restrictions for various segments of tracks, activate pullback control of the locomotive for hump yard operations, provide warning of movement out of an operational area, and sound the horn and/or bell automatically.

3.6.4.1 Yard Containment

Yard containment tags are used to limit the RCL controlled locomotive from leaving the yard.

There are two types of yard containment tags. The first type is the Containment Warning Tags, which provide a warning to the OCU operator that the yard limit is about to be exceeded. It does not restrict the speed or stop the locomotive. These are mounted on the inside of the second type, which are the Containment Violation Tags. These are the actual

GE Transportation Systems Global Signaling, LLC Proprietary and Confidential

3-17

Document No. 5002866 Rev. C (DRAFT)

28 April 2003

yard containment tags, which will cause the LCU to bring the locomotive to a stop (Park State) and applying a Full service independent and automatic brake application.

3.6.4.2 Speed Restrictions

Speed Restriction tags can be used to restrict the speed of the locomotive through sections of track. This allows the yard personnel to set speed restrictions. The LCU will restrict the OCU commanded speed when these tags are read (if they are more restrictive). When Speed restrictions are in force, the operator will be notified by a Speed Restriction message on the OCU display.

3.6.4.3 Pullback Control

Pullback control limits the speed of the locomotive as it moves back on the pullback track (Figure 3.6.4.3-1).

The following outlines the Pullback control operation:

1. Set the speed on the OCU for the locomotive to travel down the pullback track.

2. As the RCL locomotive enters the pullback area, it crosses the Start Pullback Tag. You will receive confirmation on the OCU display, Pullback On: GPS OK.

3. The AEI tags will then limit the speed of the locomotive as it moves back on the track.

4. The operator can further limit the speed of the locomotive if needed.

5. When the end of the Pullback track is reached, the locomotive crosses the End of

Pullback Tag and the locomotive stops. The operator will now receive an End of Pullback Track message on the OCU display.

6. Change the locomotive direction and command speed.

7. The RCL system then disables Pullback Control and notifies the operator by removing the Pullback On: GPS OK message from the OCU display.

8. The OCU operator controls the locomotive back down the Pullback track in the opposite direction. As the locomotive moves towards the hump yard under operator control, the AEI tags do not limit speed.

9. When pullback control is disabled and the locomotive is moving out of the pullback track, if a Tag has not been crossed, then anytime the direction of travel changes back to the direction when it was enabled, the pullback control re-enables itself. After the locomotive crosses a tag, then the Pullback function remains disabled until the locomotive crosses another tag while traveling into the Pull Back track direction.

Figure 3.6.4.3-1 Pullback Control

3.6.4.4 Bell and Horn

Bell and Horn tags can be used to automatically sound that the horn or bell. These tags are placed at crossings in the yard, or in places where they are normally sounded.

3.6.5 GPS

The Global Positioning System (GPS) containment system provides a backup to the AEI tag system. Whenever the GPS system determines that the locomotive has entered a particular region (either yard limit area or pullback protection area), and no tags are seen within a set distance, it sends the appropriate message to the OCU and/or stops the train.

There are two types of GPS containment which are for keep-out areas within a yard and leaving a yard. When the GPS detects that the locomotive is out of the yard, the LCU will command the locomotive to come to a stop and wait for the operator to acknowledge the violation. The operator may have to board the locomotive (or optionally use the OCU) to acknowledge the fault and continue operation in the same direction. Movement, however, in the opposite direction of travel will be allowed and the GPS system waits until the locomotive re-enters the yard limits before re-arming the GPS again. This allows the operator to stop only once for a given containment violation.

The second type of GPS containment is for entering the pullback protection area. If the GPS indicates that the locomotive is in a pullback protection area and a pullback control tag has not been seen, a GPS pullback fault is declared and the locomotive is stopped. Movement in the opposite direction of travel is allowed after acknowledging the fault in the Park State.

If GPS becomes invalid, the locomotive will only be allowed to move a certain distance until a GPS Invalid Park State fault will occur.

3.6.6 Vigilance

The OCU is equipped with a Vigilance system. Whenever any speed selector on the primary OCU is out of STOP, a 60 second timer is started. If any OCU control has not been changed, or the vigilance reset function has not been activated for 60 seconds, the OCU sends a PARK command to the LCU, idles the locomotive and applies brakes. If a control vigilance reset has not been activated for 50 seconds, the OCU emits an audible alarm notifying. The operator that the locomotive will be commanded to the Park State in 10 seconds. When the vigilance audible alarm is heard, the operator must reset the vigilance timer. If the OCU Speed selector is commanding STOP, then Vigilance is disabled.

Test the vigilance system by placing the Speed Selector (SS) on the OCU in the Coast position. The train brakes should be set to prevent movement. The operator then lets the vigilance timer time out and verifies that the locomotive transitions to the Park State.

3.6.7 Fault Reporting

Fault reporting is provided to keep the system in a safe state, warn the operator of system abnormalities, and log events. Fault data is displayed on the OCU and the SCU.

OCU faults and critical LCU and locomotive faults are reported through the OCU display and audible alarm. The highest priority fault condition that is active in the LCU is displayed on the OCU until the fault is cleared. In addition, when the LCU has a restriction in effect that prevents it from honoring a command request form the OCU, it sends information back to the OCU so the OCU can provide an alert and display the reason the request is not being honored.

Detailed fault information is displayed on the SCU display in the locomotive for the Operator or Maintenance personnel. A complete listing of faults and the system reaction is provided in Appendix A.

3.6.8 Operator Down

The OCU provides the capability to detect an operator down situation. The OCU is equipped with a tilt sensor, which detects when the OCU is tilted beyond 45 degrees from the horizontal plane and if so, sounds an audible warning alarm for 5 seconds and the display indicates OCU Tilted > 45 deg. Place OCU Upright. If the OCU is not brought back within 40 degrees during those 5 seconds, the OCU displays Primary Operator Down, Place Ind Brk in Emergency, sounds a continuous high-level audible warning, and transmits a warning to the LCU. When the LCU receives this Operator Down command, it puts the train in the Safe state. If the OCU is not righted after 10 seconds uses the RCL system transmits a 9-1-1 tone followed by a Locomotive xxxx, Operator Down voice message over the locomotive voice radio. If the OCU tilt is corrected within the 10 seconds, the voice message is not transmitted. If a Secondary OCU is linked, the operator down function is active on both OCUs and functions the same. When an operator down is detected, both OCUs will display the alarm message with initiating OCU identified.

Recognizing that there are times when the operator may need to tilt the OCU during normal operations, a tilt by-pass feature is included which allows the operator to intentionally delay the operator down tilt sensing if the train is stopped. When the TOR actuator is pressed and released with the OCU in a non-tilted orientation, the OCU starts a 60 second tilt by-pass

GE Transportation Systems Global Signaling, LLC Proprietary and Confidential

3-20

Document No. 5002866 Rev. C (DRAFT)

28 April 2003

timer and preempts the normal tilt/operator down process. The Tilt O/R indicator flashes and the display indicates Tilt Override Active, Timer Set to 60 Sec. If the OCU is in the tilted state when the tile by-pass timer reaches 50 seconds, the OCU will output the audible operator alert that the tilt by-pass timer is about to expire and display Tilt O/R Expiring, Press Tilt O/R Again. If the operator press the TOR actuator any time during the 60second tilt by-pass time, the OCU restarts the timer. Pressing any other button or actuator on the OCU cancels the Tilt Override timer. The timer extension at is only 15 seconds while theSS is out of STOP, with no extension allowed at MAX speed.

If the OCU is tilted and the 60-second tilt by-pass timer expires, the OCU will display

Operator Down, Put OCU Upright, exit the tilt by-pass state, then display OCU Tilted > 45 Deg, Place OCU Upright. If the OCU is not righted, then the OCU transmits an Operator Down warning to the LCU and continuously sounds the high level audible

warning. If not corrected within 10 seconds, then the SCU transmits the operator down message. If the OCU is not tilted and the 60-second tilt by-pass timer expires, the OCU will

exit the tilt by-pass state and resume normal tilt sensing. For Test purposes, if the TOR is pressed and continuously held while the OCU is tilted, it

enters the Tilt Test Override mode. A ten second timer is started and normal tilt sensing is enabled except that the OCU transmits a Tilt Test Override message to the LCU at the 3second timeout. If the tilt test override timer reaches 10 seconds, the OCU transmits a normal Operator Down message to the LCU.

3.6.9 Communication Loss

The RCL system continually performs communications checks. These checks are performed by both the OCU and the LCU. If a check is unsuccessful, the following functions occur:

1. Loss of communications from the controlling OCU to the LCU for more than 5 seconds forces the LCU to go to the Park State (10 seconds if the loco is stopped). Likewise, if the communications from the OCU to the LCU is lost for 35 seconds, the OCU commands the LCU to go to the Safe State. The operator will be alerted to the communication loss by an audible alarm and a Primary Comm Loss message on the OCU display. In addition, the LCU indicates the communication loss by sending a communication loss message to SCU where the SCU illuminates the Primary OCU

radio Comm LED on the LED status indicators and displays the Communication Loss with Primary OCU message on the display.

2. Loss of communications from the controlling OCU to the LCU for 5 minutes forces the LCU to go to the Setup State and the OCU will automatically be unlinked.

3. Loss of communications from the secondary OCU to the LCU for more than 10 seconds causes the LCU to send a secondary OCU Communication loss message to SCU and forces the LCU to go to Park State. After 5 minutes of sustained Comm Loss, the OCU will be unlinked.

3.6.10 Battery Monitor

The OCU is powered by 1 rechargeable battery. The operator will be provided the estimated number of minutes of charge remaining on the batteries on the OCU status

display. The operator receives notification via the OCU display when the battery charge calls to 60 minutes, 45 minutes, 30 minutes, 15 minutes, 10 minutes and 5 minutes.

3.7 Event Recorder

The RCL system contains a Event Recorder System. These include the recording of event data, transferring of data to the display unit, the previewing of data and the printing of data. Event Recorder is covered under the service manual.
