RAILKING NW-2 DIESEL ENGINE

OPERATING INSTRUTIONS

Thank you for purchasing the RailKing® production of General Motors’ NW-2 diesel engine. The engine’s durable ABS body and die-cast trucks are traditionally sized for operation on any O-27 Gauge track. The engine should operate for years with any compatible AC transformer (see the chart on page 35 for a list of compatible transformers) and is completely compatible with most 3-rail locomotives, rolling stock and accessories.

The locomotive is equipped with either an electronic horn or the ProtoSound® Digital Sound and train control system which contains several deluxe features that are simple and fun to operate. Each feature is described among the following pages which should be read before the engine is operated. For those of you who can’t wait to get started, the Quick Start Basic Operating Instructions found on Pages 3 and 4 should be read so that you understand the basics of the operating system. Please note that some features are only found in the ProtoSound® models and are marked as such. Features not marked as ProtoSound® features are available in all models.

QUICK START - BASIC OPERATION

The RailKing NW-2 contains state-of-the art electronics with several builtin automatic features for incredibly realistic operation. Despite these advanced features, the NW-2 is easy to operate with any compatible standard AC transformer (see the compatibility chart on page 35).

All models are controlled by a ProtoSound® DCRU® electronic reverse unit. The reverse unit operates in the same manner that all reverse units function by using forward, neutral and reverse states that are entered each time the throttle is turned on and off or by using the transformer direction switch (if so equipped).

The reverse unit is designed to ignore dirty track, dead spots on switches or minor short circuits without disrupting the engine operation, even at slow, prototypical speeds. Once the engine is placed on the track, the throttle on the transformer can be advanced. You will see that only the engine’s lights come on and that only two dings of

the ProtoSound® bell occur followed by the diesel start-up sounds (on ProtoSound® equipped 3-rail models). The engine does not run.

This is known as the RESET state and is explained in more detail

beginning on Page 4. The ProtoSound® DCRU® will not power the motors until the throttle is turned OFF and then ON again.

Figure 2: DCRU Cycle Phases

At this point, the engine will now

function just like any other electronic or mechanical E-unit. On ProtoSound® equipped engines, the diesel engine sounds will change in volume as the engine begins to move. The horn can be activated by pressing the whistle button on the transformer just as any horn would be activated. See the sections later in this guide, beginning on page 5, for more information on activating the horn and bell sounds.

Each feature is described among the following pages. Though the system is easy to use, we encourage you to read the instructions thoroughly.

ProtoSound® DCRU® REVERSE UNIT

As mentioned in the Basic Operating section, the engine is controlled by a ProtoSound® DCRU® reverse unit that contains the standard forwardneutral-reverse states found on most reverse units. However, as described earlier, when power is first applied to the track, the reverse unit begins in RESET or what seems like a neutral state. Power must be interrupted again to get the locomotive to enter the forward state. It is this first RESET state that gives ProtoSound® its unique, remote controlled functions. The system will enter RESET whenever power to the track is off for three or more seconds. NEUTRAL will be referred to as the state between Forward and Reverse.

ProtoSounds® is equipped with a microprocessor, that, depending on the amount of memory it is allotted, allows the user to utilize several remotely activated functions. In the simplest terms, ProtoSounds® has its own “Computer" controlling these functions. In fact, the power of this microprocessor is the same as that of a 286 desktop computer! In order to access many of these remotely controlled functions, the user must be in the RESET state to do so. RESET is entered anytime power to the locomotive has been off for more than 3 to 5 seconds. When the engine first enters RESET, the microprocessor initiates a system check to determine if the system, transformer and engine are operating correctly. This takes

RAILKING

RailKing NW-2 Operating Manual

Page 5

approximately 2.2 seconds during which you will hear the engine’s startup sounds begin. In order for ProtoSounds® to properly initiate the system check, do not advance the transformer throttle past 10 volts when you first enter RESET, wait for the diesel startup sounds to begin and then slowly turn the transformer throttle to the off position and then back on again to enter the forward phase. Interrupting the power too quickly may cause the system to re-enter RESET (signaled by two dings of the bell). Should this happen, wait longer before interrupting the power to enter the Forward phase.

ProtoSounds® comes with several programmable functions, including Engine Volume Adjustment, Separate Bell Button Operation (preprogrammed at the factory), Cab Chatter On/Off Control, ProtoCoupler On/Off Control and Horn-In-Neutral Operation. Each of these features are described in more detail later. You will notice that when in RESET, your engine will not respond to the whistle button with a horn blast or continuous bell ringing. In fact, when in RESET and the whistle button is depressed, only one single bell chime will be heard each time the whistle button is pressed. If you don’t want to configure or change your locomotive using any of these programmable features, simply leave RESET and wait 2.2 seconds before interrupting the power to put the engine in forward. After you leave RESET, your engine will operate normally in all the direction states of forward, neutral and reverse.

HORN OPERATION

Your RailKing NW-2 ProtoSound® equipped engine is equipped with a digital recording of a diesel horn. The horn sound can be activated anytime the engine is in forward or reverse by pressing the whistle button on your transformer. The horn will continue to blow as long as the whistle button is depressed. The horn will not function in RESET and must be configured through a RESET option to allow the horn to work when the engine is in neutral. See page 17 for information on horn programming in the Using RESET To Program ProtoSounds® section of this manual.

BELL OPERATION

Your RailKing NW-2 ProtoSound® equipped engine is equipped with a digital recording of an actual diesel bell. Unlike previous versions of ProtoSounds®, the bell can be turned on or off with any separate bell button, like the Lionel® Railsounds® No. 5906 Bell Button, by simply

RAILKING

RailKing NW-2 Operating Manual

Page 6

pushing the button. If you don’t have a separate bell button, the bell can be controlled through your transformer’s whistle button whenever the engine is in NEUTRAL. The bell will never ring continuously in RESET (Remember NEUTRAL is the state between Forward and Reverse). Once the bell is turned on, it will continue to ring when the engine is cycled into forward or reverse until you press the bell button or re-enter NEUTRAL and turn the bell off with the whistle button.

In fact, because of ProtoSounds® state-of-the-art design, the microprocessor remembers its last command. Therefore, unless you turn the bell off before you quit running your train, the next time you run the engine, the bell will come on. No matter whether you come back an hour later or a year later, the bell will begin chiming once the engine enters one of the three directional states.

To turn the bell on using the transformer’s whistle button, turn on power to the track and cycle the engine into NEUTRAL. Turn the throttle to 8 volts or less (any higher voltage will arm the ProtoCoupler™) and press the whistle button. The bell should begin chiming. To turn the bell off, press the whistle button again. If you want to keep the bell on while running the engine, simply interrupt the power with the transformer throttle or the transformer directional switch and enter forward or reverse.

PROTO-COUPLER™ OPERATION

Your RailKing NW-2 ProtoSound® equipped locomotive has two coilwound ProtoCouplers™ for remote uncoupling action. The couplers are mounted on the power trucks. Because the ProtoCoupler™ is controlled through ProtoSounds® microprocessor, it doesn’t’t require an uncoupling track section or modification to your layout to function. The three simple steps below are required to operate the coupler.

1. Put your engine in NEUTRAL and turn the throttle all the way up.

2. Press the transformer whistle button to “Arm" the coupler. (You will hear a “Clank")

3. After arming the coupler, press the whistle button again to open the coupler.

Page 7

When the knuckle fires open you will hear the buzzing of the coil energizing and the sound of the air lines coming apart. It can best be described as a CHA-CHUSHHH sound. The coupler doesn’t’t have to be fired in NEUTRAL. Once the coupler is armed it can be fired in Forward, Neutral or Reverse. However, you may find that the coupler doesn’t’t open when firing the coupler at high speeds. Reduce the voltage setting on your transformer if this occurs and run your engine at a slower speed before firing the coupler. If the coupler continues to open erratically, try lubricating the knuckle with light oil as indicated in Fig. 3.

For multiple heading purposes, only one of the two ProtoCouplers™ will function at any one time. Use the coupler direction switch as shown in Fig. 5 on page 16 to select either the front or rear coupler. Simply slide the switch toward the direction of the coupler you want to make active.

SQUEAKING BRAKE SOUNDS

ProtoSound® equipped engines feature the ability to play the sound of squeaking brakes whenever your engine slows in speed. There are two settings for activating the squeaking brake sounds. The default setting allows the brake sounds to play while the engine is in forward or reverse and the transformer throttle is lowered from a high setting to a low setting (14 volts to 8 volts or less). The second setting requires that a bell button be used to “arm” the brake feature and is explained in more detail in the “Activating Freight Yard Sounds” section found later in this manual. The sound itself is a stored record on the ProtoSounds® software chip and will always play the same brake sound for the same three second length each

Throttle Down From High Voltage To Low

Listen For The

Squeaking Brake Sounds

Squeeek

RAILKING

RailKing NW-2 Operating Manual

time the voltage is reduced from high to low. Some practice may be required to synchronize the playing of the brake sounds with the movement of the engine. It is not uncommon for the engine to stop before the brake sound is completed. Operators will find that by coordinating the movement of the throttle setting from 8 volts to off will allow the engine to maintain its movement while the brake sounds play. Note: The brake sounds will not

be heard if the transformer throttle is not set above 14 volts and/or not reduced below 8 volts.

TIPS ON USING THE SQUEAKING BRAKE FEATURE

Because the squeaking brake feature always plays for approximately 3 seconds, it is possible that the brake sounds will play longer or shorter than what visually seems prototypical. You will find that by practicing with the brake feature, you can quickly determine how quickly to throttle down and what speeds and voltage settings give you the most prototypical braking effect.

Typical users will find the feature to be a very realistic way to simulate the sound of an engine slowing down for curves, crossings or coming to a stop at a station, side track or switch yard. As mentioned above, you will find that initially your engine may continue to play the brake sounds once your engine comes to a stop or that the sounds stop prematurely before the engine comes to a complete halt. For example, if you simply run the engine and turn the throttle off quickly, the brake sounds will likely continue playing even though the engine has come to a complete stop. This annoying effect can be eliminated by simply practicing with the brake feature. In no time, you will quickly learn how to feather" the throttle to keep the engine moving while the brake sounds play and then turning the throttle off just as the sounds stop. Remember that once you stop the engine, you should turn the throttle to the off position if you dont want to activate the Freight Yard Sounds feature described later in this manual.

The ProtoSound® squeaking brake feature also has the ability to simulate the squeal of wheel flanges when your train enters a curve at high speeds. The same brake squealing sound plays, but you dont need to reduce the transformer throttle to activate the squealing sounds. To play the squealing sounds as wheel flange sounds, trigger the brake feature using either method 1 or 2 above. Once triggered set the transformer throttle setting at 14 volts or higher. As your engine enters a curve (or anywhere on the layout) quickly flick" your transformer whistle button about half way. This flicking" action causes the transformer to release a short DC signal that ProtoSounds® reads as an indicator to activate the brake sounds. The engine wont slow down even though the sounds play. This simulates the wheel flange squeal of a train traveling through a turn too quickly.

Note: Consistent activation of the wheel flange squealing is determined by the condition of your transformers whistle button rectifier disc. Older rectifier discs may not release a clear and strong enough DC signal required by ProtoSounds® computer to play the wheel flange squealing.

FREIGHT YARD SOUNDS (FYS)

ProtoSounds® comes equipped with operator controlled Freight Yard Sounds, hereby referred to as FYS. This easy to use feature plays digitally reproduced freight yard sounds whenever your engine stops on your layout and is parked in the Neutral position. No additional wires or modifications are needed on your layout to enjoy these amazing sound effects. The sounds themselves are randomly generated and randomly “shuffled” on the ProtoSounds® software chip. This gives the system the ability to produce different sounds in a different order each time FYS is enabled. These different sounds are heard each time you cycle the transformer throttle from ON to OFF in the same manner that you would cycle the throttle to enter the various states of Forward, Neutral and Reverse. The entire FYS sequence is designed to simulate the arrival, loading or unloading and departure of a freight train in a freight yard. Each sequence is described in more detail in the following sections.

ACTIVATING FREIGHT YARD SOUNDS

Your ProtoSounds® equipped engine features an operator controlled freight yard sound set. Once activated, this easy to use feature plays the sound of freight yard activities whenever the operator places the engine in the neutral position.

ARMING THE FREIGHT YARD FEATURE

Before the freight yard sounds can be heard, ProtoSounds® must activate the feature so that the next time the engine enters the neutral position, the sounds can play, The feature can be activated one of two ways.

Option 1: If you are using a separate bell button controller to ring your

bell (like the Lionel Railsounds® No. 5906 bell activation button) you can activate the feature by pressing and holding the bell button for three seconds or longer (it doesn’t matter if you are in forward, neutral or reverse). You will hear the bell chiming turn on and if you listen carefully you should hear an air release sound after three seconds have passed at which time you can

release the bell button. (Note: because the air release sound is hard to

hear, we recommend that you count out a full three seconds before releasing the bell button.) The bell will continue to chime, so if you want to

turn off the bell ringing, simply press and release the bell button a second time. If you were in neutral when you triggered the brake feature, interrupt the transformer throttle to enter either forward or reverse to allow the

engine to begin running. (

Note: the feature will only be activated in the

first direction state you enter after triggering the feature from the neutral position. You cannot interrupt the power twice to enter another direction state and still have the brake feature active.) Once your engine begins

running, you can trigger the sounds to begin playing whenever you enter neutral.

Option 2 If you do not have a separate bell button on your layout, you can

still activate the feature with your transformer whistle button. To activate the feature turn on the transformer throttle and get your engine into the neutral position (not RESET). Once in neutral, set the transformer throttle at 8 volts or less and press and hold the whistle button for at least three seconds. You will hear the bell chiming turn on and if you listen carefully you should hear an air release sound after three seconds have passed at

ACTIVATING AND TRIGGERING FREIGHT YARD SOUNDS

Before FYS can be heard the feature must be activated first. Activation is accomplished by holding down the bell button for three or more seconds as described in the Activating and Triggering The Squeaking Brake Sounds section found earlier. Once the feature is activated, FYS will be played the next time the engine enters the neutral position. In order for FYS to begin, power must remain on once the engine enters the Neutral position. At this point ProtoSounds® has taken over control of your engine and disabled the bell and whistle buttons from any further operator functions. In addition, ProtoSounds® has reconfigured the way the reverse unit functions by disabling the reverse unit state during operation of the FYS feature. This forces the engine to leave your freight yard in the same direction it arrived in. The following operator controlled “events” control FYS’s actions and sounds.

Event 1 (Forward) While the locomotive is running in forward (or reverse) FYS is activated by the operator pushing and holding the bell button down for three or more seconds. The locomotive bell begins chiming and can be left on or turned off without disabling FYS.

Event 2 (Neural Before Reverse) The operator now interrupts the transformer throttle to stop the engine and put it into Neutral. If the throttle setting was at 14 volts or higher , ProtoSounds® will play the sound of squeaking brake sounds as the engine comes to a halt.

A. Upon stopping of the engine, the operator must immediately turn the throttle back on to keep the engine in the Neutral position. If the bell was not turned off after activating FYS, it now turns off automatically.

Note:

3 seconds of leaving the Forward phase will disable FYS and shutdown ProtoSounds®. The next time you turn power back on your engine will be in the RESET position. See page 4 for more information on RESET.

B. After entering Neutral, ProtoSounds® will immediately play an air release sound followed approximately 2 seconds later by a Cab Chatter Arrival Message. The arrival message announces what yard the engine has arrived in (the yard is described as either Yard A or Yard B, alternating each

time FYS is enabled during the current operating session. If the engine is turned off for more than three seconds, ProtoSounds® will automatically return to the Yard A message the next time FYS is enabled). Immediately following the arrival message, the sound of freight car doors can be heard opening, followed by the sounds for forklift engines. At this point various freight yard sounds can be heard including forklift operation, engine sounds, reverse warning horn beeps, and additional freight car door sounds.

Event 3: (Reverse) The operator now interrupts the transformer throttle again to enter the next reverse unit phase; reverse. In an effort to enhance realism, FYS has disabled the reverse phase so that it doesn’t power the motors causing the engine to move backward. Upon entering reverse, FYS confirms to the operator that it has entered the reverse phase by immediately playing a highlight sound best described as a rumbling sound. You may have to go

through the entire FYS sequence several times before you can clearly identify this sound. After the rumbling highlight is played, the freight yard sounds heard in Event 2 continue to play randomly.

Event 4: (Neutral Before Forward) The operator now interrupts the transformer throttle again to enter the next reverse unit phase, neutral before forward. FYS confirms to the operator that it has entered the neutral before forward phase by emitting two quick air release sounds. This is followed by a Cab Chatter message that the engine in Yard A or B (whichever yard designation was played in Event 2) is preparing to depart the yard. Upon completion of the cab chatter

message, the freight yard sounds change as the forklift sounds turn off and the freight car doors begin shutting.

Event 5: (Forward) The operator now interrupts the transformer throttle again to enter the next reverse unit phase; Forward. FYS confirms to the operator that it has entered the Forward phase by playing the sound of the freight car door closing. Within 2 seconds of the door closing, the locomotive bell begins chiming,

TIPS ON USING FYS FEATURES

FYS is a unique feature of ProtoSounds® that is completely controlled by the operator. You decide how, when or if you want to utilize the feature. By reviewing the following tips, you should find solutions or suggestions to the various operating scenarios you might encounter when using FYS.

Tip #1:

throttle before the first Cab Chatter message plays in Event 2 (neutral before reverse).

Tip #2:

Off for 15 seconds.

Tip #3:

example, if you activate the FYS feature while in Reverse and interrupt the throttle to enter Neutral, you will be entering Neutral Before Forward rather than Neutral Before Reverse as defined in Event 2 above. Consequently, the Forward phase will be rendered inactive by ProtoSounds® instead of the Reverse phase as explained in Event 3. This will allow your train to leave the yard in the same reverse direction that it arrived in.

You can escape the FYS sequence by interrupting the transformer

You can terminate FYS at anytime by turning the transformer throttle

You do not have to be in the Forward phase to utilize FYS. For

Tip #4:

engine regardless of whether the second engine is equipped with an FYS programmed ProtoSound® module. If the second engine isnt equipped with FYS, the only thing to remember is that you not turn up the transformer throttle very high when entering the Reverse phase found in Event 3. If the throttle is set too high, then the second locomotive will begin vibrating on the track as its motors will be turning in the reverse state since they cannot be disabled automatically like FYS equipped engines. If your second engine is equipped with FYS, you may want to disable it when used in double-headed operations. To disable FYS, see the section on programming RESET functions on page 28 of this manual.

You can utilize FYS even if you are double-heading with another

Tip #6:

state by simply interrupting the transformer throttle. Any sound effects programmed to play in that event will simply not occur. The only exception is Event 2 and Event 5. In Event 2, interrupting the throttle has no effect on FYS until after the arrival Cab Chatter message has completed and the freight car doors have opened. In Event 5, you cannot interrupt FYS until after the engine begins to move. Interrupting the throttle before the engine begins to move has no affect on the locomotives operation.

SELF-RECHARGING BATTERY BACKUP SYSTEM

ProtoSounds® state-of-the-art design includes a self-recharging battery backup system for improved performance at any speed. The self-recharging battery backup system is automatically turned on or off whenever track power is turned on or off. There are no switches to turn on or off to enjoy the benefits of the automatic battery backup system. The battery ensures that power to the sound system will remain on during directional changes, setting RESET options, or when traveling over dirty track and switches.

The battery is a rechargeable NiCad type which is continually charged from the track when power is applied. NiCad batteries are a dry battery and should not leak or cause any damage to your locomotive and will last up to five years or longer. If you notice that the sounds seem distorted or garbled at low voltages or become silent when power from the transformer is shut off, the battery may be going bad. Before replacing the battery, you should put the engine in NEUTRAL and leave the transformer throttle at about 12 volts for fifteen minutes. This should temporarily recharge the battery. If the garbled or distorted sounds are reduced, then your battery charge has worn down. You can give your battery a full charge by leaving the engine ON in NEUTRAL for 16 to 18 hours.

REPLACING THE PROTOSOUND® BATTERY

If you notice that the sounds seem distorted or garbled at low voltages or become silent when power from the transformer is shut off, the battery may be going bad. Before replacing the battery, you should put the engine in NEUTRAL and leave the transformer throttle set at about 12 volts for 15 minutes. This should temporarily recharge the battery. If the garbled or distorted sounds are reduced, then your battery charge has worn down. You can give your battery a full charge by leaving the engine ON in the NEUTRAL position for 18 hours. (Make sure the smoke unit switch is in the OFF position to prevent harm to the smoke unit wicking).

If you need to replace the battery, replacement ProtoSound® batteries are available from MTH ProtoSound® Electronics at 7020 Columbia Gateway Drive, Columbia, MD 21046. A standard 9v alkaline battery can be substituted as a temporary fix, but since alkaline batteries can’t take a charge, it will eventually wear down. Regardless, it should give you a week to a couple of months use while you wait for your replacement ProtoSound® battery to arrive.

PROTOSOUND® VOLUME ADJUSTMENT

Your ProtoSound® system has two types of volume adjustment. A manual turn knob on the bottom of the chassis (See Fig. 4 below) allows you to control all the sounds in the system and a remote control “RESET" option (Option # 6), allows you to control the volume level of the engine sounds remotely from the transformer. Turning the volume adjustment knob clockwise will increase the volume and counterclockwise will lower the volume of all sounds; bell, horn, engine sounds, Cab Chatter, etc.

USING “RESET" TO PROGRAM PROTOSOUNDS®

As mentioned earlier, there are several programmable options in each ProtoSound® equipped engine that can be remotely set from any compatible standard AC transformer equipped with a whistle button. For a list of compatible transformers, see the chart on page 35. This hands-off approach gives you unprecedented control of your railroad empire’s motive power never before seen in model railroading. Each programmable feature can be accessed whenever your engine is in the RESET state as described earlier on page 4. By following the instructions below you will find the programming easy and straight forward.

ENTERING RESET OPTIONS

ProtoSound® is equipped with a few programmable features that are accessed in the RESET state by moving the transformer throttle up and down between full voltage and low voltage (6 to 8 volts) without shutting the transformer off completely. Each time this is done you advance, one feature at a time, through the available options. An air-release sound is heard each time the throttle is advanced. In addition, there are special sounds to tell you what RESET position you are in.

For example, if you want to select Feature 2, you put the engine in RESET, and move the throttle up and down from full throttle to low two times. After the second advance, you will hear two “clinks" indicating that the computer is now in Feature 2. Advance the throttle again and you will hear three “clinks" for Feature 3. Advance it two more times and you will hear a “clank" indicating that you are now in Feature 5. Advance the throttle two more times

RAILKING

RailKing NW-2 Operating Manual

Page 18

times the throttle is advanced by playing back the number of “Clinks" and “Clanks" to confirm the feature you’ve selected.

SETTING THE ENGINE VOLUME

Of all the sounds that come with each ProtoSound® equipped locomotive, the one most often turned down is that of the engine volume because it is the one sound normally heard whenever the engine is running and is what usually can become tiresome to the ear over prolonged running sessions. The volume adjustment is controlled through RESET Feature 6.

To access the feature, advance the transformer throttle to put the engine in RESET. Move the throttle up and down, as described on page 17, 6 times. After you hear the “clank" and “clink" indicating that you are in Feature 6, press the whistle button to select the engine volume level you desire. Pushing the whistle button once will give you full volume, which is the factory setting. Pushing the whistle button a second time will give you 50% volume, pushing it a third time will give you 25% volume and pushing it a fourth time will give you no engine sound. The microprocessor will immediately play the sound level each time the whistle button is pushed so that you can decide if it is acceptable. You can recycle through the four choices by simply continuing to press the whistle button.

PROGRAMMING FOR A SEPARATE BELL BUTTON CONTROLLER

To operate ProtoSounds® with a separate bell button controller, like the Lionel® No. 5906 bell button, you will need to wire up the controller to your transformer and track as shown in Fig. 5. Once the button is wired, ProtoSounds® comes preprogrammed to allow you to operate the bell by simply

Note: When Horn In Neutral" is set, the bell will only operate with a separate bell button and the horn will not sound in neutral if the transformer throttle setting is over 11 volts. At 11 volts or higher, ProtoSounds® may arm the coil coupler for operation whenever the whistle button is pressed and the engine is in neutral.

TURNING OFF CAB CHATTER SOUNDS

“Cab Chatter" sounds occur in the neutral position every 2 to 30 seconds. There are four “Chatter" messages which play at random times. This helps to eliminate repetitive and boring messages. While the sounds are selected to play randomly by the unit’s computer, there is no guarantee that you won’t hear the same message repeated twice or more times. If you don’t want to hear the Cab Chatter sounds, they can be turned off through Feature

PROGRAMMING FOR PROTOCOUPLER OPERATION

ProtoSounds® comes with a RESET feature that allows the operator to remotely turn off the ProtoCoupler™ functions. This is especially useful when double or triple-heading ProtoSound® equipped engines since every engine equipped with a ProtoCoupler™ will fire when prompted to by the operator. By turning off the ProtoCoupler™ operation on certain engines, you can fire the couplers open on the other engines without uncoupling the engines from each other. To turn the ProtoCoupler™ function off, enter RESET and go to Feature

ACTIVATING REMOTE LOCK-OUT CONTROL

ProtoSound® equipped engines feature a RESET setting that allows the operator to remotely “lock” the engine into forward, neutral or reverse. This is especially useful on layouts that feature “blocked” track sections. The lockout feature comes from the factory in the OFF position, meaning it is not active when you first take the engine out of the box. This is done to prevent novice operators from accidentally locking their engine into forward, neutral or reverse and then mistakenly thinking that the engine’s electronics have failed. To activate the Remote Lockout Control setting, go to RESET Feature 40 (See the section entitled Using

RESET To Program ProtoSounds® on page

17). Once in Feature 40, press the transformer whistle button and wait for ProtoSounds® to sound a bell ding. Continue pressing the whistle button until ProtoSounds® sounds two bell dings signifying that the Remote Lockout Control has been selected. To lock in the setting, simply turn the throttle all the way off and then back on again. To turn the Remote Lockout Control setting back off, go back to Feature 40 and press the whistle button until only one bell ding sounds. To lock in the setting, simply turn the transformer throttle off and then back on again. Alternatively, you can go to RESET Feature 18 to reset all ProtoSound® features back to their original factory defaults including Remote Lockout Control.

REVERSE UNIT LOCK-OUT OPERATION

ProtoSounds® unique design eliminates the need for a lock-out switch on the locomotive by allowing the customer to lock the engine into any directional state (forward, neutral or reverse) from the transformer. This will allow users to run the engine on layouts equipped with block signals or stop stations which would normally cycle the engine back into neutral. The feature must be first turned on by accessing RESET Feature 40 (See section entitled Using RESET To Program ProtoSounds® on page 17).

LOCKING THE ENGINE INTO FORWARD OR REVERSE

To lock the engine into Forward or Reverse, use the transformer throttle to enter Forward or Reverse (whichever state you want to lock the engine into) and while the engine is moving press the whistle button. WHILE THE HORN IS BLOWING TURN THE THROTTLE OFF AND THEN LET GO OF THE WHISTLE BUTTON. After about one second, you will hear a short horn blast. QUICKLY TURN THE THROTTLE BACK ON AGAIN. Your engine is now locked into Forward or Reverse and it will remain so until you unlock the engine, even if you wait a year to run your engine again.

UNLOCKING THE ENGINE

Unlocking the engine is a similar procedure. WHILE THE ENGINE IS MOVING, PRESS THE WHISTLE BUTTON. WHILE THE HORN IS BLOWING, TURN THE THROTTLE OFF AND THEN LET GO OF THE WHISTLE BUTTON. After three seconds without power you will hear one chime of the RESET bell. TURN ON THE POWER AGAIN. Your engine is now in RESET and will operate normally once you interrupt power and enter the forward direction.

LOCKING THE ENGINE INTO NEUTRAL

To lock the engine into the NEUTRAL position, PUT THE ENGINE IN NEUTRAL AND WITH THE THROTTLE STILL ON, PRESS THE WHISTLE BUTTON. WHILE THE WHISTLE BUTTON IS BEING PRESSED, TURN OFF THE THROTTLE AND LET GO OF THE WHISTLE BUTTON. After about one second, you will hear a short blast of the horn. QUICKLY TURN THE POWER BACK ON AGAIN. Your engine is now locked into NEUTRAL.

OIL & LUBRICATION INSTRUCTIONS

In order for the engine to perform correctly and quietly, it is important that the chassis be lubricated before operation. Lubrication should include all truck block bushings and pickup rollers to prevent them from squeaking.

Lubricate (L)

Pickup Rollers

Grease (G)

Wheel Gears

Figure 6: Lubricating The Locomotive Chassis

Use light household oil and follow the lubrication points marked “L" in Fig. 6 above.

The locomotive’s internal gearing in both power trucks has been greased at the factory and shouldn’t’t need additional grease until after 50 hours of operation or one year whichever comes first. Grease cannot be added to the internal gearing until the body is removed from the chassis which is held in place by four Phillips screws. The screws are located on each end of the chassis’ as seen in Fig. 7 below. After removing the screws, lift the body away from the chassis and lay the body next to the chassis.

Next, remove the truck blocks from the chassis by unscrewing the large Phillips motor mount screw on the bottom of each truck block (See Fig. 7).

the truck block and lightly coat the motor worm gear and bronze drive gear (in the truck block) with grease. Reassemble the truck and motor, being careful not to pinch the pickup and ground wires between the truck block and motor mount. Repeat the procedure for the other motor and truck and then reassemble the chassis to the body. When reassembling the chassis and body, be very careful that the lighting wire harnesses are not caught between the body and chassis as this can lead to a short which may damage the electronic circuit boards beyond repair.

In addition to the truck block internal gearing, it is a good idea to lubricate the outside truck block “idler" and “drive" gears with grease. Use the diagram shown in Fig. 6. on page 27 as a guide and add grease to the points marked with a “G".

Periodically, check the locomotive wheels and pickups for dirt buildup as this can significantly affect the engine’s ability to perform properly. Dirty track and dirty wheels can cause both poor electrical contact as well as poor traction, especially on elevated track sections. Finally, dirt and oil build up can prematurely wear out the neoprene traction tires.

TRACTION TIRE REPLACEMENT INSTRUCTIONS

Your locomotive is equipped with two neoprene rubber traction tires on each power truck. While these tires are extremely durable and long-lasting there may arise a time where they will need to be replaced. Should this occur, you will need to remove the trucks and truck sides on the truck block from the chassis in order to slip the new tire over the grooved drive wheel. We suggest you follow the disassembly instructions found in the Lubrication section on the preceding pages to dissemble the chassis and truck blocks from the body.

Before the new tire can be installed, you must make sure the old tire has been completely removed from the groove in the drive wheel. Use a razor blade or small flatblade screwdriver pry away any remains left from the old tire that may still be in the drive wheel groove. Once the old tire has been completely removed, slip the new tire onto the wheel. You may find it useful to use two small flatblade screwdrivers to assist you in stretching the tire over the wheel. Be careful to avoid twisting the tire when stretching it

RAILKING

RailKing NW-2 Operating Manual

Page 29

over the wheel. If a twist occurs, the tire will have to be removed and reinstalled or a noticeable wobble in your engine will occur when operating the locomotive. In addition, it is important to make sure that the tire is fully seated inside the groove. Any portion of the tire extending out of the groove can cause the engine to wobble. A razor blade can be used to trim away any excess tire that doesn’t’t seat itself inside the groove properly.

Once the new tire(s) are in place, reassemble the truck sides to the truck blocks and then reassemble the chassis to the body. Replacement tires are available directly from MTH Electric Trains.

HEADLIGHT REPLACEMENT

The NW-2 locomotive contains one bayonet 18v headlight bulb that is controlled by the track voltage. The headlight bulb simply plugs into its lamp socket and can be easily removed should the bulbs expire. To remove the bulbs, follow the cab removal instructions found in the lubrication section on the preceeding pages. Once the cab has been removed from the chassis, gently twist and push the bulb to unlock it from its lamp housing. Once unlocked, the bulb will pull out of the socket. Replacement bulbs are available directly from MTH Electric Trains.

TROUBLE SHOOTING PROTOSOUND® PROBLEMS

Although ProtoSound® has been designed and engineered for ease of use, some questions may arise during initial operation. The following table should answer most questions. If you find that your problem can’t be resolved with this manual, contact MTH ProtoSound® Electronics (7020 Columbia Gateway Drive, Columbia, MD 21046, 410-381-2580) for additional assistance.

HORN PROBLEMS REMEDY

The horn seems distorted at low voltages.

When I press the whistle button, the bell comes on instead.

I cant get the horn to blow when I press the whistle button.

Your battery may be undercharged or dead. Try recharging the battery as explained in the battery sections.

You are trying to operate the horn in neutral. The horn will only operate in Forward or Reverse unless you program ProtoSounds through Feature 25. See the instructions in the section entitled Using RESET to Program ProtoSounds.

You may be pressing the whistle button too quickly. Most older AC transformers contain a two--step whistle button that releases a DC signal onto the track. It is this DC signal that tells the horn to blow. However, because the signal is weaker when the whistle button is depressed fully, the ProtoSound circuit may not recognize the signal. Try pressing the whistle button slower, taking approximately 1 second to fully depress the button.

BELL PROBLEMS REMEDY

When I press the whistle button to activate the bell, the horn sounds.

When I press the whistle button to activate the bell, I arm the coupler.

When I press the whistle button to activate the bell, the bell only rings once.

I cant get the bell to ring when I press the whistle button.

The bell wont work with a separate bell button.

You are trying to ring the bell in Forward or Reverse. The bell only operates in Neutral unless you have programmed ProtoSounds to recognize a separate bell button.

Reduce the voltage on the transformer before pressing the whistle button to activate the bell. The bell will only come on at 8 volts or less.

You are trying to ring the bell in RESET instead of neutral. Interrupt the power twice to enter Neutral, set the voltage at 8 volts or less and press the whistle button to activate the bell.

You may be pressing the whistle button too quickly. See the 3rd remedy in the horn section above.

ProtoSounds must be programmed in order for a separate bell button to function. Enter RESET function number 20 (see the section entitled Using RESET to Program ProtoSounds) and press the whistle button until the bell sounds two dings. Simply turn the throttle off and then on again to lock in the new setting.

You may be pressing the whistle button too quickly. See the third remedy in the horn section above. Another possibility is that ProtoSounds has been programmed to turn the coupler function off. See the section entitled Using RESET to Program ProtoSounds

Only one coupler can operate at any one time. Use the coupler selection switch on the bottom of the chassis to choose which coupler you want active.

DIESEL START/CAB CHATTER REMEDY

Sometimes the diesel start sounds dont occur when I first turn power on.

Sometimes the Cab Chatter sounds dont play.

Occassionally the diesel engine start up sounds may not occur when power is turned back on within 5 seconds of being shut off. Wait 10 -- 15 seconds before repowering.

The Cab Chatter sounds only play in neutral and ProtoSounds may be programmed to turn thesounds off. See the section entitled Using RESET to Program ProtoSounds

LOCKOUT PROBLEMS REMEDY

I cant get the engine to run after I power up the transformer. It sits still with the diesel compressor sounds running.

The engine wont lock out into Forward, Neutral or Reverse even after the short horn blast sounds.

The engine is locked out into the Neutral position. Follow the unlocking proceedures in the Lockout Section.

You are waiting too long to turn the throttle back on after the short horn blast sounds. The power must be turned back on immediately after the short horn blast sounds or the engine will go back into RESET. See the lockout proceedure in the Lockout Section.

VOLUME PROBLEMS REMEDY

You are trying to set the volume with a poorly charged or dead backup battery. See the section on Battery Backup for more information.

When the diesel volume is set to O, you will hear the Cab Chatter sounds because setting the diesel volume only controls the sound of the diesel engine itself. All other sounds, including Cab Chatter, the horn and bell will continue to play at the volume level set by the manual volume control knob located on the bottom of the chassis. See the section entitled ProtoSound Volume Adjustment for more information.

The overall ProtoSound volume has been set to high creating the distorted sounds. Try turning the volume control knob located on the bottom of the chassis counter clockwise to reduce the overall volume level.

RAILKING

BATTERY PROBLEMS REMEDY

I get no sounds when the engine shifts between the direction states.

After I turn off my transformer, my engine continues to make sounds before quitting with a ding of its bell.

The sounds distort at low voltages.

A repeating horn blast occurs after the power has been shut down.

The battery may be dead or needs charging. See the Battery Backup section for more information.

ProtoSounds continues to sound for approximately 10 seconds after power to the track has been shut off.

The battery is insufficiently charged or dead. Follow the recharging instructions found in the section entitled Self Recharging Battery Backup System.

first turned on, ProtoSounds enters a RESET phase at which time the engine undergoes a system check. Power must be interrupted to get the engine into the Forward Phase. See the section entitled DCRU Reverse Unit Operation for more information.

Whenever ProtoSounds enters RESET after power has been off for more than 15 seconds, the microprocessor initiates a system check to determine that everything is in working order. This system check requires 2.2 seconds to complete during which time the engine will play the diesel startup sounds. We recommend that you dont interrupt the power in RESET until the diesel startup sounds have completed. This will guarantee that the system check will have been completed since the startup sounds take longer than 2.2 seconds to play. If the problem persists, we recommend that you operate the throttle with a slower movement as you interrupt the power in RESET and enter the Forwaard Phase

BRAKE SOUND PROBLEMS REMEDY

When the transformer is throttled down, the sounds wont play.

The brake sounds continue to play even after the engine stops.

The brake feature was activated in neutral after the engine was running in forward, but the brake sounds would not play when triggered after the engine went back into forward or reverse.

After triggering the brake sound and stopping the engine in neutral, the engine begins making passenger station sound effects.

information.The throttle voltage setting on the transformer is either not starting high enough or ending low enough to trigger the brakes sounds. Try increasing the throttle setting to 14 volts or higher before throttling down to 8 volts or less.

The brake feature sound record lasts for three seconds. With practice you can control how quickly you should stop the engine to keep it in sequence with the sound of the brakes squeaking.

The brake feature will only remain enabled if it is triggered in the first direction state you enter after activating the feature in neutral. You cannot interrupt the power twice to enter another direction state and still have the brake feature active. Therefore, in order to make the brake sound feature operate in forward, you must first activate the feature in the neutral position that occurs after the engine was in the reverse state.

After you trigger the brake sounds, you cannot stop the engine in neutral and leave the track power on without activating the passenger station sounds. If you dont want to hear the passenger station sounds after entering neutral, turn the power off for three seconds to disable the passenger station sound effects.

enter the neutral state thus disabling FYS.The transformer throttle was interrupted too quickly in neutral thus disabling FYS. Leave the throttle on in neutral until after the FYS arrival message plays.

ProtoSounds has a built--in random number generator that randomly selects each sound clip to play. Because there are only a total of 8 sound clips available in each FYS event, it is probable that a sound can occassionally be repeated one or more times.

So that the passenger station sound effects and operation is as realistic as possible, ProtoSounds disables the reverse unit state whenever FYS is enabled. This way the engine never goes into reverse as the operator cycles through the various FYS events.

FYS has a built--in command to turn on the bell when the system enters Event 5. After approximately 15 rings of the bell, it automatically will turn off.

Because FYS must control various effects in each FYS event, the bell and whistle functions are disabled until either the FYS events have been completed, or the engine is shut down for 3 or more seconds.

It is possible that FYS was never enabled or has been disabled. Try reactivating the feature by holding down the bell button for three or more seconds.

TRANSFORMER WIRING CHART

ProtoSounds® is designed to work with any standard AC transformer that uses a “Pure Sine-Wave" format. The chart below lists the many Lionel® compatible transformers, such as the Lionel KW or ZW models. In addition, the chart details how the terminals on these compatible transformers should be attached to your layout. The Trainmaster system from Lionel® (marked with an asterisk below) will not function correctly with ProtoSounds® without disrupting the sound effects. Therefore, whenever ProtoSounds® senses that the Trainmaster system is being used, it automatically disables ProtoSounds® sound effects. The operator retains control over the engine, but no sound effects will play.

O-27 OPERATION

While the RailKing NW-2 diesel is more than capable of operating on O27 curves and switches, you may find that certain light freight cars are prone to derailing when being pulled or pushed by the RailKing NW-2 through O-27 switches. Should this occur, we suggest adding weight to the cars making them heavier and less likely to derail. In addition, the 6-wheel version may rub the switch box.
