Thank you for purchasing the MTH Electric Trains Premier GG-1 Electric
locomotive. This ¼” scale reproduction of the famous GG-1 Electric
Locomotive measures over 19 3/4” in length and weighs over 8 pounds.
Despite its scale size, the locomotive is capable of operating on O-72 3-rail
track with any compatible AC transformer (see the chart on page 33 for a
complete list of compatible transformers and wiring instructions) and is
completely compatible with most other 3-rail locomotives, rolling stock and
accessories.
The locomotive is equipped with 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.
The MTH GG-1 contains state-of-the art electronics with several built-in
automatic features for incredibly realistic operation. Despite these advanced
features, the GG-1 is easy to operate with any compatible standard AC
transformer (see the compatibility chart on page 33).The GG-1
locomotive is 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. At this point, the engine will now function just like any other
electronic or mechanical E-unit.

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
PREMIER LINE
MTH GG-1 Operating Manual
4
system, transformer and engine are operating correctly. This takes
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.
PREMIER LINE
HORN OPERATION
Your MTH GG-1 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 UsingRESET To Program ProtoSounds® section of this manual.
BELL OPERATION
Your MTH GG-1 ProtoSound-equipped engine is equipped with a digital
recording of an actual electric 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 pushing the
MTH GG-1 Operating Manual
5
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 MTH GG-1 ProtoSound-equipped locomotive has two coil-wound
Proto-Couplers® for remote uncoupling action. The couplers are mounted
on the leading power trucks of each A Unit. Because the Proto-Coupler® is
controlled through ProtoSound’s microprocessor, it doesn’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.

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 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 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 Proto-Couplers will
function at any one time. Use the coupler direction switch as shown in Fig.
1 on page 3 to select either the front or rear coupler. Simply slide the
switch toward the direction of the coupler you want to make active.

NEUTRAL-ACTIVATED CAB CHATTER SOUNDS
Your engine is equipped with four dispatacher-to-engineer “Cab Chatter”
radio transmissions that occur every 2 to 30 seconds. Each sequence will
play at random intervals to eliminate repetition. While the sounds are
selected to play randomly by the microprocessor, there is no guarantee that
you won’t hear the same message repeated twice or more times.
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
Throttle Down From
High Voltage To Low

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 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.
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.
PREMIER LINE
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
The ProtoSound® battery is a special NiCad 7-cell, 8.4v battery - NOT the
6-cell, 7.2v battery found in most convenience stores. The 6-cell NiCad is
NOT recommended for use with ProtoSound® applications. 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.

PASSENGER ANNOUNCEMENTS (PFA)
ProtoSounds is now equipped with operator controlled passenger station
announcements, hereby known as PFA. This easy to use feature plays
digitally reproduced passenger station sounds whenever your engine stops
at a train station on your layout. 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 the PFA feature 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 PFA
sequence is designed to simulate the arrival, disembarking, embarking, and
departure of a train entering and leaving a train station. The sounds include
public address arrival and departure messages, passenger disembarking and
embarking sounds, conductor voices and general train station ambient
sounds. Each is described in more detail in the following sections.
ACTIVATING PASSENGER SOUNDS
Your ProtoSounds equipped engine features an operator controlled
passenger station sound set. Once activated, this easy to use feature plays
digitally reproduced sounds of a passenger station whenever you stop your
engine in the neutral position at a train station on your layout.
ARMING THE PASSENGER SOUNDS FEATURE
Before the passenger station 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

horn blast after three seconds have passed at which time you can release the
bell button. (Note: because the horn blast may be 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 passenger sound 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 a horn blast after three seconds have passed at which time
you can release the whistle button. (

ACTIVATING AND TRIGGERING PASSENGER
STATION ANNOUNCEMENTS
Before PFA 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 Passenger Station Sounds
section found earlier on page 8.
Once the feature is activated, PFA will be played the next time the engine
enters the neutral position.In order for PFA 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 DCRU reverse unit functions by disabling the
reverse unit state during operation of the PFA feature. This forces the
engine to leave your station in the same direction it arrived. The following
operator controlled “events” control PFA’s actions and sounds.
Event1 (Forward) While the locomotive is running in forward (or
reverse) PFA 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 PFA.
Event2 (Neutral 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
squealing brakes as the engine comes to a stop.
I. Upon stopping of the engine, the operator must immediately turns
the throttle back on as the engine sits in
neutral. If the bell was not turned off
after activating PFA, it now turns off
automatically.

Note: Failure to turn the throttle
back on within 3 seconds of leaving the
forward phase will disable PFA and

current operating session). Immediately
following the arrival message, the sound
of the trains’ doors opening can be heard,
followed by a conductor’s warning to
passengers to “watch your step.” At this
point, various randomly activated ambient train stations sounds will
begin playing and replaying as long as the engine sits in this neutral
state (Neutral Before Reverse). The sounds include passenger
footsteps as they disembark, muffled voices, baggage being moved
about, crashing sound, and whistling for a taxi. In addition, several
highlight or foreground sounds play including more conductor voices
saying “watch your step”, “have a nice day”, and “baggage to the
right”.

Event 5. (Forward) The operator now interrupts the transformer
throttle again to enter the next reverse unit phase; forward. PFA confirms
to the operator that it has entered the forward phase by playing a conductor
voice yelling “All Aboard!” Immediately after playing “all aboard”, the
sound of the doors closing is heard. Within two seconds of the doors
closing, the locomotive bell begins chiming and the air compressor pumps
start. After approximately 7 chimes of the bell, the engine automatically
begins moving out in the forward phase with the bell continuing to ring
another 7 chimes before automatically turning off. Once the bell turns off
the operator regains control of the transformer whistle and bell buttons and
can ring the bell or blow the whistle as usual.
Note: When entering the forward phase of PFA, it is important to set the
transformer throttle at a high enough setting that will allow the engine to
begin moving once PFA automatically activates the motors. Otherwise, the
engine will just sit still until you increase the throttle setting on the
transformer.
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 33. 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

may not hear the air-release sounds) and the computer will still remember
the number of 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 5, 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 HORN IN NEUTRAL
OPERATION
If you are operating your engine with a separate bell button and want to
blow your horn when your engine is in neutral, you will need to program
ProtoSounds to do so as the factory setting only allows the horn to blow in
forward or reverse. To do this, enter RESET and go to Feature 25. (See the
section Using RESET ToProgram ProtoSounds® on
page 17.) Once in Feature 25,
press the transformer whistle
button and wait for
ProtoSounds to sound a bell

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

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

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
23. To turn off the Cab Chatter sounds, enter RESET and go to Feature 23.

REVERSE UNIT LOCK-OUT OPERATION
ProtoSound’s 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

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.
Use light household oil and follow the lubrication points marked “L" in Fig.
7 below.
Figure7:LubricatingTheTruck
The locomotive’s internal gearing in both power trucks has been greased at
the factory and shouldn’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 six Phillips screws. The screws are located on each end of the
chassis’ as seen in Fig. 9 on the following page. After removing the screws,
lift the body away from the chassis and lay the body next to the chassis.
Figure8:GreasingThePowerTrucks
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. 8).
PREMIER LINE
MTH GG-1 Operating Manual
26
Once the motor mount screw has been removed, pull the motor away from
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. 7. above 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
PREMIER LINE
MTH GG-1 Operating Manual
27
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
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 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 GG-1 locomotive’s headlights are controlled by constant voltage
circuits inside the locomotive body. The headlight(s) can be easily removed
from their lampholders should the bulbs expire. To remove the bulb, follow
the body removal instructions found in the Lubrication section on the
proceeding pages. Once the cab has been separated from the chassis, gently
unplug the bulb’s wiring harness from the socket on the constant voltage
circuit. Replacement bulbs are available directly from MTH Electric
Trains.

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 ProtoSound’s sound effects. The operator retains
control over the engine, but no sound effects will play.
While the MTH GG-1 diesel is more than capable of operating on O-72
curves and switches, you may find that certain light freight cars are prone to
derailing when being pulled or pushed by the MTH GG-1 through O-72
switches. Should this occur, we suggest adding weight to the cars making
them heavier and less likely to derail.
WARNING:
When using electrical products, basic safety precautions should be
followed including the following:
-- Read this and all related manuals (transformer/power supply,
locomotive, etc.) thoroughly before using this device.
-- This device is not recommended for children under eight years of age
without adult supervision.
-- MTH recommends parents examine the toy transformer used to power
this device periodically for conditions that may result in the risk of fire,
electric shock, or injury to persons, such as damage to the primary or output
cord, plug blades, housing or other parts (including proper functioning of
the circuit breaker), and that, in an event such conditions exist, the
transformer should not be used until properly repaired.
