QUICK START - BASIC OPERATION
The MTH GP38-2 contains state-of-the art electronics with several built-in
automatic features for incredibly realistic operation. Despite these advanced
features, the GP38-2 is easy to operate with any compatible standard AC
transformer (see the compatibility chart on page 33).
The GP38-2 model 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).

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
DCRU® reverse unit that contains the standard forward-neutral-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
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
4
MTH GP38-2 Diesel Operating Manual
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.
HORN OPERATION
Your GP38-2 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 whistle to work when the engine is in
neutral. See page 20 for information on horn programming in the Using
RESET To Program ProtoSounds® section of this manual.
BELL OPERATION
Your GP38-2 ProtoSound®-equipped engine is equipped with a digital
recording of an actual diesel engine bell. 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 button. If you don’t have a separate bell

MTH GP38-2 Diesel Operating Manual
PREMIER LINE
ProtoSounds® comes with several programmable functions, including
remote Diesel Engine Volume Adjustment, Separate Bell Button Operation
(pre-programmed at the factory), Horn In Neutral Operation,
ProtoCoupler™ On/Off Control, Squeaking Brakes and Passenger Station
or Freight Yard Proto-Effects. 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. Remember though, once power is turned off
for more than 3 seconds, the next time power is applied to the track, your
engine will be back in RESET.
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.
PREMIER LINE
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 GP38-2 ProtoSound®-equipped locomotive is equipped with two
coil-wound ProtoCouplers™ for remote uncoupling action. Because the
ProtoCoupler™ is controlled through ProtoSounds® 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

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 Figure 3: Lubricating The ProtoCouplers

the coupler. If the coupler
continues to open erratically, try lubricating the knuckle with light oil as
indicated in Fig. 3.

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

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.
PREMIER LINE
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
which speeds and voltage settings will 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 squeaking sound plays, but you don’t need to reduce the
transformer throttle to activate the squeaking sounds. To play the squeaking
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.

FREIGHT YARD SOUNDS (FYS)
USING FREIGHT YARD SOUNDS
Your ProtoSound® equipped engine features an operator controlled freight
yard sound set. Once activated, this easy-to-use feature plays the sound of
freight yard activitities whenever the operator parks the engine in the
neutral position.
ARMING THE FREIGHT YARD FEATURE
Before FYS can be heard, ProtoSound® must be told to activate the
feature the next time the engine enters the neutral position. This can be
accomplished in one of two ways.
Option 1: If you are using a separate bell button controller to ring your
bell (like the Lionel® Railsounds® number 5906 bell activation button),
you can activate the feature by pressing and holding down the bell button

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.
carefully, you should hear an air release sound after three seconds have
passed. At this time you can release the bell button. (Note: because the air
release sound may be difficult 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 and allow the engine to begin moving. (Note: the feature will only
be activated in the first direction state you enter after arming 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 moving, you can trigger the sounds to begin playing
whenever you enter Neutral.
PREMIER LINE
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 begin and if you listen
carefully, you should hear an air release sound after three seconds have
passed. At this time you can release the whistle button. (Note: because the
air release sound may be difficult to hear, we recommend that you count out

ACTIVATING THE FREIGHT YARD SOUNDS
Before FYS can be heard, the feature must be armed as described on the
proceeding pages. Once armed, activating the FYS effects is accomplished
by simply interrupting the transformer throttle and parking the engine in the
Neutral position with track power remaining on. Remember, power to the
track must remain on while the engine sits in Neutral in order for the FYS
effects to operate.
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
Put Engine In Neutral

FYS, it now turns off automatically.
Note: Failure to turn the throttle back
on within 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 5 for more information on
RESET.

At this point ProtoSounds® has taken over control of your engine and
disabled the bell and whistle buttons from responding to any futher operator
input. In addition, ProtoSounds® has reconfigured the way the reverse unit
functions by disabling the Reverse state during operation of the FYS
effects. This forces the engine to leave your freight yard in the same
direction that it arrived in. The following operator controlled “events”
control FYS’s actions and sound effects.
B. After entering Neutral, ProtoSounds® will immediately play an
air release sound followed approximately 2 seconds later by a radio
arrival message (cab chatter).

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: You can escape the FYS sequence by interrupting the transformer
throttle before the radio message in Event 2 (neutral before reverse).
Tip #2: You can terminate FYS at anytime by turning the transformer
throttle Off for 15 seconds.
Tip #3: You do not have to be in the Forward phase to utilize FYS. For
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.
13
MTH GP38-2 Diesel Operating Manual
PREMIER LINE
Note: When entering the Forward phase of FYS, it is important to set the transformer
throttle at a high enough setting that will allow the engine to begin moving once FYS
automatically activates the motors. Otherwise the engine will just sit still until you increase
the transformer throttle setting on the transformer. However, don’t set the throttle setting too
high or the engine will go racing away faster than you might expect.
Tip #4: You can utilize FYS even if you are double-heading with another
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 for squeaking brakes and FYS
operation on page 23 of this manual.
PREMIER LINE
Tip #5: It is not necessary for the squeaking brake sounds to be heard to play
the FYS sounds. For example, the brake sounds won’t be heard if the high
voltage setting is below 13 volts when the power is interrupted to enter the
Neutral state.
Tip #6: You can leave any of the event states at any time after entering the
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 radio message 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
ProtoSounds® state-of-the-art design includes a self-recharging battery
backup system for improved performance at any speed. The battery ensures
that power to the sound system will remain on during directional changes,
setting RESET options or when travelling over dirty track and switches.
The self-recharging battery backup system is automatically turned on or off
whenever track power is turned on or are off. There are no switches needed
to enjoy the benefits of the automatic battery backup system.
REPLACING THE PROTOSOUND® BATTERY
The ProtoSound® battery (located inside the cab body), 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. The battery is continually charged from the
track when power is applied and should last for up to five years. In
addition, the NiCad battery is a dry battery and should not leak or cause any
damage to your locomotive during its lifetime.
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

contact MTH for instructions on returning the tender for repair.
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
PREMIER LINE
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. For
information on operating the RESET volume adjustment option, see the
section entitled “Programming ProtoSound RESET Options” on the

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 5. By following the instructions below you will find the
programming easy and straight forward.
ENTERING RESET OPTIONS
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

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.
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.
PREMIER LINE
To access the feature, advance the transformer throttle to put the engine in
RESET. Move the throttle up and down, as described on page 18, 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 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

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® 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 page

may turn on or off sounds of the bell, coupler arming or coupler firing depending on the
transformer throttle voltage settings prior to the user’s attempt to lock out the engine.
Remember, the whistle doesn’t blow in NEUTRAL (unless you programmed it to do so using

The locomotive’s internal gearing 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 can be added by inserting grease into
the gear box inside the locomotive chassis. In order to access the gear box,
the cab must be removed from the chassis by unscrewing the four chassis
screws as seen in Figure 8 on page 28. Once the cab is removed, the trucks
can be removed by unscrewing the truck block/motor mount screw located
on the underside of the drive trucks (See Figure 7). Grease can then be
applied into the gear box using a grease tube dispenser.

TRANSFORMER COMPATIBILITY AND
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® 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-31 OPERATION
While the GP38-2 engine is more than capable of operating on O-31
curves and switches, you may find that certain light freight cars are prone to
derailing when being pulled or pushed by the GP38-2 through O-31
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:
PREMIER LINE
-- Read this and all related manuals (transformer/power supply,
locomotive, etc.) thoroughly before using this device.
-- This device is not recommended for children under ten 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.
