RAILKING GG-1
ELECTRIC ENGINE
OPERATING
INSTRUCTIONS
Thank you for purchasing the RailKing GG-1 Electric Engine. This RailKing Electric
Engine contains state-of-the-art electronics with many built-in automatic features for
incredibly realistic operation. Despite these advanced features, the locomotive is easy to
operate with any compatible standard AC transformer (see the compatibility chart on
page 18), and is completely compatible with most other 3-rail locomotives, rolling stock,
and accessories.
This locomotive is equipped with Proto-Sound 2.0 with Digital Command System
(DCS). This new system will allow you to operate your locomotive in Command mode
(when used with the DCS Remote Control System, sold separately) or Conventional
mode. Conventional operating features are described in the following pages, while the
DCS operating features are covered in the set of operating instructions that accompanies
the DCS equipment. Conventional Mode operation of this locomotive is much simpler
than operation of original Proto-Sound engines. For your own safety and that of your
equipment, please read the instructions before you operate this engine.

INITIAL LUBRICATION
Although the engine was lubricated at the factory, it is important that you
lubricate the chassis before operation. Lightly grease the outside idler and
drive gears (marked “G” in Fig. 3 on page 10) to prevent them from squeaking.
Use light household oil and follow the lubrication points marked “L” in Fig. 2
on page 9. Do not over-oil. Use only a drop or two on each pivot point.
At this point, you are ready to put your engine on the track and begin running
it.
BASIC OPERATION
Throttle – Throttle up the power to your track by either firmly pressing the
Direction button on your transformer or remote once or quickly dropping and
advancing the throttle to put the engine in forward.
Operation Buttons
Use the operation buttons on your transformer or remote as described below.
Horn/Whistle - To sound the horn, firmly press the Horn/Whistle button. The
horn will sound for as long as you continue to depress the button. It will stop
when you release the button.
Bell - To sound the bell, firmly press and release the Bell button. To turn the
bell off, press and release the Bell button again. The bell will continue to ring
from the time your turn it on until you press and release the button again to
turn it off.
Direction – Your train is programmed to start in neutral. To put the engine
into forward and then to change the direction of the train or to put it into
neutral, firmly press and release the Direction button on your transformer. Just
as you must stop your car between forward and reverse, this engine will not go
directly from forward to reverse; it goes into neutral between directions. If the
train has been moving forward, the first press of the Direction button will put
the train from forward into neutral, the second press into reverse, the third
press back into neutral, and the fourth back into forward. To prevent accidental
high-speed start-ups, this engine is programmed to restart in neutral each time
the track voltage is turned off for 10 seconds or more.

PROTO-SOUND
2.0 OPERATING INSTRUCTIONS
Because Proto-Sound 2.0 is an all-new system developed by M.T.H.’s own
research and development team, it operates differently from original
Proto-Sound. Most Proto-Sound 2.0 features are automatically enabled, and the
reset state has been eliminated, so there is no need to program features as with
original Proto-Sound. Although the new system is easier to operate than
original Proto-Sound, you should read these instructions thoroughly before
using Proto-Sound 2.0 features in order to prevent harm to yourself or your
equipment.
Activating Proto-Sound 2.0 Conventional Mode Features:
Proto-Sound 2.0 features are activated by sequences of Bell and Whistle button
pushes described below. Please read the full descriptions of each feature
before using it. To use these buttons to activate features rather than to blow the
whistle or ring the bell, you should press the buttons for a shorter time (1/2
second); you may need to practice your timing to make this work smoothly.
Volume Control –To adjust the volume of all sounds made by this engine,
turn the master volume control knob located under the engine clockwise to
increase the volume and counter-clockwise to decrease the volume (see Fig. 1).

Passenger Station Announcements (PSA):
Your engine is equipped with a sound package of passenger station
announcements that you can play when you pull into a passenger station.
Each sequence described below will play as long as it is left on, randomly
generating sounds, but be sure to allow time between the button pushes
described below to allow the PSAs sufficient time to run through each
sequence.
1. To cue the sound system to play the PSA, quickly but firmly press the Bell
button once followed by 2 quick presses of the Whistle button while the engine
is moving. As soon as you have keyed in this code, you will hear the
announcement for the upcoming stop and the bell will begin to ring.
2. Press the Direction button or drop and advance the throttle once to stop the
engine. This will trigger the first sequence of PSAs. The reverse unit is
temporarily disabled so that the train will not move as you use the Direction
button to trigger the sounds, and Proto-Sound 2.0 has disabled operator control
over the Whistle and Bell buttons until the full PSA sequence is complete.
You will hear (what?)
3. After waiting at least a few seconds for that sequence to run, press the
Direction button again to trigger the second sequence of PSAs. You will hear
(what?)
4. After at least another few seconds, press the Direction button again to
trigger the third PSA sequence. You will hear (what?)
5. Again, after allowing at least a few seconds for that sequence to run, press
the Direction button one more time to trigger the fourth and final PSA
sequence. You will know it is the final sequence when you hear the “All
Aboard!” call. The bell will begin to chime and within a few seconds, the
engine will start and move out on its own at the current throttle setting, in the
same direction it was traveling when you began the sequence. Once the bell
turns off, the operator regains control of the transformer’s bell and whistle
buttons and can ring the bell or blow the whistle as usual.

6
RailKing GG-1 Electric Engine
Tips on Using PSAs
You can terminate PSA at anytime by turning off power to the
track for 15 seconds.
You do not have to be in Forward to use PSA. At the conclusion
of the full sequence, the train will pull away from the station in
whatever direction you were going when you activated the
feature.
You can use PSA even if you are double-heading with another
engine regardless of whether the second engine is equipped with
a Proto-Sound 2.0 PSA module. If the second engine is not
equipped with PSAs at all, you must remember not to leave the
throttle at a high voltage level once you have stopped the engine
to run the PSAs. Otherwise, the engine without PSAs will begin
vibrating on the track as its motors strain to move the train, since
they cannot be automatically disabled during the PSA cycle. If
the second engine (whether original Proto-Sound or Proto-Sound
2.0) is equipped with PSAs, you may choose to disable it when
used in double-heading operations, so you will not experience
competing PSA sounds. To disable PSAs in an original
Proto-Sound engine, see the operating instructions for that
engine.

RailKing GG-1 Electric Engine
Proto-Coupler® Operation
This locomotive is equipped with a coil-wound Proto-Coupler for remote
uncoupling action. Because the Proto-Coupler is controlled through the
Proto-Sound 2.0 microprocessor, it does not require an uncoupling track section
or modification to your layout to function. Use the codes listed below to fire
the coupler.
Rear Coupler:
To fire the rear coupler, quickly press the Bell button once followed
immediately by three pushes of the Whistle button. The sound of the liftbar
and air line depletion will play, and the knuckle will be released.
Front Coupler:
To fire the front coupler, quickly press the Bell button once followed
immediately by four pushes of the Whistle button. The sound of the liftbar and
air line depletion will play, and the knuckle will be released.
Speed Control:
M.T.H. engines equipped with Proto-Sound 2.0 have speed control capabilities
that allow the engine to maintain a constant speed up and down grades and
around curves, much like an automobile cruise control. You can add or drop
cars on the run, and the engine will maintain the speed you set.
While the engine is programmed to start with the speed control feature
activated, you can opt to turn it off. This means the engine’s speed will fall as
it labors up a hill and increase as it travels downward. It is also affected by the
addition or releasing of cars while on the run.
To turn speed control on and off, put the engine in neutral, then press the
transformer’s Whistle button firmly but quickly one time then immediately
press the Bell button two times. Repeat the 1 whistle, 2 bells code to return it
to the other state. You will want to do this during the initial neutral upon
start-up if you ever couple this engine to another engine that is not equipped
with speed control to avoid damaging the motors in either engine. Each time
you shut down the engine completely, it will automatically turn speed control
on.

8
RailKing GG-1 Electric Engine
Lock into a Directional State:
You can lock your engine into a directional state (forward, neutral, or reverse)
so that it will not change directions. To do this, put the engine into the
direction you want or into neutral. To lock it into forward or reverse, run it at
a very slow speed (< 10 scale mph), and quickly but firmly press your
remote’s Whistle button once followed immediately by three presses of the
Bell button. The engine will not change direction (including going into
neutral) until you repeat the 1 whistle, 3 bells code to return the engine to its
normal state.To lock your engine into neutral, place engine in neutral and set
the track voltage to less than 10v. Then use the same 1 whistle, 3 bell code
to lock and unlock your engine from neutral.
Reset to Factory Defaults:
To override the settings you currently have assigned to the engine and reset it
to its factory defaults, quickly press the Whistle button once, followed
immediately by five quick pushes of the Bell button.
Automatic Sounds:
Certain Proto-Sound 2.0 sound effects automatically play in programmed
conventional mode conditions:
Squealing Brakesplay when the engine’s speed is decreased by 50% +5 scale
MPH.
Cab Chatterplays when the engine idles in neutral.
Engine Start-up and Shut-downsounds play when the engine starts up and
shuts down.

MAINTENANCE
Lubrication and Greasing Instructions
The engine should be well oiled and greased in order to run properly.
You should regularly lubricate the pickup rollers to prevent them from
squeaking. Use light household oil and follow the lubrication points marked
“L” in Fig. 2. Do not over oil. Use only a drop or two on each pivot point.
The locomotive’s internal gearing was greased at the factory and should not
need additional grease until after 50 hours of operation or one year, whichever
comes first. Follow the greasing instructions below. Note that in some tightly
packed engines you may need to move internal components temporarily in
order to access the gears.
1. Remove the screws from the chassis, as seen in Figure 3 on page 10, then
lift the body away from the chassis.
2. After removing the body shell, turn your engine upside down and remove
the two Phillips screws holding the pick-up roller to its truck. Lift pick-up
roller and unplug the wire.
3. Remove the single flathead screw in the adjacent pilot/trailing truck.
4. Remove the single Phillips screw that was hidden by the pick-up roller
before you removed it. Lift off the truck block and turn it over.
5. Remove the four Phillips screws from the truck block and pull apart.

6. 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.
7. Reassemble the truck and motor, being careful not to pinch any wires
between the truck block and motor mount.
8. Repeat the procedure for the other motor and truck
9. Reassemble the chassis and body, being careful that the wires are not caught
between the body and chassis, as this can lead to a short that may damage the
electronics beyond repair.
It is also a good idea to lubricate the outside truck block idler and drive gears
with grease occasionally. Add grease to the points marked with “G” in Figure
3.
Cleaning the Wheels, Tires and Track
Periodically check the locomotive wheels and pickups for dirt and buildup,
which can cause poor electrical contact and traction as well as prematurely
wear out the neoprene traction tires. Wheels and tires can be cleaned using
denatured alcohol (not rubbing alcohol), which can be found in home
improvement stores, applied with a cotton swab.
Occasional cleaning of the track will also help to ensure good electrical contact
and to prolong the life of your engine’s tires. To clean the track, use a clean
rag and denatured alcohol (not rubbing alcohol). Unplug the transformer and
wipe the rails of the track, turning the rag frequently to ensure that you are
using clean cloth on the rails.

Traction Tire Replacement Instructions
Your locomotive is equipped with two neoprene rubber traction tires on each
powered truck block. While these tires are extremely durable, you may need to
replace them at some point.
Replace the tires on only one end of the engine at a time.
To disassemble:
1. Remove the screws from the chassis, as seen in Figure 3 on page 10, then
lift the body away from the chassis.
2. After removing the body shell, turn your engine upside down and remove
the two Phillips screws holding the pick-up roller to its truck. Lift pick-up
roller and unplug the wire.
3. Remove the single flathead screw in the adjacent pilot/trailing truck.
4. Remove the single Phillips screw that was hidden by the pick-up roller
before you removed it. Lift off the truck block and turn it over.
5. Remove the four Phillips screws from the truck block and pull apart.

To replace the tire:
1. Make sure the old tire has been completely removed from the groove in the
drive wheel, using a razor blade or small flathead screwdriver to pry away any
remains.
2. Slip the new tire onto the wheel. You may find it useful to use two small
flathead screwdrivers to stretch the tire over the wheel.
3. If you twist the tire while stretching it over the wheel, you will need to
remove and reinstall the tire. Otherwise your engine will wobble while
operating.
4. Make sure the tire is fully seated inside the groove. Use a razor blade to
trim away any excess tire that doesn’t seat itself inside the groove properly.
Reassemble in the reverse order and replace the tires on the other end of the
engine.
One set of replacement tires is packaged with your model. Additional tires are
available directly from the M.T.H. Parts Department (phone: [phone];
fax: [phone]; e-mail: [email protected]; mail: 7020 Columbia
Gateway Drive, Columbia MD 21046-1532).

Self-Charging Battery Back-Up
The special NiCad 7-cell 8.4v self-charging battery in this engine
improves performance at any speed. It ensures that power to the sound system
will remain on during directional changes, or when traveling over dirty track
or switches.
The self-charging battery system is automatically turned on or off whenever
track power is turned on or off.
Track power (when applied) recharges the battery, which should last for up
to five years, and the special NiCad battery is a dry battery that should not leak
or cause any damage to your engine. However, even this special battery will
eventually wear down and need to be replaced. When you notice that your
engine sounds seem distorted or garbled at low voltages or become silent when
power from the transformer is turned off, test the battery to determine whether
it should be recharged or replaced.
Put the engine in neutral and leave the track voltage at 12 volts for 15 minutes
If the garbled or distorted sounds are reduced, the battery charge has run down
and can be recharged. There are three options to recharge the battery. 1. Leave
the engine in neutral with track voltage at 12 volts for 6-7 hours so the battery
can fully recharge (if your engine has a smoke unit, be sure it is turned off).
2. Using M.T.H.’s battery charger (item #50-10005) plug the charger into the
battery port located on the bottom of the tender. (see figure 8) Let it charge for
6-7 hours. 3. Remove the battery (as shown in figure 7, below) and charge it
in any standard slow charge battery recharger, following the recharger’s
directions.
If the sounds are not improved at the end of the 15 minute test charge, the

Sometimes the Cab Chatter sounds
don’t play.
I can’t get the engine to run after I
power up the transformer. It sits still
with the engine sounds running.
The engine won’t lock into forward,
neutral, or reverse.
The sounds seem distorted, especially
when the whistle or bell is activated.
The engine will not leave the initial
neutral setting
The PSA sounds occasionally repeat
themselves.
I get no sounds when the engine shifts
between directions.
After I turn off my transformer, my
engine continues to make sounds
before quitting.
Cab Chatter plays only in neutral.
The engine is locked into the neutral
position. Follow the procedure in the
“Lock into a Direction” section.
Engine speed must be below 10 scale
mph (approx. 10 volts or less in
conventional mode).
Proto-Sound 2.0 volume is set too
high. Turn the volume control knob on
the bottom of the chassis counter-
clockwise to reduce the volume.
Check to be sure the battery is
installed and fully charged. See the
“Self-Charging Battery Back-Up”
section.
The battery may be dead or need to
be charged. See the “Self-Charging
Battery Back-Up” section.
Proto-Sound 2.0 is designed to
continue to sound for a few seconds
after power to the track has been shut
off.
Proto-Sound 2.0 has a built-in random
number generator that randomly
selects each sound clip to play.
Because there are a limited number of
sound clips available in each PSA
sequence, it is probable that some of
these sound clips will be repeated
from time to time.

PSA Remedy
Once in PSA, the engine doesn’t go
into reverse.
When the PSA enters its last
sequence the bell automatically
comeson.
When PSA is enabled, pressing the
whistle and bell buttons has no effect.
I push the direction button but the next
sound clip in the sequence does not
play or the engine does not come out
of PSA after fourth press of the
direction button.
So that PSA effects can be as realistic
as possible, Proto-Sound 2.0
disables the reversing unit
whenever PSA is enabled. This
way the engine remains still at its
stop as the operator cycles
through the PSA sequences.
PSA is programmed to start ringing
the bell at that point. After
approximately 12 rings of the bell, it
will automatically turn off.
Because PSA must control various
effects in each sequence, Proto-
Sound 2.0 takes control of these
sound effects until you exit PSA.
Each PSA clip must play for approx.
30 seconds before PSA will advance
to the next step in the PSA cycle. Wait
at least 30 seconds in each PSA
sound clip before pressing the
direction button.
Compatibility
This engine will operate on any traditional O-31 or larger O Gauge track
system, including M.T.H.’s RealTrax® or ScaleTrax™ or traditional tubular
track. It is also compatible with virtually most standard AC transformers.
(See page 17 for a complete list of compatible transformers and wiring
instructions.)
