PREMIER GP-7
DIESEL ENGINE
OPERATING INSTRUCTIONS
This GP-7 Diesel Engine features a detailed ABS body, die-cast trucks and runs on O-31
curves.
This Premier Diesel 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
that is equipped with whistle and bell buttons (see the compatibility chart on page
20),
and is 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.

Premier GP-7 Diesel Engine Operating Instructions
SetUp
There are a couple of simple steps you must take before operating this Premier
diesel.
1. 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.
7 on pg. 13 ) with lithium-based grease to
prevent them from squeaking and premature wear. Use light household oil and
follow the lubrication points (marked “L” in Fig.
5 on pg. 12). Do not
over-oil. Use only a drop or two on each pivot point.
2. Prime the operating smoke unit with smoke fluid before operating. Add
15-20 drops of smoke fluid through the smokestack (see Fig.
2 on pg. 10), then
gently blow into the stack to eliminate any air bubbles in the fluid.
3. If you choose not to prime the unit with fluid, turn the smoke unit switch
located under the engine to the OFF position (see Fig. 3 on pg. 10
). Running
the engine without a primed smoke unit may cause damage. See the
“ProtoSmoke Unit Operation” section of this book for more information on
smoke unit maintenance.
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. Give about 10-12 volts or
enough power so that the engine’s headlight shines brightly. Then put the
engine into motion by either firmly pressing the Direction button on your
transformer or remote once or 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.
Manual 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).

Proto-Sound 2.0 Operating Instructions
This manual contains the operating instructions for Proto-Sound 2.0 in
conventional mode only. Instructions for accessing DCS command mode
features accompany the DCS Remote Control System equipment.
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.

Freight Yard Sounds (FYS):
Your engine is equipped with a sound package of freight yard sounds that you
can play when you pull into a yard. Each sequence described below will
play as long as it is left on, randomly generating sounds, but be sure to
allow approximately 30 seconds between the button pushes described
below to allow the FYS sufficient time to run through each sequence.
1. To cue the sound system to play the FYS, quickly but firmly tap the Bell
button once followed by 2 quick taps of the Whistle button while the engine is
moving. Tap the buttons quickly but allow approximately ½ second between
each press.
2. Press the Direction button or drop and advance the throttle once to stop the
engine. This will trigger the first sequence of FYS. 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 FYS sequence is complete.
3. After waiting about 30 seconds for that sequence to run, press the Direction
button again to trigger the second sequence of FYS.
4. After about 30 seconds, press the Direction button again to trigger the third
FYS sequence.
5. Again, after allowing about 30 seconds for that sequence to run, press the
Direction button one more time to trigger the fourth and final FYS sequence.
The FYS will continue, 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 with the bell ringing. 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.

Tips on Using FYS
• You can terminate FYS at anytime by turning off power to the
track for 15 seconds.
• You do not have to be in Forward to use FYS. 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 FYS even if you are double-heading with another
engine. If the second engine is not equipped with FYS at all, you
must remember not to leave the throttle at a high voltage level once
you have stopped the engine to run the FYS. Otherwise, the engine
without FYS will begin vibrating on the track as its motors strain to
move the train, since they cannot be automatically disabled during
the FYS cycle. If the second engine is an original Proto-Sound
engine equipped with FYS, you may choose to disable it when used
in double-heading operations, so you will not experience
competing FYS sounds. To disable FYS in an original
Proto-Sound engine, see the operating instructions for that engine.
• FYS can be triggered from Neutral. It will operate the same as if
triggered while in motion except that, at the conclusion of the FYS,
the engine will depart in the next direction of travel, as opposed to
the direction it was traveling before entering Neutral.

Proto-Coupler® Operation
This locomotive is equipped with two coil-wound Proto-Couplers 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 tap the Bell button once followed by three
quick taps of the Whistle button, allowing approximately ½ second to lapse
between each quick button press. 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 tap the Bell button once followed by four
quick taps of the Whistle button, allowing approximately ½ second to lapse
between each quick button press. 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, thenquickly tap
the transformer’s Whistle button one time then quickly tap the Bell button two
times, allowing approximately ½ second to lapse between each quick button
press. Two horn blasts will indicate that the engine has made the change.
Repeat the 1 whistle, 2 bells code to return it to the other condition. 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. Note: When
speed control is turned off, the Proto-Sound 2.0 system will limit the volume
in order to operate more smoothly at lower voltages. Full volume is restored
upon reactivating speed control.

Lock into a Direction:
You can lock your engine into a direction (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 neutral), run it at a very slow crawl (as
slowly as it will move without halting), and quickly but firmly tap the Horn
button once followed by three quick taps of the Bell button, allowing
approximately ½ second to lapse between each quick button press.
Two horn
blasts will indicate that the engine has made the change.
The engine will not
change direction (including going into neutral) until you repeat the 1 horn, 3
bells code to return the engine to its normal condition, even if the engine is
kept without power for extended periods of time.
Reset to Factory Defaults:
To override the settings you currently have assigned to the engine and reset it
to its factory defaults, while in Neutral tap the Whistle button quickly once,
followed by five quick taps of the Bell button, allowing approximately ½
second to lapse between each quick button press.
Two horn blasts will indicate
that the engine has made the change.
Automatic Sounds:
Certain Proto-Sound 2.0 sound effects automatically play in programmed
conventional mode conditions:
Squealing Brakes
play when the engine’s speed is decreased rapidly.
Cab Chatter
plays when the engine idles in neutral.
Engine Start-up and Shut-down
sounds play when the engine is initially
powered on or is powered off for five seconds or more.

Maintenance
ProtoSmoke®UnitOperation
This Premier diesel locomotive contains a self-powered smoke unit that outputs
smoke through the smokestack on the roof of the engine. The smoke unit is
essentially a small heating element and wick that soaks up and then heats a
mineral oil-based fluid that emits a harmless smoke. The smoke is then forced
out of the stack by a small electric fan. Smoke volume is controlled by the
Proto-Sound 2.0 system.
With a few easy maintenance steps, you
should enjoy trouble-free smoke unit
operation for years.
When preparing to run this engine, add
15-20 drops of smoke fluid through the
smokestack (see Fig.2). We recommend
M.T.H. ProtoSmoke, Seuthe, LGB, or
LVTS fluids. Do not overfill the unit or
the fluid may leak out and coat the interior
engine components.
If you choose not to add the fluid (or have
already added the fluid but choose to run
smoke-free), turn off the smoke unit switch
located under the engine (see Fig. 3).
Failure either to add fluid to the unit or to
turn it off may damage the smoke unit
heating element and/or wicking material.
When the smoke output while running the
engine begins to diminish, add another
10-15 drops of smoke fluid or turn the
smoke unit off.
When storing the unit for long periods of time, you may want to add about 15
drops of fluid to prevent the wick from drying out.
