ongratulations! You now own one

of the most sophisticated model
trains ever built—the Lionel
TrainMaster Command-equipped
“Geep” diesel locomotive.

From the crisp detail and expert
decoration on the outside to the
advanced technology and brute power

under its hood, your Lionel “Geep” is
ready for duty on your model railroad.

Read this instruction manual thor­oughly for important tips on operat­ing and maintaining your “Geep”
locomotive. When properly cared for,
it will last a lifetime. Experience the
superiority of today’s Lionel.

Running your “Geep” with a Lionel transformer

Place your “Geep” locomotive on Lionel or Lionel­compatible O gauge track.

• Note the pull of Magne-Traction between your “Geep” and the
steel track. Magnetized wheels and axles increase your pulling
power (more than 25 cars on straight and level track) and keep
your “Geep” on track while passing swiftly through curves.

Power up your “Geep” with your transformer.

• Your “Geep” is designed to operate on 7-18 volts alternating cur­rent. Virtually all Lionel and Lionel-compatible alternating-current

transformers are suitable; we recommend the TrainMaster
Command model railroad control system.

• D

O NOT POWER YOUR

“GEEP” WITH DIRECT CURRENT

(DC). Damage

to sensitive electronic components may occur.

• When you first power up your track, the “Geep” will wait
between 3 and 8 seconds as it “listens” for digital language from
the TrainMaster Command Base (available separately). When it’s
determined that it’s on a conventional (nonCommand) railroad,
the “Geep”’s headlights will illuminate and Railsounds will fire
up. At this point, the locomotive is in neutral. (This occurs when
placing the “Geep” on your railroad for the first time. Thereafter,
it starts in forward after every three-second power interrupt.)

Note!

Move ‘em out!

• Get your “Geep” moving. Press the DIR button on your CAB-1
remote or Lionel transformer. This sequences the Lionel
Command reverse unit (R2LC) to the next operating state. The
R2LC alternates between three states: forward, neutral, and
reverse.

• Adjust track voltage until your “Geep” moves at your desired
speed. To increase speed, increase track voltage. To decrease
speed, reduce voltage. To stop the locomotive, cut track power.

• To select a single operating state (example: forward only), you
can deactivate the R2LC’s sequencing function. Get your “Geep”
moving in the desired direction, then slide the reverse unit control
switch on the locomotive’s underside to PROGRAM. See page 12
for the switch location and positioning.

Using your “Geep”’s Electrocoupler in the non-Command environment

Y

our “Geep” is equipped with front

and rear Electrocouplers. When in
the non-Command environment, you
must first couple a piece of rolling stock

equipped with Lionel magnetic cou­plers directly to your “Geep”. The mag­netic coupler on the rolling stock will
then react to the magnetic field generat­ed by a Lionel remote-control track sec­tion (available separately). Place your
rolling stock’s coupler “trigger disc”
over the central coil of a remote-control
track section and press uncouple on the
controller. The magnetic field pulls the
disc downward, and the coupler opens.

Your “Geep”s Electrocouplers will NOT
open manually or by using a remote-con­trol track section

our Lionel “Geep” is equipped

with front and rear
Electrocouplers and it will
respond to the C

OUPLER F (front)

and C

OUPLER R (rear) button on

your CAB-1 remote when operat­ed in the Trainmaster Command

environment. Simply press either but-

ton on your CAB-1 remote, and
that coupler opens.

Your”Geep”’s
Electrocoupler are

NOT designed to be

opened manually.

Note!

L

ionel Railsounds is the most realistic
model railroad sound system in the

world. Your “Geep” features digitally
recorded sounds for the ultimate in
authentic sounds.

Begin by

installing a 9­volt alkaline
battery. This
ensures
interuption
free operation
of Railsounds.
Remove the
four cab
mounting
screws (see the
illustration on
page 13 for
their location),
lift off the
“Geep”’s body.
Connect the 9­volt battery to
the battery clip and place the battery into
the holder. Replace the body and reinsert
the four screws.

Apply track power and the
“Geep’s”Railsounds system delivers an
authentic start-up sequence, followed by
sounds of the locomotive at idle. As the
“Geep”’s speed increases, the RPMs move

through four lev­els of roar. Sounds
return to idle only
after the locomo­tive has come to a
complete halt. To
silence diesel
RPM roar (horn
and bell remain
unaffected), slide
the Railsounds
switch to its SIG­NAL position

before powering up

the locomotive. See

page 12 for the
switch location
and positioning.
To return to the

diesel RPM roar, return the switch to the
FULL position before powering up the loco-

motive.

Note!

Note!

Note!

Discontinue locomotive power for
10 seconds before changing the
Railsounds on/off switch.

If Railsounds “drops out” during
track power interrupts, replace the
battery.

Although track voltage powers
Railsounds, the battery is required
for uninterrupted operation and
shutdown sequences. Use only
alkaline

batteries; do not use

“heavy duty” batteries.

Install a 9-volt alkaline battery in your “Geep”. Remove the
four mounting screws, lift off the body, connect the battery to
the power cord, and place the battery into the holder.

A note on Magne-Traction

Y

our “Geep” is equipped with

Lionel Magne-Traction, magne­tized wheelsets and axles that help
increase tractive effort during opera­tion. Because the wheelsets are mag­netized, take care to prevent small

metallic objects from attaching to the
wheel sets and working their way
into the “Geep”’s motor assembly.
They can damage your locomotive.

Magne-Traction is not effective
on nonferrous track.
