Lionel 2338 User manual

Lionel No. 2338 GP-7 Locomotive is a replica of the GP-7 locomotive used by Milwaukee
Road for passenger service.
Lionel’s GP-7 Locomotive is built to run on either “O” or O27” track. The GP-7 is powered
by a single worm-drive motor driving two magne-traction axles which enable it to pull a
long string of passenger cars. The operating voltage of this locomotive is from 8 to 18 volts
depending on the train load.
LIONEL “MAGNE-TRACTION”
This locomotive is equipped with “Magne-Traction” which means that its driving wheels are
magnetized by powerful Alnico magnets inserted in the driving axles in order to grip the track
and enable the locomotive to pull heavier loads and climb steeper grades without slipping
on the track. Be careful not to let pins, paperclips, carpet tacks or other small iron objects
come in contact with the locomotive or they will be attracted to the wheels, gears, or axles
and interfere with the action of the locomotive. NOTE: “Magne-Traction” is not effective on
aluminum, brass or other non-magnetic rails. The locomotive also includes two traction tires,
which will improve traction on both magnetic and non-magnetic rails.

RUNNING yOUR LOCOMOTIVE wITh A LIONEL TRANSFORMER
Transformer operations
Caution! Do not power your locomotive with direct current (DC).
Damage to sensitive electronic components may occur.
PLACE yOUR TRAIN SET ON LIONEL OR LIONEL-COMPATIBLE O
GAUGE TRACK.
ThROTTLE UP yOUR LOCOMOTIVE wITh yOUR
TRANSFORMER.
Your locomotive is designed to operate on 8-18 volts
alternating current. Virtually all Lionel and Lionel-compatible
alternating current transformers are suitable.
Throttle up your locomotive and it will begin to move in the forward
direction. Adjust track voltage until your locomotive moves at your desired
speed. To increase speed, increase track voltage. To decrease speed, decrease
voltage.
Pressing the DIRECTION button on your transformer will sequence the
Electronic E-unit to the next operating state in the repeating sequence of:
forward, neutral, reverse, neutral, and so on.
To stop the locomotive, cycle the Electronic E-unit to neutral or turn-off
track power.

LOCKING yOUR LOCOMOTIVE INTO FORwARD DIRECTION ONLy OPERATION
When the Electronic E-unit Direction Lock switch is in the RUN position, your locomotive
sequences through a repeating pattern of operations: forward, neutral, reverse, neutral, and so
on.
To lock your locomotive into forward direction only operation, you can deactivate the
Electronic E-unit’s sequencing function. Follow the steps below and refer to figure 1 for the
location of the Electronic E-unit Direction Lock switch.
Always turn off track power before removing the locomotive from the track.
1. Turn off track power, wait three seconds, and remove the locomotive from the track. Now
slide the Electronic E-unit Direction Lock switch to the LOCK position. Your locomotive is
now locked into forward direction only operation.
2. Place your locomotive back on the track. Power up the track and press the direction button
on your transformer to confirm that the locomotive is now locked into forward direction
only operation.
To restore the forward-neutral-reverse sequence, turn off power and remove your locomotive
from the track. Slide the Electronic E-unit Direction Lock switch back to the RUN position.
Place the locomotive back on the track and restore track power.

Transformer operations
Your Lionel locomotive is equipped with operating magnetic knuckle couplers, a
revolutionary design first introduced by Lionel in 1945.
Lionel magnetic couplers react to the magnetic field generated by a Lionel Remote-Control
Track section (available separately, 6-65149 or 6-12746 for O-27 gauge; 6-65530 for O gauge;
or 6-12020 and 6-12054 for FasTrack layouts).
Place your locomotive’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 knuckle opens.
One operating technique favored by Lionel railroaders is the “moving uncouple.” Press
the UNCOUPLE button as the locomotive passes over a Remote-Control Track section. The
magnetic field will open the coupler; the consist remains behind as the locomotive moves
on. But be careful—the speed of a newly uncoupled and moving locomotive can increase
dramatically.

SOUNDING yOUR LOCOMOTIVE’S ELECTRONIC hORN AND BELL
Use the HORN and BELL buttons on your transformer to activate the locomotives horn and
bell sounds.
If your transformer lacks HORN and BELL buttons, you will need to install Lionel
no. 610-5906-001 Sound Activation Buttons (available separately) to activate the locomotive’s
horn and bell sounds.
Connect the buttons as shown below. Be sure that all track power passes through the Sound
Activation Button(s).

Operating and servicing your locomotive
SERVICE INFORMATION
The life and performance of the locomotive depends to a considerable extent upon proper
care and lubrication of the motor and other moving parts. Since your locomotive might have
been stored on the dealer’s shelves for some time, be sure to lubricate it according to the
lubrication chart in Figure 4 on page 8 before running it for the first time. Put a small dab of
Lionel Lubricant at all points marked “L”. Using the point of a pin or a thin wire, put a drop
of Lionel Oil at points marked “O”. Lubricate carefully but never to excess. A small amount of
oil or lubricant, properly applied, goes a long way. Be careful not to get any oil or lubricant on
the running surfaces of the wheels or on the rails, or your locomotive will lose traction and do
not lubricate locomotive rollers.
The motors of this locomotive require occasional lubrication with a few drops of light
machine oil. See Figure 5 on page 9. To get at the motors the locomotive body must first be
removed by removing the screws in the ends of the locomotive.
A complete Lubrication and Maintenance Kit No. 927 (6-62927) which contains all the
material and equipment necessary to keep your outfit in top notch condition may be obtained
from your authorized Lionel dealer or service station.
This locomotive has front and rear headlights which are illuminated by 14 volt, bayonet-
base lamps (No. 600-0363-300), available at your authorized Lionel dealer or service station.
To replace your lamps, see the instructions on page 10.

Operating and servicing your locomotive
LUBRICATING yOUR LOCOMOTIVE
Help your Lionel locomotive lead a long and productive life on your railroad by maintaining it
properly. To keep your locomotive lubricated, we recommend that you purchase a Lionel Lubrication
and Maintenance Kit (6-62927), available from your authorized Lionel dealer or service station.
When you find that the lubrication points illustrated in Figure 3 appear dry, lubricate your
locomotive after you have removed any accumulated dirt and dust. There are two basic rules to keep
in mind when you are lubricating your locomotive: use only a small amount of lubrication and avoid
getting grease or oil on your locomotive’s wheels, roller pick-ups, or the track.

Your locomotive will require occasional lubrication of its Pullmor motor armatures. If you
hear excess noise during operation, or if the locomotive slows down intermittently, you may
need to oil the top armature bearings.
1. Remove the locomotive’s body mounting screws from both ends of the body. Carefully lift
the shell away from the frame.
2. Apply a small amount of Lionel oil (two drops) in the hole at the top of each motor. See
Figure 4.
3. Replace the body, securing it with the two body mounting screws.
To prevent damage to the locomotive body, do not overtighten the body screws.

REPLACING yOUR LOCOMOTIVE’S LAMPS
Your locomotive is illuminated by two 14-volt lamps. During the course of normal
operations, they may require replacement
1. Remove the locomotive’s body mounting screws from both ends of the body. Carefully lift
the shell away from the frame.
2. To remove the lamp, gentley push the lamp down and turn counter counter clockwise to
disengage the lamp from the socket
3. Replace it with Lionel part no. 600-0363-300, available from your authorized Lionel dealer
or service station, or from Lionel Customer Service in Chesterfield, MI. See Instructions
for Obtaining Service on page 12 for more information.
4. Replace the body, securing it with the two body screws.
To prevent damage to the locomotive body, do not overtighten the body screws.
