Power your locomotive with an alternating-current (50-60Hz AC) transformer only.
Powering your locomotive with a direct-current (DC) transformer, or in excess of
19 volts AC, may result in damage to sensitive electronic components.
Your locomotive requires Lionel or Lionel-compatible O-36 or larger track curves.
1. Turn off track power, and then plug in the
LEGACY Base and connect it to the track.
2. Place your locomotive on the track.
3. Increase track power voltage to full power
(no more than 19 volts AC). If a circuit breaker
trips when you turn on the Lionel power supply, check
the wheels of your locomotive to make sure they are all
securely on the track. Check to make sure the track is free
of all metals that may cause a short circuit.
4. As illustrated in Figure 1, press ENG and 1
(or your selected ENG ID#) to address the
locomotive with your LEGACY CAB-2 Remote
Controller.
5. Press the Start Up button on your LEGACY
CAB-2 Remote, shown in Figure 2. Then,
throttle up and move 'em out! Your engine sound
will start up, and the locomotive-specific touch screen
buttons will populate the remote. For more information
on operating your locomotive with the LEGACY system,
please refer to the LEGACY section of this manual.
Additional information is also found in the LEGACY
System Manual, available online at www.lionel.com.

LEGACY Control operations
Your locomotive is designed for operation with the Lionel LEGACY system. It will also operate on the original Lionel Trainmaster System (TMCC1) with limited features and also on the
LEGACY Cab-1L / Base-1L operating system (again with reduced features.) Using a Lionel LEGACY set
(6-14295) will allow you to access ALL the features this locomotive has to offer.
Your commands are sent by the Remote Controller to the Command Base, which broadcasts
a radio frequency that is distributed through the outside rails of the track to your locomotives.
Your locomotive will not respond until it recognizes its unique ID#, so you can operate multiple
Command-equipped locomotives on the same track at the same time.

Running your locomotive
Power your locomotive with an alternating-current (50-60Hz AC) transformer only.
Powering your locomotive with a direct-current (DC) transformer, or in excess of
19 volts AC, may result in damage to sensitive electronic components.
Your locomotive requires Lionel or Lionel-compatible O-36 or larger track curves.
TrainMaster Command Control (TMCC) operations
For operation in the TrainMaster Command Control environment, you need a TrainMaster Command Base (6-12911) and a CAB-1 Remote Controller (6-12868). Refer to your TMCC
System Manual for complete information. To access all the locomotive's features, you
must operate in the LEGACY environment, as discussed on the previous page.
Your commands are sent by the CAB-1 Remote Controller to the Command Base, which
translates the command and broadcasts a radio frequency that is distributed through the outside
rails to your locomotive, which will not respond until it recognizes its unique ID#. TrainMaster
Command Control gives you the power to operate multiple Command-equipped locomotives on the
same track at the same time.
1. Turn off track power, and then plug in the Command Base and connect it to the
track.
2. Place your locomotive on the track.
3. Increase track voltage to full power (no more than 19 volts AC). If a circuit
breaker trips when you turn on the Lionel power supply, check the wheels of your locomotive to
make sure they are all securely on the track. Check to make sure the track is free of all metals
that may cause a short circuit.
4. Press ENG and 1 (or the ENG ID# you set) to address your locomotive with
your CAB-1 Remote Controller.
5. Throttle up and move ‘em out.
For more information, please refer to the TrainMaster Command Control operations section of
this manual or the TMCC System Manual, available online at www.lionel.com.

Running your locomotive
Conventional transformer operations
For Conventional operation, a Command Base must not be powered up
anywhere in the area, even if it is not connected to the track. If a base is
detected, your locomotive will default to Command mode.
Power your locomotive with an alternating-current (50-60Hz AC) transformer only.
Powering your locomotive with a direct-current (DC) transformer, or in excess of 19 volts
AC, may result in damage to sensitive electronic components.
Your locomotive requires Lionel or Lionel-compatible O-36 or larger track curves.
1. With track power off, place your locomotive on the track.
2. Power up the track. If a circuit breaker trips when you turn on the Lionel power supply,
check the wheels of your locomotive to make sure they are all securely on the track. Check to
make sure the track is free of all metals that may cause a short circuit.
3. Move ‘em out! When the locomotive’s headlight illuminates and the LEGACY RailSounds
sound system starts, press the DIRECTION button on your transformer to sequence your
locomotive through the repeating pattern of operations: neutral, forward, neutral, reverse,
neutral, and so on. You may also briefly turn off track power to advance the locomotive to the
next operating state. Adjust the throttle until your locomotive moves at your desired speed.
When placing your locomotive on your layout for the first time and after power
interruptions lasting longer than five seconds, it will start out in neutral.
We recommend that you operate your LEGACY locomotive with Odyssey II
Speed Control turned on. You may choose to operate your locomotive without speed control
by placing the Odyssey II Speed Control System switch to the NO ODY position. See Figure 4 on page
8 for the location of the switch.
Use the HORN and BELL buttons on your transformer to activate those features. Adjust the
volume using the volume control knob. Refer to Figure 5 on page 9 for the location of this control.
For more information, please refer to the Conventional transformer operations section of this
manual.

Locomotive basics
Your locomotive is equipped with a smoke generator that produces safe, clean, white smoke dur- ing operation. A reservoir beneath the stack contains the fluid and a wick, which, once saturat-
ed, supplies the heating element with the right amount of fluid. Add 10-20 drops (shown in Figure
3) to prime the unit the first time you run the locomotive or after being stored for an extended peri-
od of time, and then add 10 to 20 drops to refill when smoke production decreases. When refilling,
DO NOT EXCEED 20 DROPS as this can cause your smoke units to become oversaturated allowing
leakage onto the electronics. Note that operating your locomotive's smoke unit without smoke fluid
will cause damage to the heating element.
If you prefer to operate your locomotive without smoke, locate the smoke unit switch and slide it
to the NO SMK position. Refer to Figure 4 on page 8 for the location of the switch.
For best performance, we recommend using 6-37841 Lionel Premium Smoke Fluid
only. Do NOT use smoke fluid from ready-to-run train sets.

The functions of your locomotive's switches are outlined below. Refer to Figure 4 for the location of the switches. The instructions below are specific to this particular locomo-
tive; note that available features (and switches) may differ from other loco-
motives and locomotive sets.
Smoke Unit Switch (SMK/NO SMK)
Used to turn the smoke unit function on and off.
Program-Run Switch (RUN/PGM)
Used to assign an ID# and to reprogram the locomotive for LEGACY and Command operation
when the switch is in the PGM position. Also used to “lock” your powered locomotive in a single
direction, or neutral, in conventional operation when the switch is placed in the PGM position.
Odyssey II Speed Control System Switch (ODY/NO ODY)
Used to turn the Odyssey II Speed Control System on and off.

Locomotive basics
Installing the battery
Although the LEGACY RailSounds sound system is powered through the track, you may choose to install a nine-volt alkaline battery if you find that the sound system shuts down during
track power interruptions (for example, at a switch or over a dirty section of track). Follow these
steps to install the battery.
If the RailSounds sound system turns off during interruptions in track power, you may
need to replace the battery. Use only alkaline batteries.
1. Remove the body screws from the underside of the locomotive. See figure 5.
2. Remove the protective cover from the battery harness.
3. Snap the battery harness onto the nine-volt alkaline battery’s terminals.
4. Slide the battery into the battery holder.
5. Replace the body and reinstall the body screws.
Be careful not to pinch any wires when replacing the body.

For operation in the LEGACY or TMCC environment, you will want to give each unit a unique ID#. The locomotive will respond to commands associated with its ID# while all other units will
disregard these commands. This procedure is not necessary for conventional (non-
Command) operation.
1. Slide the Command reverse unit switch on your locomotive to the PGM
position. See Figure 4 on page 8.
2. Place the locomotive on the track.
3. Connect the Command Base and plug it in.
4. Power up the track.
5. Press ENG on the CAB-1 or CAB-2 remote.
6. Enter the unique ID#. Choose any number from 1 to 98 that has not been
assigned to another locomotive (ENG). We recommend using a part of your
locomotive’s road number.
All LEGACY locomotives respond to ENG 99. We recommend that you reserve ID# 99 as a
"universal" ID#.
7. Press SET. The locomotive's horn will sound, or the headlights will flash if the
RailSounds sound system is off.
8. Slide the Command reverse unit switch back to the RUN position.
The locomotive’s ID# has been set. Be sure to record the new ID# for your reference.
