Please note that not all LEGACY products have all the features
mentioned in this section.
This section is a brief overview of the LEGACY Control System. For a more in
depth explanation of the LEGACY Control System features, please see your LEGACY
Control System Operations Manual or visit www.lionel.com to download a copy of
the latest LEGECY Control System maual.
GET READY TO RUN
Get your engine running now by following the instructions in this guide. We'll power up the track, "address the engine" so it can be controlled by your CAB-2 remote and learn to use the Velocity
Throttle, Whistle, Bell, Brake and Direction commands.
Power Up The Track
Refer to PowerMaster, TPC, or ZW manual for the correct method to power up. With your
locomotive on the track and ready to roll, power-up your track to a constant 18 volts. 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.
Address Your Engine
First, you must address the engine. This "tells" your CAB-2 which locomotive you want to control.
This is important when you have more than one engine on your layout.
To address an engine:
1. Press ENG
2. Press 1
3. Press Start Up
See reference numbers 1, 2, and 3
Start 'Er Up
Now it is time to start up your engine's sound system.
To start the engine's Railsounds system, press Start on the touch-screen or any action key
(Whistle, Bell, Velocity Throttle, etc.).
Your engine sound system will start up and the Touch-screen Control Panel will appear.

THE VELOCITY THROTTLE
The Velocity Throttle (that big red rotary knob in the middle of your Lionel remote) is used to start your engine moving, slow it down or speed it up. Use it simply by turning it
clockwise (speed up) or counter-clockwise (slow down).
4. Turn the Velocity Throttle clockwise a small amount. Your engine will begin to move.
5. Experiment with the engine’s response to the Velocity Throttle. Turn the Velocity Throttle
clock-wise and counter-clock-wise.
6. Slow and stop your engine by turning the Velocity Throttle counter-clockwise.
7
See reference numbers 4, 5, and 6

Boost & Brake
Boost and brake give you another way to control the speed of your train. Boost gives your loco a
temporary increase in tractive power, and returns to the previous speed when you release the control,
while the brake command slows you down quicker than the Velocity Throttle alone and holds your
speed at the adjusted level.
9. Experiment with Boost and Brake. Notice how your engine responds to the Multi-Controller.
See reference number 9
LEGACY Control System operations–overview
THE MULTI-CONTROLLER
Direction
The direction of your engine toggles between forward and reverse at the touch of the Multi-
Controller.
7. Press the Multi-Controller once. Your engine's lights will change directions.
8. Turn the Velocity Throttle clockwise a small amount. Your Engine will reverse directions
and travel in the opposite direction.

THE TRAIN BRAKE SLIDER
A
Train Brake is used to slow down and limit the top speed of your train by adding a load.
The more the Train Brake is applied by pulling the Train Brake Slider down, the more
laboring is heard from the engine. Eventually Train Brake application will slow down the train
and it is even possible to stop a train by pulling the Train Brake Slider all the way down. A
tremendous amount of laboring can be heard whenever you apply the Train Brake in a large
amount.
10. Experiment with the Train Brake. Try a small amount of the Train Brake when your
engine is moving down the rails at a medium speed. Notice the effect the Train Brake has
on sound and speed. Try adding more Train brake and notice that the Train Brake can
limit the top speed available to your engine.
Try adding even more Train Brake and notice that the Engine sounds like it is working
harder and harder as the Train Brake is applied more.

Experiment.
18. The speed of the engine
changes with each press and
release of a different RR
Speed key.
19. TowerCom dialog occurs each
time you press and hold a RR
speed key.
20. The Engineer dialog
responds and the speed of the
engine changes as soon as
you release the RR speed key.
21. If you touch a RR speed
key and release it quickly, a
speed change is enabled with
no dialog scene.
22. You can also use the Velocity
Throttle and other action
controls in this mode and
continue to use Official RR
speeds at the same time.
23. Repeat step 17.
24. Press AUX-1 to leave the RR speed mode and return to the standard mode and return to
the standard control panel.
25. Press the speed bar to toggle between the Official RR Speed Control Panel and the

GROUND LIGHT CONTROL
Your SD70M-2 locomotive is equipped with functional Ground Lights. There is one Ground Light located on each side of
the frame, near the center of the front truck. Prototypically, it is
difficult to determine when a diesel locomotive is moving at very
slow speeds in extreme low light, or darkness. When operating
the locomotive under these conditions, the Ground Lights provide
the engineer and fireman with a visual reference to the ground and allow them to more
accurately judge the motion of the locomotive.
AUTO MODE is the default operation of the Ground Lights. In AUTO MODE, the Ground
Lights are ON when the locomotive is stopped and they remain ON when the locomotive is
in motion through speed step 24. At speed step 25 and above, the Ground Lights are OFF.
When the locomotive slows to speed step 24, the Ground Lights will turn ON. In the Legacy
environment, you may activate the Ground Lights when the locomotive is in motion at speed
step 25 and above using the icon shown below to turn the Ground Lights ON. When the
locomotive comes to a stop by either throttling down or by pressing the DIRECTION button,
the Ground Lights will default to AUTO MODE. You may also set the Ground Lights so that
they will remain OFF when the locomotive is stopped or in motion by using the icon shown
below to turn the Ground Lights OFF. When the Ground lights are set to OFF, The AUTO
MODE is de-activated.
For optimal effect of the functional Ground Lights, operate your SD70M-2
locomotive in low light conditions.

TrainMaster Command Control operations
TrainMaster Command Control operations
In addition to your transformer, to operate your locomotive in the Command Control environment, you need a Command Base (available separately, 6-12911) and a CAB-1
Remote Controller (available separately, 6-12868).
Your commands are sent by the CAB-1 Remote Controller to the Command Base, which
then translates the command into digital code. That code is sent 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.
Keep in mind that track power is like gasoline in the tank of a car—it gives you the power
to go places, but it doesn’t tell you where to go or how fast to get there.

locomotive under these conditions, the Ground Lights provide the
engineer and fireman with a visual reference to the ground and allow them to more accurately
judge the motion of the locomotive.
The Ground Lights function automatically and are not user controlled. With the
Momentum set to “L”, the Ground Lights are ON when the locomotive is stopped and they
remain ON when the locomotive is in motion through speed step 4. At speed step 5 and above,
the Ground Lights are OFF. When the locomotive slows to speed step 4, the Ground Lights will
turn ON.
With the Momentum set to “M” or “H”, the Ground Lights are ON when the locomotive
is stopped and they remain ON when the locomotive is in motion through speed step 12. At
speed step 13 and above, the Ground Lights are OFF. When the locomotive slows to speed step
12, the Ground Lights will turn ON.
For optimal effect of the functional Ground Lights, operate your SD70M-2
locomotive in low light conditions.

TrainMaster Command Control operations
Tuning your locomotive’s performance
TrainMaster Command Control allows you to fine-tune the performance of your locomotive. Use your CAB-1 Remote Controller to make these adjustments. See page 17.
These settings will be lost if you assign a new ID#.
RPM RUN LEVEL
Your locomotive has eight levels of RPM sounds, corresponding to the eight run levels in
a real diesel locomotive. The three ways in which you can control your locomotive's RPM
sounds are discussed below.
Automatic RPM Mode
In Automatic RPM Mode, your locomotive's RPM run level is controlled by movements of
the throttle on your CAB-1 Remote Controller. A small clockwise motion of the throttle knob
will cause the RPM sounds to ramp up one run level, while a small counter-clockwise motion
of the throttle knob will cause the RPM sounds to ramp down one run level.
While the locomotive is ramping between run levels, it will ignore additional throttle
movements. Once the RPMs have finished ramping to the next run level, additional throttle
motions will again trigger another RPM ramp. This feature will allow you to "fine-tune" your
RPM run level, regardless of the locomotive's speed, using only the throttle knob. This mode is
the default setting for your locomotive on power up.
Manual RPM Mode
In Manual RPM Mode, you can set your locomotive's RPM run level to a constant value by
pressing the AUX1, 3or AUX1, 6key sequences on your CAB-1 Remote Controller. When your
locomotive is in this mode, its RPM run level will not vary with throttle movements or with the
speed of the locomotive.
To enter Manual RPM Mode, press the AUX1, 3key sequence while the locomotive is
stopped, or press either the AUX1, 3or AUX1, 6key sequence while the locomotive is
moving. Pressing AUX1, 3will cause your locomotive to enter Manual RPM Mode and ramp
up one RPM run level; pressing AUX1, 6will cause your locomotive to enter Manual RPM
Mode and ramp down one RPM run level. You may then press the 3or 6key additional times
to ramp your locomotive's RPMs through all the run levels. Once you set your locomotive's
RPM run level it will remain there until you change it with the 3or 6keys, or until you exit
Manual RPM Mode.
You may cause your locomotive to exit Manual RPM Mode in several ways: reset the
locomotive with AUX1, 0key sequence; enter the shutdown sequence with the AUX1, 5key
sequence; or turn off the track power and allow the locomotive to reset.
Speed RPM Mode
In Speed RPM Mode, your locomotive's RPM run level is controlled only by the actual
speed of the locomotive.
Note!

20
TrainMaster Command Control operations
Tuning your locomotive’s performance (continued)
Speed RPM Mode (continued)
To enter Speed RPM Mode, press the AUX1, BRAKE key sequence while the locomotive
is stopped. A distinctive "clunk" sound will be heard. Once your locomotive is in Speed RPM
Mode, the RPMs will ramp up and down through its eight run levels depending on how fast
the locomotive is moving on the track. (Note that this is how your locomotive's RPMs are
controlled when it is running in Conventional Mode.)
To exit Speed RPM mode, reset the locomotive with AUX1, 0key sequence or turn off the
track power and allow the locomotive to reset.
ADJUSTING THE SPEED
The BRAKEandBOOST buttons give you incremental control of your locomotive’s speed
while you press and hold these buttons, allowing you to make small, gradual adjustments
around curves and over grades. The locomotive will resume its initial speed when the buttons
are released. Listen for the squeal of your locomotive’s brakes when you use the BRAKE
button.
SOUND LEVEL
Press AUX1,1or 4on your CAB-1 Remote Controller to raise and lower the volume of the
background locomotive sounds, such as RPMs and air release or let-offs. The horn, bell and
dialog will be unaffected. Note that this setting is preserved through power down and system
reset. Remember that the sounds will be silent when you power up your locomotive if the
sounds were turned down previously. To set the maximum volume of both the background and
foreground sounds, we recommend that you adjust your locomotive’s volume control knob
(see Figure 3 on page 30 for the location).
