Running your Lionel SD40 with a Lionel transformer
Place your SD40 on Lionel or Lionel-

compatible
• Note the pull of Magne-Traction between your SD40 and the steel track.
Magnetized wheels and axles increase your pulling power (more than
25 cars on straight and level track) and keep your SD40 on track while
passing swiftly through curves.

Power up your SD40 with your transformer.
• Your SD40 is designed to operate on 7-18 volts alternating current.
Virtually all Lionel and Lionel-compatible alternating-current trans-
formers are suitable; we recommend the TrainMaster Command model
railroad control system.
• D
o not power your
electronic components may occur.
• When you first power up your track, the SD40 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 SD40's headlights will illu-
minate and Railsounds will fire up. At this point, the SD40 is in neutral.
(This occurs when placing the SD40 on your railroad for the first time.
Thereafter, it starts in forward after every three-second power inter-
rupt.)

Move 'em out!
• Get your SD40 moving. Press the DIR button on your CAB-1 remote or
Lionel transformer. This sequences the Liontech Command reverse unit
(LCRU) to the next operating state. The LCRU alternates between three
states: forward, neutral, and reverse.
• Adjust track voltage until your SD40 moves at your desired speed. To
increase speed, increase track voltage. To decrease speed, reduce volt-
age. To stop the locomotive, cut track power.
• To select a single operating state (example: forward only), you can deac-
tivate the LCRU's sequencing function. Get your SD40 moving in the
desired direction, then slide the reverse unit control switch on the
SD40's underside to PROGRAM/LOCK. See page 4 for the switch loca-
tion and positioning.
