Locking your SD40 into a single operational state
T

your Lionel SD40 (example: forward
only), you can deactivate the LCRU2's
sequencing function with the reverse unit
control switch, located on the underside of
the locomotive.

Using your SD40' s Electrocoupler
Y
our SD40 front and rear Electrocoupler™
will respond to the coupler release but-
tons on your CAB-1 remote when operated
in the TrainMaster Command environment
(see page 9 for button location). During con-
ventional operation, the Electrocouplers will
react to the magnetic field generated by a
Lionel remote-control track section (avail-
able separately).
In TrainMaster Command operation, sim-
ply press the c
F (front) or r (rear) but-
oupler
ton on your CAB-1 remote, and the coupler
opens, accompanied by the Railsounds cou-
pler release sound.
In the conventional mode, place the cou-
pler's "trigger disc" over the remote-control

out stopping. Set the reverse unit control
switch to PROGRAM/LOCK. The SD40 is
now "locked" into your chosen direction.
When you no longer want single-direc-
tion operation, just slide the reverse unit
control switch back to FORWARD/ RUN.

One operating technique favored by
Lionel railroaders is the "moving uncouple. "
Press the c

open and the consist will remain behind as

But be careful when uncoupling—the
speed of a newly uncoupled and moving
locomotive can increase dramatically.
