Locking Your Locomotive Into A Single Direction - Lionel Big Boy Owner's Manual

Conventional transformer operations

Locking your locomotive into a single direction

W
hen the Command reverse unit switch (PROG/RUN) 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 a single direction (for example, to operate in forward
only), you can deactivate the Command reverse unit's sequencing function. Refer to Figure 2
for the location of the Command reverse unit switch.
1. Use your transformer's DIRECTION button or interruptions in track power to get your
locomotive moving in the desired direction.
2. Slow the locomotive down without stopping (reduce the throttle without turning off track
power).
3. Slide the Command reverse unit switch to the PROG position. At this point, the locomotive
is "locked" into your chosen direction. To restore the forward-neutral-reverse sequence,
just slide the Command reverse unit switch back to the RUN position.
