Locking Your Locomotive Into A Single Operational State - Lionel Hudson Owner's Manual

Transformer operations

Locking your locomotive into a single operational state

T he reverse unit inside your Lionel loco-
motive is an electronic device that acts
like the transmission in your car. When you
apply power to the track, the locomotive
moves in the direction specified by the
reverse unit—or it sits in neutral, awaiting
another power interruption. Power interrup-
tions are the signal that tells the reverse unit
to sequence to the next operational state.
To interrupt power and sequence the loco-
motive's reverse unit, press the direction con-
trol button or turn the throttle to the OFF
position and then ON again. The reverse unit
alternates between these states: forward, neu-
tral, reverse, and neutral.
Also, the locomotive can be "locked" into a
particular mode of operation by throwing the
reverse unit switch located on the underside
of the frame (see Figure 2). When the switch
is thrown to the OFF position, the locomotive
will be locked in the next mode of operation
Figure 2. Switch locations
in the sequence. For instance, if the locomo-
tive is moving forward, then is stopped and
the switch is thrown back, the locomotive
will be "locked" in neutral. If the switch is
thrown to the OFF position while the locomo-
tive is under power, the locomotive will
remain in the mode it was in when the
switch was thrown. The controller direction
button will then have no affect on the direc-
tion of the locomotive.
Should the locomotive sit without power
for a short period of time, the reverse unit
will automatically reset and start in the for-
ward direction when the transformer is
turned on, regardless of the reverse unit
switch position. If the switch is in the OFF
position, the locomotive will start in the for-
ward direction and be "locked" there.
