Reverse unit procedure
T
he reverse unit inside your Lionel
NW2 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 inter-
ruption. Power inter-
ruptions are the sig-
nal that tells the
reverse
unit
sequence to the next
operational state.
To interrupt power
and sequence the
locomotive's reverse
unit, press the direc-
tion control button, or
turn the throttle to the O

again. The reverse unit alternates
N
between three states: forward, neutral,
and reverse.
Also, the locomotive can be "locked"
into a certain mode of operation by
throwing the switch located on the
underside of the frame (see illustration
above). When the switch is thrown to the

position, the locomotive will be

and the switch is thrown back, the loco-

reverse unit has a
"power-up reset"
feature, which means that should the
locomotive sit without power for a
short period of time, the reverse unit
will automatically reset and start in the
forward direction when the transformer
is turned on or "powered up," regard-
less of the locking switch position. If the
locking switch is in the O
locomotive will start in the forward
direction and be "locked" there.
