3Move ‘em out!
Get your locomotive moving. Press the DIRECTION button on your
transformer. This sequences the reverse unit to the next operating state.
Adjust track voltage until your locomotive moves at your desired speed. To
increase speed, increase track voltage. To decrease speed, reduce voltage. To stop the
locomotive, turn-off track power.
See page 4 for information on locking your locomotive into a single
operational state.
Place your locomotive on American Flyer or S gauge
two-rail track.
The curves must have a radius of at least 20”.

2Power up your locomotive with your transformer.
Your locomotive is designed to operate on 9-15 volts alternating
current. Virtually all American Flyer or Lionel alternating-current transformers
are suitable.
Do not power your locomotive with direct current (DC).
Damage to sensitive electronic components may occur.

Running your locomotive with a Lionel transformer
Transformer operations
Caution!
Note!

To select a single operational state for your locomotive (example: forward
only), you can deactivate the reverse unit’s
sequencing function with the directional
control switch.
Get your locomotive moving in the
desired direction, then slow it down without
stopping. Set the directional control switch
to OFF. Refer to Figure 1 for the location of
the switch. The locomotive is now “locked”
into your chosen direction.
When you no longer want single-direction
operation, just slide the switch back to ON.
Your locomotive’s reverse unit will
“reset” to forward after any five
second or longer power
interruption, regardless of the
original locked-out direction.

Transformer operations
Push up on the uncoupling weight located directly under the coupler to
open the coupler. To couple two cars
together, place them on the track with at
least one of the couplers open, then slide
them together. The couplers will close
automatically.
