Basic Operation; Activating Features - Lionel 249 Steam Freight/ Passenger Set Operation Manual

Basic Operation

The Throttle knob controls how fast your train will travel.
The locomotive is stopped, started and reversed by means of the reversing 'E-Unit'
located inside the locomotive. The E-Unit is a three position sequence relay which
cycles whenever current to the locomotive is interrupted. This can be done by
operating the 'direction' control on the transformer, or by moving the transformer
voltage control to the OFF position. The sequence of its operation is Forward,
Neutral, Reverse, Neutral, etc. In other words, if the locomotive is in forward
motion, operate the 'Direction' control once to stop it, and twice to reverse it.
If you want to operate the train in one direction only, which is necessary if you
have automatic stations or Insulated blocks in your layout, you must 'lock-out' the
E-Unit. Make sure the locomotive is moving in the desired direction then stop it.
Now, move the E-Unit lever (located at the rear of the motor) to its OFF position
or toward the right side of the locomotive. If the E-Unit is 'locked out' while it is
in the Neutral position, the locomotive will not run at all. Also, because the E-Unit
works partially by gravity, it will not operate properly if the locomotive is held on
its side or upside down. To resume normal operation move the E unit level to the
left.

Activating Features

Throttle- To increase or decrease track voltage, and therefore train speed, turn the
throttle control knob. Turning clockwise will increase voltage and speed, while
turning counterclockwise will decrease voltage and speed. The engine will maintain
the speed you set after you release the throttle until you turn it again to change the
voltage and speed.
