Basic Operation

The Throttle knob controls how fast your train will travel.
Turn the throttle knob up ½-way, until the engine and caboose lights shine bright.
Put the engine into motion by pressing the Direction button on your transformer once.
(hold it for approximately 1 second)
If the engine does not begin to move as soon as you firmly
press the Direction button, you may not have sent enough
voltage to the track to make the train move. Turn the throttle
up a bit higher until the train begins to move.

Operation Buttons

Throttle To increase or decrease track voltage, and
therefore train speed, turn the throttle control knob.
Turning it clockwise will increase voltage and speed, while turning it 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.
Horn/Whistle - To sound the whistle, firmly press the Horn/Whistle button. The horn
will sound for as long as you continue to depress the button. It will stop when you release
the button.
Bell - To sound the bell, firmly press the bell button. The bell sound will continue until the
bell button is firmly pressed a second time.
Direction Your train is programmed to start in neutral. The train
will always cycle neutral-forward-neutral-reverse with each press
and release of the direction button. The engine is programmed to
restart in neutral each time the track voltage is turned off for 25
seconds or more.
Volume Control – To adjust the volume of all sounds made by this engine, turn
the master volume control knob located under the fan cover clockwise to increase
the volume and counter-clockwise to decrease the volume (see Fig. 4 ). See Page 6
to show how to remove fan cover.
