Throttle
- To increase or decrease track voltage, and therefore train speed, turn the
throttle control knob. Turning clockwise will increase voltage and speed, while

the speed you set after you release the throttle until you turn it again to change the
voltage and speed.

Bell button. To turn the bell off, press and release the Bell button again. The bell will
continue to ring from the time you turn it on until you press and release the button
again to turn it off.
Horn/Whistle
- To sound the whistle, firmly press the Horn/Whistle button. The
whistle will sound for as long as you continue to depress the button. It will stop
when you release the button.
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.
