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.
Bell: To sound the bell, in an engine equipped with a bell firmly press and
release the 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.
