Reply to "MPC Era Diesel Horns"

TOMCO,

The horn and bell are activated by a DC voltage added to the track by the Activation Buttons. The horn blows with one polarity, and the bell rings with the opposite polarity. Depending how you wire the button, you can get either polarity. You need two Buttons to get both polarities available.
