Automatic Reverser

[Signalman]

G'Day all.  Does anyone know where I can obtain a circuit diagram or a complete track power reverser. I want to use it to operate a trolly car on a 3 mtr length of track through my "town". So it goes back and forwards on the length of track. Many Thanks.  Col.

Try looking here. He has a lot of circuits you can build.

The On30 Trolley set would be a "silver spoon" source.
