I believe Circuitron sells a device that does this, all you need to do it hook it up, the circuit is already built. There's another company that is at all the train shows around here who also sells one, usually has a demo set up at their table with it running. The name COMPLETELY escapes me at the moment - Berkshire Junction or something like that?
