Can I add this to my HO Scale Norman Rockwell Christmas train? How does it connect between the other cars?

This item does not connect to a train. It runs on its own.

will this product work on a Bacman reversible system?

Theoretically, yes. However, it is so light with so few electrical pick-ups, that it may not work reliably in terms of triggering the reversing circuit.
