Our museum's auto-reversing unit for a trolley exhibit has failed. The unit is a Peerless Ind., 525-HO. A search shows it's no longer made, and none are available from suppliers I know of. Are there other auto-reversing units available? Thanks. Edit: The exhibit is N-Scale DC.
Bachmann has an HO Trolley “starter set” that has a reversing unit. I think there’s is an n scale version too. There are probably others, but that is the first that comes to mind. My modular club has a module with a auto reversing trolley. The unit underneath is some kind of PC board, but I don’t know much about it.
Please check out CIRCUITRON COMPANY/ http://www.circuitron.com/ I know they have one listed in their catalog.
