I'm trying to get an old H0 scale Bachmann Brill Trolley (Hershey paint job) working again. It had the pancake motor that wasn't working correctly, and still doesn't even after I took it apart and threatened it.

Where can I find a replacement either of the motor or, perhaps better, a new powered truck that will fit?  Has anyone modified something like this to work with the powered truck available from Bachmann?

Thanks for any help you can give!
