How come Bachmann sells their trucks with no wheels? What wheels will be compatable with these trucks?
IIRC Bachmann uses a 0.563 axle length.
Been a long time since I fooled with Bachmann trucks, I have standardized on MT trucks and couplers, they use a 0.540 axle length.
Both Atlas and FVM metal wheels are on most of my stock.
33" for freight and 36" for passenger.
There are exceptions.
Good luck
