Not sure this is the correct forum but here is my current problem.
VL Bigboy runs great , remove the BB and put the VL Hudson runs great.
Next day
VL Bigboy placed on the track, power the track and the engine starts smoking and making noise. Headlight is NOT flickering. I know this is not right so the track power is turned off and VL BB is taken off the track.
Place the VL Hudson on the same track , power up, no noise or smoke until the engine # is identified on the cab 2, engine runs great.
I have tried switching engines 3 times and get the same result.
All comments appreciated.
