If this is the case the possibility is that the wheels have been taken out and replaced in reverse position during a cleaning operation.

You might have the same problem. I replaced it with a larger piece of plasticard.

Both bogies must be wired positive to positive and negative to negative as if not they are creating their own short circuit.
You will also need to check that the wiring is sympathetic to the other loco’s on your layout, IE that when you turn the controller on to go forward all locos go the same way, to do this disconnect one bogie and test the direction is the same as the other loco’s then reconnect the other bogie to the same polarity, if loco is not going in the right direction then reverse the wiring from both bogies to the motor.
If this loco has a drive shaft and the bogies are driven by bands from the drive shaft to the bogies then one bogie will need its drive bands reversed
Trusting this may be of help to you kindest regard John
