I recently got a second hand Rail Truck that I have restored, including new gears and motor, and verified the motor worked before installing and that the gears moved freely. The problem is that the lights respond to the DCC lights on/off switch but the motor does not. I have reprogrammed the DCC decoder several times but I cannot get any response from the motor. (not even a hum as though it were trying to run). Does anyone have any idea what I can do to narrow down the problem? Would the light work if the chip were bad? Any ideas would be greatly appreciated.
Get yourself a decoder tester and see if the decoder is working.
Other than that, double check all your connections.

You can also try wiring up a 'dummy plug' that sends rail voltage directly to the motor, as if it were a DC model.
Then touch a 9v battery directly to the rails and see if the motor turns.
