I have "collected" what I believe to be an entire set of the Bachmann Emmit Kelly Circus trains.   At a show earlier this month the 4-6-0 was run for 8 hours a day for three days and the motor fried.   I sent it back to Bachmann for repair no problem.   The unit came home today and I don't know if I have a problem or not.    I sent it in with red wheels but it came back with black wheels.   

I would like to know if other collectors think that the "collector value" on this unit just become zero since it is not as it was from the factory?
