I got a replacement 2-8-0 from bachmann it ran about 10 feet and then stopped noticed it was out of QuarterSo I phoned bachmann they happily sent me a replacement New one arrived same problem I think I will fix this one myself Anyone else have this problem It seems the wheels are loose on the gear shaft causeing them to turn independent of each other in other words the right can slip without the left moveing I put them back in Quarter a used lock tight works fine now Ken
