Hi,  Question if train could be sent in for service.  I have item #0651, Consolidation 2-8-0 w/smoke purchased 12/27/1979 was running and now just revs.  Have the original receipt from Two Guys, warranty card must of been sent in back in 1979 because I have the top half, and I have the original paperwork that came with the engine to service it, and it's in the original box.  Can it be sent in for service and receive the same engine back?  I don't really want to be messing with a 35 year old train.  I've had this since I was 12.
