I have the Lionel 6-37996. I am sure it has not much more or less than 2 hours of operation. It acquired a grinding and groaning sound and finally quit working. The motor sounds like it is humming, (or something is humming), so I need to get it fixed. Has anyone had the same problem? What is the probable repair? Since I bought it over a year ago before being put into operation it is not in Warranty. Thanks for your suggestions, as I would like to repair myself if possible.
