Just started fiddling with my N scale stuff after having it just 'sit' for about 15-20 years (it was all boxed up and dust free). No problemwith the diesel set I had purchased in the 80's, but could not get the bachmann steamer to work reliably. Fiddled and finally got it running well in reverse - then two of the wheels came off the engine. I have original box and warranty card - anyone venture a guess as to my chances that they'll live up to their limited lifetime warranty? I have filed a report via their service desk - happy to let you know how it works out if anyone is interested.
