QUOTE: Originally posted by Railroading_Brit This isn't normal for the N-scale U36B - I have one that ran superbly straight from the box and is still great - no flywheels, but low gearing so it runs well without them. Try cleaning out and regreasing the trucks, and add a drop of oil to each motor bearing. Alternatively, you could take it back to the store and ask their advice - explain you're not happy with it and they may offer to either replace it (if so, get them to test run the new one!) or they may be able to give you some pointers as to how to sort it out. Hope this is of some help!

QUOTE: Originally posted by cacole A better track cleaner than rubbing alcohol, in my opinion, is Nevr-Dull Magic Wadding Polish, which can be purchased at most Wal-mart, K-mart, Pep Boys, or other stores that sell automotive accessories. Nevr-Dull is cotton soaked in some type of metal polish. I use it because you do not have to go back with a second wiping to take off the dried polish like you do with Flitz or other polishes that come in a tube.
