B-Man and Todd, you're both right, its a P2K.  Sorry about that!  Todd, glad to hear mine isn't the only problem out there.  Will check the gear casing under the trucks.  The engine stops on track after passing over the Atlas turnouts tho.  Anyway of raising the body up off of the trucks without taking the whole thing apart?  How do you grind it down?  Dremel?

Thanks.  Mark

I have a Bachmann SW900 that is stopping mid-travel when it runs into something on the track.  This happens most often at turnouts.  It runs around most of my layout but then stops abruptely, as if a track nail were sticking up.  I have checked the track of course but find nothing that is protruding high enough to stop the locomotive.  No cars or other engines encounter this problem.  Is there a low-clearance on the SW900?  Is there a way I can raise the body/lower the trucks so that this doesn't happen?  This is a nice little engine, but it can't.

Thanks,
Mark
