Hello all,

Having an issue with a Bachmann Consolidation 2-8-0 HO scale locomotive. I purchased this in a lot off eBay and it arrived today. Upon putting it on the track, the engine moved a few inches then quit. I have only a dim headlight and a "humming" noise which sounds like the gears trying to work. I tried it on multiple tracks only to have the same thing happen. I did a little disassembly and noticed I cannot move the gears to the wheels whatsoever. This is not new engine, at least a couple decades old, however, it is in new condition and looks to never have been run (plastic still on in original box). I love the locomotive and really don't want to have to send it back to the seller- does anyone have any ideas as to why I have this problem and if I can fix it?

Thanks!
