Should have posted this earlier. Within 2 days of contacting Bachmann support, Laura e-mailed me that she would send me a couple of sets of trucks. She did; I had them in a day or two; problem solved! Good customer service by Bachman! Thanks to them!

One wheelset on one truck on this car has no insulator at all. On other cars that work, each wheelset has an insulator and insulators are both on the same side, alternating sides on each truck. I think I'm missing an insulator. Haven't gotten the meter yet but contacted Bachmann service and they also told me to check the insulators. I didn't know then that one was missing. Will get back to Bachmann service and arrange to send back or have them send me a new truck or two. Thanks for the help. Obviously members here know their stuff!

Thanks for the info, I'll try it. Going to give Bachmann service a call tomorrow too since the set is brand new.

Just bought an N scale Royal Blue set from Model Train Stuff and it runs fine except when one of the two passenger cars is on the track. Track is fine. Locos (also others) run good, but with any train, any loco, any other cars, putting this one passenger car anywhere on the track stops the train! It seems to be 'closing the circuit'.(?) Any ideas?
By the way, I'm new here so I'll say hello. I'm Jeff from PA. Had N scale since 1977 but it sat in a box from 1987 until before this past holiday. I've learned what little I know the hard way, setting up and figuring out what doesn't work. Thanks for any help with this latest problem.
