Reply to "Reading Passenger cars?"

I will second what Tom says. I have never had any tracking problems with the AM heavyweights on Gilbert track or on my semi scale layout with the SHS/MTH track and custom laid turnouts. I did have a few problems with three out of the eighteen cars derailing when backing through some of the #6 turnouts into the passenger yard. The cause was low hanging couplers. Since I replaced all the 4 wheel trucks with the AM 6 wheel trucks all these issues were resolved and the cars look better as well. The AM cars now operate without any issues.
