I have two of them -- Amtrak/DOT and Amtrak late. Both broke a gear on the truck (I suspect bad zinc). The wire gauge between the cars is a bit thin, so running two extra cars per prototype is hit or miss (the trailing unit sometimes loses communication) but overall I like the trains and how they've run. At some point I plan to go into the trailing units and set them up with free-standing proto-3 hardware to eliminate the tether issue on the full 5-unit trains. I think the trains could use a little re-engineering if they're re-issued (heavier tether wiring). The gear situation is the luck of the draw.
