People on this thread are right to call attention to this defective design.
I first encountered major problems with this design with my CSX 66’ mill gondolas (first run). My biggest issue both cars would derail constantly on curves due to the lack of swing in the coupler. They would no even run on O72. The truck design is unusable, I needed to waste money on on already expensive car and install trucks from the older design.
I have not purchased any Lionel freight using this design in the last 5 years, and until they scrap this faulty design, I will be sticking to Atlas and what’s left of MTH
Are you talking about gons like these?
I was looking at picking some up but if they can't even handle O72 then I am not interested.
