How do they compare to premier MTH?
The MTH stock car is a larger, post WW II car with dimensions similar to an AAR box car. Unlike the similarly dimensioned Trainman and Weaver stock car models, the MTH stock car does not share roof and end tooling with another model. The MTH stock car has a Stanray diagonal panel roof, unlike any MTH 40 foot premier box car. It is an interesting model.
While a stock car with wood ends would be a nice addition to the O scale options I would like to see a stock car with Murphy ends. Many USRA type box cars were rebuilt into stock cars and sported 5/5/5 or 7/8 Murphy ends. Hopefully MTH or Atlas has USRA box car tooling that can accept different sides and make a new stock car an inexpensive product to develop.
