Welcome to the forum DCFD!
Even though these cars are not scale I am somewhat interested in them because I have ridden on both the Reading Blue Mountain and Northern, and the Lehigh Gorge Scenic Railway and I have a RBM&N locomotive on pre-order. I was looking at on line photos of the prototype and I noticed almost all of the pictures I saw show the prototype with 4 wheel trucks. Some of the LGSR cars have some strange looking trucks that I have never seen before. I doubt that models of those trucks are available in O scale but I could be wrong. I wonder if in the deal Atlas made with MTH if they have access to all MTH trucks (sorry—if that was mentioned I missed it) and if Atlas will consider using 4 wheel trucks where appropriate? Just talking here and not knocking the cars. I am happy they will get made for the folks who want them. I am just on the fence about them.
