That rib side Tyco hopper is based on the Pullman Standard 4,740 cubic foot capacity
car, not the PS-2.
Jeff, *any* Pullman-Standard covered hopper is a "PS-2".
But speaking of the Accurail car, yes, it is based on the slightly higher capacity 4750 cuft. design, which is also offered by Intermountain and Tangent in full mind-blowing level of detail.
