I dug through my photo archives for some pictures taken on my old layout.
Railbox:
ACF Centerflow hopper (ex Pacific Rail Shops)
40' Ice Reefer (ex Pacific Rail Shops)
FMC Double door modern boxcar:
Evans double plug door boxcar:
Tank car (ex very early original S Scale America. When Ron Sebastian bought the line, he also bought the SSA name)
Pretty much all of the cars come equipped with HiRail Wheels and Flyer-compatible couplers. Many of the cars have scale wheels included but no scale couplers. The latest cars like their modern Thrall gondolas come as HiRail only. I'm given to understand that Des Plaines will swap out the wheels at no charge, but don't hold me to that.
The former Pacific Rail Shops cars have a little more fragile detail than the cars designed by SSA/DPH, but all are quality cars with superb graphics.
Des Plains Hobbies is the go-to place for S Scale America because they own the tooling. However, since the passing of Ron Sebastian, the future for SSA cars is cloudy.
