Not so fast, my friend. When discussing hoppers, do not go by appearance alone. You have to take dimensions into account, notably IL and height of top chord above rail as they contribute to the overall appearance of a cut of hoppers. For example, as David Thompson pointed out, the NYC System cars are dimensionally similar to the USRA twin, with IL of 30 ft 6 in/height of top chord above rail 10 ft 11 in (actually taller than the USRA twin), while the IC cars had an IL of 33 ft/height of top chord above rail 10 ft 8 in. To put the difference in length into context, put a Tichy or Accurail USRA twin hopper next to an Athearn twin hopper.

If you drill down into the other cars, you'd find more differences; for example, the DL&W cars had an IL of 34 ft, and you mixed in 40 ft cars, which further muddies your analysis.
