With 45-50% of the former SHS line still to be re-released, it will be quite some time before any true newly tooled freight car or locomotive appears.
Still to be re-released: Standard flat car, bulkhead flat car, single sheath outside braced boxcar, double sheath boxcar, stock car, ribbed side hopper, offset side hopper, panel side hopper, war emergency hopper, covered two bay ribbed sided hopper, 3-bay PS2 covered hopper, SW1, SW7/1500, 2-8-0 (I think that's all.)
