less than 10 railroads had URSA type Pacific's. Why not just make those and move on?
Actually, more USRA loco were built after the first allocations, as "copies" and later "based ons". This varied with type, but the USRA Light Pacific was a widespread basis. Also, the USRA-ness of a loco was not so much the surface appearance as it was the specs and dimensions
The beautiful USRA 2-6-6-2, popular with us modelers, was never copied, and only 30 were ever built.
Unfortunately, MTH in particular insists on calling its USRA 4-6-2 a "USRA Heavy Pacific", but it is actually more the Light Pacific above than the Heavy.
The old Samhongsa Williams brass USRA Pacific was pretty much a Heavy. Bigger boiler, different, lower domes. A huskier look.
