Southern Pacific B-50-8 through B-50-14 Series USRA clone boxcars
SP had a large fleet of cars based loosely on the USRA design from WW1, while SP did have a small number of proper USRA cars in their B-50-12 class, these were all rebuilt into all steel cars in 1949 and 1950.
Folsom Locomotive Works is proud to bring you: the rest of SP’s iconic USRA copies.
SP used Z-bar instead of the normal stamped metal ribs for their single sheathed cars, along with several class specific designs.
below is a simplified roster of SP’s single sheathed USRA boxcars:
