1937 AAR boxcars for Southern Pacific - Versions of B-50-20/21/ and 23 (specify O or P:48)

As the depression waned beginning in 1936, the SP began a steel boxcar acquision program using the new 1937 AAR 10’-0” IH design with a 3713 cubic foot capacity. This resulted in 7,994 new cars added to the eet by mid-1942, contracting with all major car manufactures.
 

This version is of the later design intoducing the new stronger round (W) corner 4/5 Dreadnaught ends and steel non-skid running boards.
