lettering set for B-50-24 Overnight Scheme - beginning in 1946

The rst boxcars to arrive on the SP at the end of govenment materials controls at war’s end, were 500 Class B-50-24, 50-ton boxcars from

an order from Mt. Vernon Car Company between July and September, 1946. The rst 450 were painted black for Overnight LCL service and

the remaining 50 painted in dark green passenger color to operate as head-end baggage-express cars in passenger service. Original Series

numbers were 97620-98069*, and for the passenger service, Series 5700-5749.*
 

The most noticable features were a new improved 3 over 4 dreadnaught end, and thinner side sheeting requiring an alternate center rivet

design, although not evenly spaced like the UP and SSW, and improved light weight Youngstown 6‘ doors. (In 1955, the cars were repainted

into an all-aluminum paint scheme - see Protocraft Decals SP Overnight-3.)
 

* In 1956, all cars were renumbered into Series 121834-122311, and 133000-133018 respectivly.
