including covered hoppers, phosphate cars, and hopper cars.
Modernization continued during World War II, when Seaboard
received 500 1937 AAR-design all-steel box cars in three lots from
Pullman Car &Manufacturing Co. in Bessemer AL.
The B-8 cars
The 1937 American Association of Railroads (AAR) box car
was an evolutionary improvement over the American Railroad
Association (ARA) 1932 car. The 1937 design featured improved
height (generally 10’ 0” inches interior height), ten-panel riv-
eted sides (five panels on each side of the door, stamped 4-5
two-panel dreadnaught ends, AB-schedule brakes, 6’ door
opening, and a Murphy roof.
The cars were built by many of the major builders, such as
Pullman Standard, Mt. Vernon, American Car & Foundry,
and many others, and many railroads built the cars at their
own shops. Many variations were constructed with differ-
ent roofs, trucks, doors, brake wheels, and other hardware to
suit the individual railroad companies. An excellent primer by
Ed Hawkins on the 1937 AAR box car appeared in RailModel
Journal, July 1991, Vol. 3, No. 2. That magazine is available for

The first of Seaboard’s AAR 1937-design cars were delivered in
September 1944 from Pullman Lot 5768, numbered SAL 19500-
19699. The cars were about as standard as they came from
Pullman at that time, with 4-5 dreadnaught ends, Murphy roof,
W-section corners, Youngstown corrugated doors, AB-schedule
brakes, Apex running board and brake step, and an Ajax brake
wheel. Trucks were of the AAR standard type with one-wrought
33-inch diameter wheels.
The cars were painted DuPont SAL Standard Color (freight car
brown) with white stencils, “The Route of Courteous Service”
slogan, and the 56” monogram featuring the word “Railway”
