RW F37

Twenty F37 well pocket flats were built at Altoona in 1942. They had a capacity of 70-tons, were 39'0" long over strikers, and had a pocket well measuring 18'5-1/2" by 6'4-5/8". The cars were constructed of riveted steel plates with a steel plate deck. Five triangular supports on each side added strength. The brake line ran outside of one side of the car. The cars initially ran on 2E-F19 Barrett-Whitehead trucks, though some were later fitted with 2E-F2 Crown trucks.

The F37B were true well hole flats and featured a heavy supporting frame and no floor. Loads had to be fitted into custom wood or steel framing. They were constructed from former FN cars between 1948 and 1952. Length over strikers was 38'4"; the well measured 16'8-3/4" by 7'0". They ran on 2E-F2 Crown trucks.
