The AAR approved a new standard box car design in 1937, which was more or less an improved version of the earlier 1932 box car design. The AAR 1932 box car received some interest by railroads, but the 1937 AAR design was the first standard steel box car built in large quantities. Thousands were built between 1937 and 1944 with many remaining in service until the 1980's. This modified version of the 1937 design includes an increased interior height of 10 feet 6 inches.
