Boxcar, 50 Foot, Steel

History: While the 40-foot boxcar was a standard design, and it did come in different setups depending on the type of freight being transported, it was not large enough for efficient mass commodity transportation. The 50-foot boxcar made its first appearance in the 1930s and steadily grew in popularity over the years, which further improved redundancies by allowing for even more space within a given car. Today, the 50-footer remains the common boxcar size. After the second world war ended, and steel became once again readily available, steel became the go-to choice for construction of boxcars. Pullman Standard and ACF were some of the most prolific builders of these cars.

These cars came in many variations. For instance, double-doors became practical for large/wide loads, end-doors useful for very large lading such as automobiles, and interior tie-down equipment was helpful in keeping sensitive products from being damaged in-transit. In 1954 the Santa Fe developed its "Shock Control" (and later "Super Shock Control") technology for new boxcars with upgraded suspension systems to further improve the ride-quality and reduce the chance of damaging freight.

In the 1960s, the flush, "plug" style sliding door was introduced as an option that provides a larger door to ease loading and unloading of certain commodities. The tight-fitting doors are better insulated and allow a car's interior to be maintained at a more even temperature.
