The rail line was substantially upgraded between 2002 and 2005 and features continuous welded rail across its entire main line. The line handles railcars and has vertical clearances sufficient for double-stack intermodal cars throughout.

The filming was done at Fort Chaffee, Van Buren, and on the Arkansas & Missouri Railroad. The car, built for the Delaware, Lackawanna & Western’s steam powered suburban service out of Hoboken, New Jersey, reportedly carried commuters in New Jersey until 1982. The car was built by Pullman in 1917 as an early steel car using many of the design standards used with earlier wooden cars. It has open end platforms (one of the last large orders of open-platform coaches ever built), windows that open, and clerestory roofs.
