Mit Volldampf nach Chicago

The film used Union Pacific tracks in Arkansas, which were formerly the tracks of the Missouri Pacific Railroad. Mary Steenburgen was born in Arkansas and her father was a freight train conductor on the Missouri Pacific Railroad.

The idea that a major rail company would suddenly become an air freight company overnight is completely unthinkable. Railroads make most of their money hauling material in bulk, which includes vast amounts of coal. Not only would coal be impossible to ship by air, but so would other heavy bulk materials such as ore, steel, lumber, chemicals, grain, scrap metals, and even heavy machinery. Railroads excel at moving the most heaviest of goods efficiently and have yet to be proved obsolete by any other mode of transport in this field. The only competition air is to rail is that of passengers and time-sensitive mail and packages, but "Southland" is said to be doing only "air freight."
