Editing Autorack (section)

===Trailer Train Company===
Although railroads were just beginning to see the advantages that autoracks delivered in the 1960s, most North American railroads were reluctant to invest in such specially built equipment. The [[TTX Company|Trailer Train Company]], organized by the [[Pennsylvania Railroad]] and the [[Norfolk and Western Railway]] in 1955, stepped in to ease the railroads' financial burden a bit. Trailer Train purchased the flat cars from the rail car manufacturers, and the railroads that wanted to operate autoracks, purchased the racks that were installed on those flat cars. Such cars were easily spotted at trackside due to the reporting marks identifying Trailer Train on the flat car portion of the car and the railroad's logo (usually much larger) in the upper portion of the rack.

This arrangement worked so well that nearly every autorack operating in the US was owned by a railroad, with only a few exceptions. Trailer Train became [[TTX Company]] in 1991; since then many railroads have themselves purchased the flat cars on which the racks were installed and TTX has itself expanded into purchasing and leasing out other railroad [[rolling stock]]. The development of enclosed autoracks also helped make several other innovative services work well.
