SSW® is a registered trademark of the Union Pacific Railroad.
Built in 1958, this insulated plug-door 40’ boxcar with Roller Bearing trucks was Compartmentizer- equipped and was used to transport temperature sensitive commodities such as food and some household products. St. Louis Southwestern, commonly known as Cotton Belt, was founded in 1891 and became a Southern Pacific subsidiary in 1932, before eventually fully merging in 1992. It is now a heritage component of Union Pacific.
