U.S.R.A-design All-steel Box & Auto Cars (93 pages)
by Patrick C. Wider
The article is the fifth in a series that cover American box car designs that were built in large quantities during the first half of the 20th century. The article covers the U.S.R.A. all-steel box car design of 1918 and the ubiquitous box and automobile cars that were built in the post-World War I era that loosely followed this design. Included among the latter were the cars built for the New York Central Lines (New York Central, Boston & Albany, Cleveland, Cincinnati, Chicago & Saint Louis, Michigan Central, Peoria & Eastern, and Pittsburgh & Lake Erie) as well as the similar cars built for the Delaware, Lackawanna & Western, Reading, Central Railroad of New Jersey, and Universal Portland Cement Company. Railroads that received the latter’s cars second hand such as the Hannibal Connecting and Northampton and Bath are also covered. A total of 37,001 prototype cars of this description were built from 1920 to 1930. The article contains 147 page-width prototype and model photographs, eight diagrams, and three comprehensive tables.
The article covers the 2,000 steel cars built by the General American Transportation Corporation and American Car & Foundry Co. circa 1948-49 that were owned by the Armour Refrigerator Line (ARLX reporting marks) as well as the all-steel cars that were leased by Armour (TRAX and PCX reporting marks) in the mid-1950s. Contained in the article are 20 page-width photographs, eight diagrams, and three comprehensive tables.
