The Atlas HO Master 1932 ARA Box Car Soo Line 135800 models the 1932 ARA box car. The American Railroad Association (ARA), the agency that managed the US railroads during World War I on behalf of the US Government, sought in the 1920s to design a new all steel box car that could serve as a standard for the industry. First introduced in 1923, it was not until the 1932 all steel box car was introduced did the railroads accept a standardized design. Although later designs, such as the 1937 AAR design would prove more popular, the 1932 car was truly revolutionary. For the first time, railroads bought a box car "off the shelf" with all railroads using basically the same design. Previously Mechanical Department's had specified individual designs per railroad.
Road Name and History:
Soo Line Railroad: The consolidation of several smaller railroads in Wisconsin and Minnesota in 1961 created Canadian Pacific Railway subsidiary Soo Line Railroad, which became CP's Bridge Route from Chicago to Western Canada. In 1985 Soo Line purchased the routes of the Milwaukee Road, and then in 1986 in turn spun off most of the old Soo Line to Wisconsin Central, now merged with Canadian National. In the 2000s Soo Line's identity has faded away into parent Canadian Pacific
