Prototype History: The USRA 55-Ton hopper was designed by the United States Railway Administration during World War I as a standardized hopper to be used by all railroads in order to aid the war effort. After WWI many railroads continued to use the USRA 55-Ton hoppers, as well as build many thousands more clones. The USRA hopper was in use on North American railroads from 1918 until the 1970’s

Brand/Importer Information: Micro-Trains is the brand name used by both Kadee Quality Products and Micro-Trains Line. For a history of the relationship between the brand and the two companies, please consult our Micro-Trains Collector's Guide.

Manufacturer Information: Kadee Quality Products originally got involved in N-Scale by producing a scaled-down version of their successful HO Magne-Matic knuckle coupler system. This coupler was superior to the ubiquitous 'Rapido' style coupler due to two primary factors: superior realistic appearance and the ability to automatically uncouple when stopped over a magnet embedded in a section of track. The success of these couplers in N-Scale quickly translated to the production of trucks, wheels and in 1972 a release of ready-to-run box cars.
In October 1990 Kadee separated in two companies, with the newly created Micro-Trains® Line Co. continuing the Z, Nn3, and N Scale product ranges, with Kadee retaining the HO range.
