Micro-Trains - 55090 - Open Hopper, 2-Bay, Offset Side - Burlington Northern - 502341

Specific Item Information: 55091 is the Rapido Coupler Version

Model Information: The 33' Offset-Side open hopper was introduced in 1979. It is known by collectors as body style '055' or '55000 Series'. This model has been produced in over 100 different varieties since then, making it a fairly popular body style. Newer versions may come with a factory supplied load and low profile wheels.

Prototype History: The late 1920s saw the introduction of the AAR standard “offset-side” 50- and 70-ton hoppers. The design went through several variations in the late 1920s and early 1930s before settling on two versions of the 50-ton car and one 3-bay, 70-ton car in 1935. Most roads went for the AAR standard designs, but the N&W, VGN, and Pennsy were notable holdouts. World War II brought the famous “war emergency” hoppers (only the N&W and MP bought the 70-ton version) and several composite versions of existing designs. After the war, AC&F found some brief success with a welded outside-stake hopper design, but the weld joints broke under the stress of loading and unloading rather than flexing like riveted joints. The offset-side design also had problems: the inside stakes were more prone to corrosion, and they suffered worse from loading and unloading stress than outside-staked hoppers. The design waned in the 1950s and was all but abandoned for new cars by 1960. Some roads (notably the C&O, the B&O, and the L&N) made the best of a bad situation by rebuilding their offset-side cars with all new outside-staked sides in the late 1950s and early 1960s.

Road Name History: The Burlington Northern Railroad (reporting mark BN) was a United States railroad. It was a product of a March 2, 1970, merger of four major railroads - the Great Northern Railway, Northern Pacific Railway, Spokane, Portland and Seattle Railway and the Chicago, Burlington and Quincy Railroad - as well as a few small jointly owned subsidiaries owned by the four.

Burlington Northern operated between 1970 and 1996.

Its historical lineage begins in the earliest days of railroading with the chartering in 1848 of the Chicago and Aurora Railroad, a direct ancestor line of the Chicago, Burlington and Quincy Railroad, which lends Burlington to the names of various merger-produced successors.

Burlington Northern purchased the Atchison, Topeka and Santa Fe Railway on December 31, 1996 to form the Burlington Northern and Santa Fe Railway (later renamed BNSF Railway), which was owned by the Burlington Northern Santa Fe Corporation.*

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.
