Micro-Trains - 55120 - Open Hopper, 2-Bay, Offset Side - Texas and Pacific - 9004

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 Texas and Pacific Railway Company (known as the T&P) was created by federal charter in 1871 with the purpose of building a southern transcontinental railroad between Marshall, Texas, and San Diego, California. The T&P had a significant foothold in Texas by the mid-1880s. Construction difficulties delayed westward progress, until American financier Jay Gould acquired an interest in the railroad in 1879. The T&P never reached San Diego; instead it met the Southern Pacific at Sierra Blanca, Texas, in 1881. The Missouri Pacific Railroad, also controlled by Gould, leased the T&P from 1881 to 1885 and continued a cooperative relationship with the T&P after the lease ended. Missouri Pacific gained majority ownership of the Texas and Pacific Railway's stock in 1928 but allowed it to continue operation as a separate entity until they were eventually merged on October 15, 1976. On January 8, 1980, the Missouri Pacific Railroad was purchased by the Union Pacific Railroad. Because of lawsuits filed by competing railroads, the merger was not approved until September 13, 1982. However, due to outstanding bonds of the Missouri Pacific, the actual merger with the Union Pacific Railroad took place on January 1, 1997.From Wikipedia

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.
