Micro-Trains - 108 52 101 - Open Hopper, 3-Bay, 100 Ton - Union Pacific - 18141

Specific Item Information: These Union Pacific 100 Ton, 3-Bay hoppers in series 17950-18199 were built by Bethlehem steel in 1962. They are class H-90-1 and feature Barber roller bearing trucks.

Model Information: Micro-Trains launched this body style in April of 2000. Since then it has appeared in over 100 different regular releases (including multi-packs) as well as special runs. It features truck-mount couplers on barber trucks. These cars model prototypes that were built in in the late 1970s and 1980s.

Prototype History: The 1960s brought about a growth in car size (and capacity). Railroads that transported coal moved away from the older 2-bay 55-ton USRA standard to newer 90- and 100-ton three bay hoppers. On the WM, the first 90 ton cars were purchased for stone service to Sparrows Point around 1963. These cars were effective and long-lived. Many railroads swapped out the trucks on these cars to increase the capacity to 100 tons. Many companies produced these, including Pullman, Bethlehem, Evans, Greenville, Trinity and Ortner. Details, of course, vary from manufacturer to manufacturer, but typically they were rib-sided. As of 2007, the NS still had lots of 90 ton hoppers in coal service.

Road Name History: The Union Pacific Railroad (reporting mark UP) is a freight hauling railroad that operates 8,500 locomotives over 32,100 route-miles in 23 states west of Chicago, Illinois and New Orleans, Louisiana. The Union Pacific Railroad network is the largest in the United States and employs 42,600 people. It is also one of the world's largest transportation companies.

Union Pacific Railroad is the principal operating company of Union Pacific Corporation (NYSE: UNP); both are headquartered in Omaha, Nebraska. Over the years Union Pacific Corporation has grown by acquiring other railroads, notably the Missouri Pacific, Chicago & North Western, Western Pacific, Missouri-Kansas-Texas, and the Southern Pacific (including the Denver & Rio Grande Western).

Union Pacific Corporation's main competitor is the BNSF Railway, the nation's second largest freight railroad, which also primarily services the Continental U.S. west of the Mississippi River. Together, the two railroads have a duopoly on all transcontinental freight rail lines in the U.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: Micro-Trains Line split off from Kadee Quality Products in 1990. 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.

Micro-Trains Line Co. split off from Kadee in 1990 to form a completely independent company. For this reason, products from this company can appear with labels from both enterprises. Due to the nature of production idiosyncrasies and various random factors, the rolling stock from Micro-Trains can have all sorts of interesting variations in both their packaging as well as the products themselves. When acquiring an MTL product it is very important to understand these important production variations that can greatly enhance (or decrease) the value of your purchase.
