Micro-Trains - 21140 - Boxcar, 40 Foot, Steel Plug Door - Union Pacific - 113596

Prototype History: Plug-Door boxcars are usually insulated and typically carry products such as canned goods that require protection from extremes of temperature but do not require refrigeration. Plug-style doors were normally used to ensure a tight seal in the insulation. Designed for transport of both perishables and large loads, plug doors allowed box cars to be sealed from outside dust and dirt. Cars like these were manufactured during the 50s and 60s.

Whether you consider this a reefer or a boxcar is a matter for angel-pinhead-counters. There seems to be a bit of a blurry line during the transition era between the idea of a steel ice reefer and an insulated boxcar. I guess an ice reefer was meant to hold ice for cooling but I doubt this is a cut-and-dry distinction. Modern "mechanical" reefers are a different breed as they contain a refrigeration unit which quite distinctly sets them apart from "boxcars".

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: 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.
