Micro-Trains - 22030 - Boxcar, 40 Foot, Steel Combo Door - Union Pacific - 110023

Prototype History: The plug-and-sliding-door or combo-door boxcar is a versatile car that can act as either a double door boxcar or a plug door boxcar. If you were loading 8' studs in the car, you would load the car just like any other double door boxcar. But if you are loading paper, you would seal the far doors with duct tape, load the car and close the slider. Seal the slider with duct tape, and then shut the plug door to seal the car.

The main reason all the large box cars today have mostly plug doors, is that large sliding doors just get too hard to move. Trying to open regular 8' sliding doors, unless the cars were fairly new, is quite challenging. After a sliding-door car was several years old, you'd see where the sliding door was getting all banged up from people using forklift blades to open and close the doors. Plug doors, however, run on wide runners and rollers, and are therefore easier to move. Also, since the doors are out away from the car side, there is no problem when a car side becomes bulged out due to wear and tear.

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.
