The Atlas HO Master 50' AAR Plug Door Box Car Union Pacific 499020 models the 50' plug door box car. The plug (flush) style sliding door allows for a larger door for improved loading and unloading. The "plug" door enables a very tight fit which provides a more even temperature inside the car. By adding insulated sides, ends and floors allowed certain perishables to be carried in unrefrigerated box cars. This design, the AAR (Association of American Railroads) "RB" or "RBL", designated bunkerless refrigerator cars, were produced in the 1950s. Over 3,000 were built for North American railroads.
Road Name and History:
Union Pacific Railroad: This railroad is a big part of 19th Century US history, and is still an important part of the economy today. Legislation creating the Union Pacific was signed by President Abraham Lincoln- UP would be the eastern end of the first transcontinental railroad. In one of the most important events of the 19th Century the transcontinental railroad was completed in 1869. Celebrations were tough on the Union Pacific, where mismanagement, waste, and corruption made the company anathema to many Americans. Excellent leadership first under Jay Gould and then E. H. Harriman propelled this lagging railroad into a premier US railroad. Mr. Harriman's philosophy of pumping cash back into the railroad worked wonders, and the Union Pacific became a very successful railroad throughout the 20th Century. The merging during the 1980s and 1990s of key Western railroads Missouri Pacific, Chicago & North Western, and Southern Pacific (among many more) has positioned this huge railroad to be one of the two megasystems operating in the Western US.
Travel Tip: Driving US Highway 30 across Nebraska will enable you to follow Union Pacific Railroad's Transcontinental Main Line for hundreds of miles. Make sure to visit the Golden Spike Tower at UP's huge Bailey Yard in North Platte, NE.
