The Atlas HO Master 50' AAR Plug Door Box Car Western Pacific 56074 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:
Western Pacific Railroad: The Western Pacific Railway was built as a result of E. H. Harriman gaining control of the Southern Pacific Railroad, that closed the Ogden Gateway to George Gould's Denver & Rio Grande Western. The WP was incorporated in 1903 and the last spike of the Salt Lake City-Oakland route was driven near Keddie, CA, in 1909. The line through the Sierra Nevada Mountains followed the Feather River thus earning WP the name "The Feather River Route". The Western Pacific, Rio Grande, and many other Gould roads went bankrupt in 1915- the Western Pacific Railroad emerged from bankruptcy in 1916 as the Western Pacific Railroad. In 1931 the Inside Gateway route was completed as Western Pacific built north from Keddie to reach the Great Northern at Bieber,CA. A scrappy smaller railroad surrounded by huge rail systems, the Western Pacific was swallowed by the Union Pacific Railroad in 1981. With UP's purchase of the Southern Pacific, the SP's Donner Pass line has been favored over the former WP Feather River Route.
Historical Fact: After World War II the Western Pacific teamed with the Burlington and Rio Grande to create the Chicago-Oakland (Ferry later bus to San Francisco) Vista-domed California Zephyr, perhaps the most famous of the PostwarStreamliner trains.
