Model Information: During the first half of the 20th Century, the most common carrier for the transport of coal via rail lines was, in fact, the pervasive little 50-55 ton, twin-bay hopper. Ever-inventive engineers designed a different style of this essential hauler which became enormously popular with many Railroads by the 1930s and 40s. This "offset-side" hopper car had a few advantages over the earlier "rib-side" type. The crease in the upper sides led to more structural strength without using heavier materials, and there was a greater rated capacity with the side panels riveted to the outside of the ribbing, instead of being on the inside. The efficiency was a boon to the coal merchants! The concept proved successful, and was used to build ever-larger hoppers until after WW II, when "rivet pull-through" rendered it impractical for modern rotary dumping. Today, although they are seen less frequently, offset-side hoppers remain an important part of railroad history. Full Throttle presents a universal model of these unique hoppers.

Prototype History: The late 1920s saw the introduction of the AAR standard “offset-side” 50- and 70-ton hoppers. The design went through several variations in the late 1920s and early 1930s before settling on two versions of the 50-ton car and one 3-bay, 70-ton car in 1935. Most roads went for the AAR standard designs, but the N&W, VGN, and Pennsy were notable holdouts. World War II brought the famous “war emergency” hoppers (only the N&W and MP bought the 70-ton version) and several composite versions of existing designs. After the war, AC&F found some brief success with a welded outside-stake hopper design, but the weld joints broke under the stress of loading and unloading rather than flexing like riveted joints. The offset-side design also had problems: the inside stakes were more prone to corrosion, and they suffered worse from loading and unloading stress than outside-staked hoppers. The design waned in the 1950s and was all but abandoned for new cars by 1960. Some roads (notably the C&O, the B&O, and the L&N) made the best of a bad situation by rebuilding their offset-side cars with all new outside-staked sides in the late 1950s and early 1960s.

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: Greetings, I'm Will, a Fine Arts graduate of Kutztown University in Pennsylvania who grew up in the Delaware Valley. I worked for 30 years with the Pennsylvania German Folklife Society. For ten years I had a permanent booth, each month showing my "PA Dutch" wares, at the country's largest under-roof Antique Market in Atlanta, GA. When Mom and Dad started to have health issues, I was forced to give up the nomadic life, but during my travels I came to love Z Scale Model Railroading, as I could easily take small layouts with me to the motels and play with my trains in the evenings!
Now that Mom and Dad are gone, and after many years of providing care for my "Pappy" in Florida, I find myself a homebody in the "Sunshine State" with a neat little business, supplying interested Z hobbyists with rolling stock and unique quality products!
