Model Information: Rivarossi first introduced this model in 1980. There have been a couple of different versions of this model over the years. The first version (often found in boxes labeled "Premiere Edition") came equipped with Rivarossi's dodgy"can" motor. They do, however, look pretty nice. In 1988 these models were updated to use a 3-pole skew-wound motor. The newer mechanism worked much better and due to some innovative plastic driveshaft tech, they run much more smoothly and quietly.

This engine was only imported to the United States by Con-Cor, although Rivarossi did also sell some with their own branding ('Minitrain') in Europe.
DCC Information: No provision for DCC.

A DCC decoder installation for this model can be found on the TCS website.
Prototype History:
Big Boy is the popular name of the American Locomotive Company 4000-class 4-8-8-4 articulated, coal-fired, steam locomotives manufactured between 1941 and 1944 and operated by the Union Pacific Railroad until 1959.

The Big Boy fleet of twenty five locomotives were used primarily in the Wyoming Division to haul freight over the Wasatch mountains between Green River, Wyoming and Ogden, Utah. They were the only locomotives to use a 4-8-8-4 wheel arrangement consisting of a four-wheel leading truck for stability entering curves, two sets of eight driving wheels and a four-wheel trailing truck to support the large firebox.

According to Union Pacific senior manager of Heritage Operations Ed Dickens Jr., the 4-8-8-4 series originally was to have been called "Wasatch". One day while one of the engines was being built an unknown worker scrawled "Big Boy" in chalk on its front. With that, the legendary name was born and has stuck ever since.

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.
