Prototype History: An SD40T-2 is a 6-axle diesel-electric locomotive built by General Motors Electro-Motive Division having a 16-cylinder EMD 645E3 diesel engine producing 3,000 horsepower (2,240 kW). 312 SD40T-2s were built for North American railroads between April 1974 and July 1980. This locomotive and the SD45T-2 are popularly called tunnel motors, but EMD's term is SD40-2s with "cooling system modifications" because they were designed for better engine cooling in tunnels. The difference between this locomotive and its non-tunnel motor cousin, the SD40-2, are the radiator intakes and radiator fan grills located at the rear of the locomotive. The radiator air intakes in this model were along the deck to allow more fresh, cooler air to enter and less hot exhaust fumes lingering around the tunnel's ceiling.

This locomotive model was purchased by the Denver and Rio Grande Western Railroad, the Southern Pacific Railroad, and its subsidiary Cotton Belt. Southern Pacific's version has a 4,400-US-gallon (16,700 L; 3,660 imp gal) fuel tank and is 70 feet 8 inches (21.54 m) long. Rio Grande's version has a smaller 4,000-US-gallon (15,100 l; 3,330 imp gal) fuel tank. After merging with Rio Grande, the Southern Pacific and later Union Pacific owned every SD40T-2.

In 2005, most of these units were owned by Union Pacific or leasing companies. By 2008, none were left in service on UP with SP or DRGW reporting marks. DRGW 5371 was the last one, retired in March 2008, and now resides at the Utah State Railroad Museum in Ogden Utah. Another SD40T-2 is preserved at the Boone & Scenic Valley Railroad in Boone, Iowa. UP still runs a few units repainted in its own livery.

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: ScaleTrains.com, Inc. is an upstart HO and N Scale model manufacturer that was founded by a team with more than 125 years of accumulated experience in the model railroad hobby and industry.

ScaleTrains is specifically focused on the tiny details in the printing and quality of the construction. The four friends who founded the company are all avid modelers themselves. Their factory is located in Tennessee. Unlike most other companies, they offer a range of different levels of complexity in their offerings so as to be able to provide products for both the budget-conscious collector as well as the detail-focused model enthusiast without compromising on quality for either.

They range covers the following, by increasing level of detailing:

1. Operator™ trains are built for modelers who enjoy running high-quality, realistic trains at an affordable price. Designed from builder’s drawings and photographs, Operator models have fewer factory-applied parts and simplified printing. For added versatility, super-detail parts are available separately.
2. The Rivet Counter™ line strives to create the most accurately detailed models imaginable. The real-world counterpart is meticulously researched to ensure prototype fidelity. Each model features numerous factory applied parts including roadname and road number specific details whenever possible.
3. Museum Quality™ models are historically accurate replicas of the most famous locomotives in North American railroading history. Exhaustive research and a commitment to perfection combine to create the ultimate scale model. Museum Quality trains establish new standards which make them just as legendary as the original.
