Union Pacific Railroad, recognized by its UP reporting mark, was founded in 1862 to build a transcontinental railroad connecting the central United States to the West Coast. Famous trains such as the City of San Francisco, the Overland Limited, and the City of Los Angeles continue to make Union Pacific trains for sale especially popular with collectors and model railroaders focused on western railroading, long-distance passenger service, and historic transcontinental operations.
UP locomotives, Big Boy steam engines, passenger cars, and freight equipment remain a favorite for layouts featuring western freight routes, mountain railroading, and modern diesel-era operations. These railroad models are commonly added to model trains centered on one of the most recognizable railroads in North American history.
