Steam MT-73 4-8-2 w/Oil Tender, Powered w/Sound -- Union Pacific (Unlettered, silver Striping, 2-Tone gray)

As faster schedules and heavier trains taxed Pacifics and Mikados, Union Pacific ordered a 4-8-2 for testing in 1922. When #7000, the first of the new MT class arrived for inspection, designer A.H. Fetters remarked that here was a real sporty model and the nickname "sport model" stuck. With its 73" drivers, big boiler and plenty of power, #7000 impressed officials so much that 44 additional MTs were ordered. In the years that followed, the locos were rebuilt and modernized several times. In 1946, they were repainted in the new gray passenger power scheme, but went back to standard black after 1950. Despite the arrival of bigger and better power, the 4-8-2s continued to turn in an impressive record and the last was withdrawn from service in 1956. These models are patterned after rebuilt versions and feature a disc main driver, Walschaerts valve gear and "Sweeney" stack. Each comes with a detailed replica of the original 12000-gallon Semi-Vanderbilt coal tender riding
