DCC AND SOUND EQUIPPED MODEL

Built by EMD exclusively for Union Pacific between 1969 and 1971, the DDA40X Centennial locomotives were the modern equivalent of the railroad's famed Big Boy steam locomotives. These massive 98-foot double-engine diesels were UP's mainstay hotshot power for a decade until they were sidelined by the recession of the early 1980s. They had one last hurrah in 1984-85 when 25 of the them were returned to service for about a year to help relieve a power shortage.
