HO DDA40X Locomotive, UP #6901

UP FEATURES:

• Beacon (Flash function in DCC only)
• Classification lights (Function in DCC only)
• Number board lights
• Working Truck lights
• Separate see-through walkways
• MU hoses

Built exclusively for Union Pacific by EMD between 1969 & 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 1980’s. They had one last hurrah in 1984-85 when 25 of them were returned to service for about a year to help relieve a power shortage.

ROAD NUMBER SPECIFIC FEATURES:

• The only DDA40X to be built without class lights on the long hood. It was delivered in time for the Golden Spike Centennial Celebration
• thus earning the series the moniker ‘Centennial’. This model represents the ‘as-delivered’ appearance. Currently preserved and prominently displayed in Omaha
• NE alongside Big Boy #4023.

• Unique chicken-wire-esque radiator grilles on the long hood for both prime movers, the only DDA40X equipped like this. #6905 (previously released by Athearn) had one set of these grills and were mismatched with the traditional grill. #6901 is Primed for Grime to match its last years in service appearance. Currently preserved and on display in Pocatello, ID.
