Experience the largest, most powerful diesel locomotives ever built. The Union Pacific DDA40X Centennials weighed in at 270 tons, were close to 100 feet long (98 feet 5 inches), carried an 8,000-gallon fuel tank, had 16-cylinder dual power plants that could generate 6,600 horsepower, and attained speeds of up to 90 mph. 47 of these behemoths were built for the Union Pacific by the Electro-Motive Division of GMC between 1969 and 1971. Within 5 years of service, most of these units had racked up over 1,000,000 miles of duty, predominantly on UP’s high-speed western states mainline freights.
Powerful as they were, the “Big Jacks” were also high maintenance locomotives and by the early 1980s were being phased out of duty. In this award-winning video, originally released by Video Rails, you’ll witness the Centennials traveling through all types of terrain across 5 different states. Thrilling scenes feature them in operation on Sherman Hill, in the Feather River Canyon, and even over Cajon Pass. Fantastic pacing sequences add to the excitement. Plus, a special treat is a cab ride in a Centennial racing along at 90 mph! There was nothing quite like the sights and sounds of UP Centennials on the rails. Here is your chance to see them at their very finest.
