Equipment Information

Union Pacific 6930 is the most powerful diesel-electric locomotive at the museum. It is one of 47 identical locomotives built exclusively for the UP and called “Centennials” because they were delivered starting around the 100th anniversary of the “Golden Spike” that completed the UP’s transcontinental railroad. The locomotive features two separate diesel engines, or “prime movers,” and eight powered axles.
