Inscription. Locomotive 6900 was one of 47 "DDA-40X" locomotives built by the Electro-Motive Division of General Motors exclusively for Union Pacific and according to Union Pacific specifications. These "Centennial" locomotives were built in 1969 when Union Pacific was celebrating the 100th anniversary of the driving of the Golden Spike to complete the nation's first transcontinental railroad.

The 6600-horsepower Centennials, designed when the tonnage of freight trains was increasing dramatically, were built to carry heavier loads farther, faster, and with less maintenance. They are the world's largest single-unit diesel locomotives, requiring four axle trucks to distribute their weight within track loading limits. Powered by two diesel engines, Centennials could reach 85 miles per hour on level track. Power was transmitted to the wheels through eight electric traction motors, one for each set of wheels. The Centennials hauled freight throughout the Union Pacific system from 1969 until 1984.

Locomotive 6900 was the first Centennial produced. It left Omaha on its first run in May 1969, bound for Ogden, Utah, and the celebration of the 100th anniversary of the Golden Spike. It was retired after logging nearly 2 million operating miles. The last operating Centennial, Locomotive 6936, continues to operate as part of Union Pacific's
