Built in 1963 by the General Electric Company, this U25B diesel was acquired by the Southern Pacific as SP 7508 for freight service. Later numbered SP 6800,it became SP's Bicentennial engine in celebration of the nation's two hundredth birthday. The final numbering, SP 3100, is shown here. This locomotive is operational and is used in regular demonstration railway service. The two axle trucks and 2500 HP diesel engine also makes this engine an ideal candidate for motive power on occasional off property OERM work trains.
