GE U30B Ph2

Technical Specifics

The GE U30B was a four-axle diesel-electric road switcher built by General Electric Transportation between 1966 and 1975. It represented a natural progression within GE's Universal series, following the U28B and offering an increase in output to 3,000 horsepower. In total, 296 units were constructed over the model's production run, making it a moderately successful entry in what was an increasingly competitive market for high-horsepower four-axle locomotives during the late 1960s and early 1970s. During its production years, the U30B competed directly against the Electro-Motive Division's GP40 and, to a lesser extent, the Alco Century 430. The GP40 proved to be the more popular choice among many Class I railroads, and the U30B never achieved the same level of commercial success as its six-axle counterpart, the U30C, which found considerably wider acceptance. Nevertheless, the U30B attracted a respectable roster of buyers among North American railroads that valued GE's robust construction and the performance characteristics of the Universal series platform. The U30B's legacy is tied to GE's broader effort to establish itself as a serious competitor to EMD in the high-horsepower road locomotive market. The lessons learned from the Universal series, including the U30B, helped inform the development of GE's subsequent Dash 7 line, which would ultimately prove far more commercially dominant. At least one example of the model survives in preservation, with Western Pacific 3051 on display at the Western Pacific Railroad Museum in Portola, California, having been donated by Union Pacific in 1985.
