Southern Pacific 3100 is a GE U25B/GE U25BE diesel-electric locomotive now on permanent exhibit at the Southern California Railway Museum, formerly the Orange Empire Railway Museum in Perris, California, US. [2] It is notable as being the only U25B still in operating condition.

Construction and service

Built in 1963 by General Electric under construction number 34700, it was shipped from GE's Erie, Pennsylvania, locomotive assembly plant to the Southern Pacific Railroad on March 29, 1963. [3] [4] [5] It entered service in April and was assigned to the Los Angeles Freight Pool with Taylor Yard Roundhouse as its maintenance point.

The locomotive was first numbered SP 7508, [4] then renumbered SP 6708 during the railroad's 1965 general renumbering. After a period of storage in the early 1970s, the U25B was moved to the Sacramento General Shops in 1975 for a complete rebuilding, one of only two U25Bs so done. The work included upgrading the prime mover with later GE U33C-compatible parts, a complete rewiring of the high- and low-voltage electrical systems, the installation of an AAR control stand and a new number - SP 6800. It was released from Sacramento on September 29 and returned to service.

The U25B became a "goodwill ambassador" for the railroad in 1976 when it was painted in an elaborate red, white, and blue color scheme in celebration of the nation's bicentennial, one of four Southern Pacific locomotives so painted. [3] [6] The others were GS-4 4449, EMD GP40P-2 3197, and EMD SD45T-2 9389. After the bicentennial celebration, it was repainted in the standard red and gray SP color scheme. In late 1977, 6800 was assigned to local and hauler service in the Los Angeles Basin, primarily working out of Taylor Yard in Los Angeles and West Colton Yard. In June 1979, it received its final renumbering as SP 3100. In and out of storage for the rest of its time with the railroad, 3100 was finally retired on December 17, 1986, and sold serviceable to Levin Metals in Colton on January 22, 1988.

Preservation

On February 2, 1988, 3100 was donated in operable condition to the Orange Empire Railway Museum. It was used for excursion passenger service regularly in the museum and even onto old ATSF trackage for longer excursions (now repurposed by SCAX)The locomotive was repainted and restored in between mid-2009 and 2010. It is still operating today on daily trains. [4] [7]

From 1940 through 1953, GE participated in a design, production, and marketing consortium (Alco-GE) for diesel-electric locomotives with the American Locomotive Company. In 1956 the GE Universal Series of diesel locomotives was founded for the export market. The U25B was the first attempt at the domestic market since its termination of the consortium agreement with Alco.

Southern Pacific 9010 is a KM ML 4000 C'C' diesel-hydraulic locomotive, built in 1964 by German manufacturer Krauss-Maffei for the Southern Pacific Railroad. SP 9010 generated 4,000 horsepower (3,000 kW) from two 2,000-horsepower (1,500 kW) V16 Maybach MD870 diesel engines. It was painted to Southern Pacific's 1958 standard, the so-called "bloody nose" colors of Scarlet and Lark Dark Gray, for its entire operating career. It was renumbered to SP 9113 in late 1965, rebuilt extensively at SP's Sacramento General Shops during the latter half of 1966, and was initially retired in 1968. It was revived and rebuilt by Sacramento General Shops into a "camera car" for the purpose of shooting motion picture background plates for a ground-based full-motion locomotive training simulator. As camera car number 8799, it was retired in 1984 and donated to the California State Railroad Museum in Sacramento, California. It was de-accessioned by CSRM and acquired by the Pacific Locomotive Association and moved to the Niles Canyon Railway's Brightside, California rail yard in the summer of 2008. At the date of its inception, its type represented the highest-horsepower six-axle diesel locomotives in the world. SP 9010 is the sole surviving ML 4000 C'C' built for use in North America, and the sole surviving mainline diesel-hydraulic locomotive in North America..
