PROTOTYPE SPECIFIC INFORMATION

An EMD SW1500 is a 4 axle diesel switcher locomotive built by General Motors Electro-Motive Division between 1966 and 1974. It is similar in appearance to the EMD SW1000 model, which has a different engine and has one exhaust stack while the SW1500 has two.

Power was provided by an EMD 645E 12-cylinder engine which generated 1,500 horsepower. This locomotive was built on the same common frame as the EMD SW1000, giving it an overall length of 44 feet 8 inches.

The SW1500 featured a bulkier carbody and was a bit heavier from earlier models although its intended use remained the same, working light branch lines or in industrial settings. Many railroads regularly used SW1500s for road freight service.

Southern Pacific

Between 1967 and 1973, Southern Pacific purchased one of the largest orders of SW1500’s with over 200 units to help replace their aging fleet of Alco, Baldwin, and FM switchers. Unique SP spotting features included a large cab-front mounted number board and SP’s full front and rear lighting package. In the mid 1980’s, two SW1500’s (2539 and 2575) were repainted in the red and yellow “Kodachrome” scheme in anticipation of a merger with Santa Fe. Both schemes were slightly different from another and only 2575 lasted in this scheme, retired just before the UP merger of 1996. As many were sold off for further use after the merger, UP retained some for use in areas with lighter track and local switch jobs that needed smaller motive power.

SP FEATURES:

• Flexicoil Trucks

• Large fuel tank

• Frame-mounted handrails

• SP light package

• Whip antenna

• MU hoses

• Nathan P-3 horn

• Footboards where appropriate
