The SD45T-2 is a model of diesel-electric locomotive built by EMD for the Southern Pacific Railroad.Like the later SD40T-2 it is colloquially nicknamed a tunnel motor. 247 total units (including the original EMD/SP joint venture working Prototype) were produced from February 1972 to June 1975, including 84 for SP's subsidiary Cotton Belt.
The EMD SD45-2 is a 6-axle diesel-electric locomotive built by General Motors Electro-Motive Division (EMD). EMD built 136 locomotives between 1972 and 1974, primarily for the Atchison, Topeka and Santa Fe Railway (ATSF). The SD45-2 was an improved version of the EMD SD45; the primary visual difference is the absence of flared radiators on the ...

A total of 1,260 were built for American railroads before the SD45-2 replaced it in 1972, along with the related SD45T-2 'Tunnel Motor'. [citation needed] SD45s had several teething problems. Reliability was not as high as anticipated; the twenty-cylinder prime mover was prone to crankshaft failure from engine block flex.
The SD40T-2 is a model of diesel-electric locomotive built by General Motors Electro-Motive Division in the United States. The SD40T-2 is equipped with a 16-cylinder EMD 645E3 diesel engine producing 3,000 horsepower (2,240 kW). 312 SD40T-2s were built for three railroads in the United States between April 1974 and July 1980.

The SD38-2 and SD40-2 shared the same basic superstructure, since they used the same 16-645 engine (in Roots-blown and turbocharged form respectively); the long hood was 18 inches (457 mm) longer than the SD38 and SD40, but since the increase in frame length was even greater, the SD38-2 and SD40-2 had even larger front and rear "porches" than ...
In addition, many other earlier locomotives were rebuilt to Dash 2 standards by numerous locomotive rebuilders and railroad shops. Among the most popular rebuilds are SD40, SD45, SD40T-2 and SD45T-2 into the functional equivalent of an SD40-2, although the frame, carbody and trucks remain the same as on the "donor" locomotive. In many cases ...
