An EMD SD45-2 is a 6-axle diesel locomotive built by General Motors Electro-Motive Division beginning in 1972. Power was provided by an EMD 645E3 20-cylinder engine which generated 3600 horsepower (2.7 MW). Part of the EMD Dash 2 line, the SD45-2 was an upgraded SD45.The main spotting difference between an SD45 and a SD45-2 was the long hood configuration and the rear radiator assembly. On the SD45 the long hood is flared whereas on the SD45-2 it is vertical and the rear cooling fans and more spread out over the top of the rear of the long hood. This unit shared the same common frame with the EMD SD40-2 and EMD SD38-2.

A few cabless SD45-2Bs also existed; these were rebuilds of wrecked units. As in the example shown, the dynamic brakes were moved to the opposite end of the hood from the radiators; they were originally near the center of the hood.
