An SD45-2 is a 6-axle diesel-electric locomotive built by General Motors Electro-Motive Division beginning in 1972. It had an EMD 645E3 20-cylinder engine producing 3,600 horsepower (2,680 kW). Part of the EMD Dash 2 line, the SD45-2 was an upgraded SD45. The main spotting difference between an SD45 and an SD45-2 was the long hood and the rear radiator. On the SD45 the long hood is flared whereas on the SD45-2 it is vertical and the rear cooling fans are more spread out on the top of the rear of the long hood. This unit used the same frame as the EMD SD40-2 and EMD SD38-2. The largest owner of the SD45-2 was the Atchison, Topeka, & Santa Fe with 90 units, the Clinchfield had 18 units, Seaboard Coast line had 15 units and Erie Lackawanna rostered 13 units.
A few cabless SD45-2Bs were built by Santa Fe, rebuilds of wrecked units. In most cases, 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. With no cab, these B-units are controlled from other locomotives. Santa Fe acquired more B units than any other railroad in North America.
