A BRIEF HISTORICAL OVERVIEW OF THIS MODEL

Introduced in February 1952 and produced through November 1953, the SD7 was the 1500HP six axle big brother to the GP7. Riding on six axles, three-motor trucks, they were designed to offer more starting tractive effort in "road" service than the GP7. EMDs introduction of an A1A freight locomotive led them to design the SD7 from the ground up. In appearance, they are very similar to the GP7 only with a longer hood. The radiators are grouped together at the end of the long hood and not separated as was seen on the GP7. The grill assembly protrudes from the side of the hood whereas with the GP7 the grills are fit flush with the hood. As built, the SD7 very closely resembles the SD9 with the visual spotting features being the boarding steps and a variation of the classification lights. The SD7 (for Special Duty) was a massive locomotive at 60 feet 8 inches from coupler to coupler and weighing 360,000 pounds. It was powered by the same reliable 1500HP 567B V-16 two-cycle diesel engine as the GP7 and F7.
