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.
With
a maximum speed range between 55 and 89 miles per hour, depending on the
gearing ratio selected, and a tractive force of 90,000 pounds, the SD series
was here to stay. With the SD7, EMD introduced the "lightweight"
Flexicoil truck which enabled these locomotives to be used on branchlines as
well as for road service. These trucks were so smooth that the SD7 was compared
to "riding in a luxury car." With the advent of 1954, EMD made a
conservative marketing push against the competition with the announcement of
their "Nine Line" series. This consisted of the introduction of new
locomotive model numbers, the SW9/1200, the F9A/B, the GP9, and the SD9.
