GP7 units 101 and 123 are seen with a freight train through featureless terrain in 1969 in the red livery that the railroad used until 1971 when it adopted a green with yellow stripes scheme.
A total of 2,734 of the GP7 model were built by EMD between October 1949 and May 1954 and was the first to have the GP or General Purpose designation, which ended with the GP60 (see earlier post).
Like all the GP's they were Bo-Bo type. The diesel motor (prime mover) was an EMD 567B V16 rated at 1,500 horsepower (1,119 kW). Like other EMD units, the GP7 was offered in cabbed and cabless versions, the latter designated GP7B. The GP7's were the first EMD road units to use a hood unit design instead of a car-body design, considered more efficient with easier and cheaper maintenance, and offered visibility in both directions from the same cab.
