The GE B30-7 diesel-electric locomotive model was offered first by GE in 1977, featuring a 16 cylinder motor. It is 61 ft 2 in (18.64 m) long. A change to the original B30-7 was using the 12 cylinder FDL rated at 3,000 horsepower (2,200 kilowatts), resulting in a B30-7A, B30-7A1 and a cabless B30-7A .
B30-7As were built only for the Missouri Pacific Railroad and are externally identical to the 16 cylinder version B30-7.
B30-7A1s were built only for the Southern Railway.
