The GE B30-7 diesel-electric locomotive model was offered first by GE in 1977, featuring a 16 cylinder engine. 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 .
St Louis Southwestern (SSW), aka Cotton Belt #7784 in Rosenberg, Texas, January 5, 2001, very late in life.
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.
Cabless B30-7A were built only for the Burlington Northern Railroad. Shortline railroad Providence and Worcester Railroad acquired five ex-BN B30-7A cabless units, reclassified as B30-7AB units, numbered #3004-3008, in 2001. National Railway Equipment acquired these locomotives in 2015.
