TheGE B30-7 is adiesel-electric locomotive model produced byGE from 1977 to 1983 as part of theirDash 7 Series, featuring a16 cylinder engine producing 3,000 horsepower. A total of 399 units were produced, including 120 cabless B30-7A units.[1] The B30-7AB/A(B) is an unofficial model. The B30-7 was GE's successor to theU30B.
The B30-7 was designed from theB23-7, and was nearly identical in appearance. However, the B30-7 featured 3,000 horsepower, compared to the B23-7's 2,300 horsepower. Almost all were built with FB2 trucks.[1]
GE produced several variants of the B30-7. These were developed from an experimental modification of the B23-7's 12-cylinder engine in June 1980 to uprate it to 3,000 horsepower. By using the 12 cylinder prime mover instead of the 16 cylinder version, railroads saved money on fuel and maintenance, and most subsequent B30-7s incorporated a 12-cylinder engine. Variants using this engine were the B30-7A, B30-7A1 and the cabless B30-7A. The B30-7A without a cab is unofficially known as the B30-7A(B) to distinguish it from the version with a cab.[1]
B30-7As were built only for theMissouri Pacific Railroad and are externally identical to the 16-cylinder version B30-7. B30-7A1s, which featured a high short hood, were built only for theSouthern Railway.
Cabless B30-7A(B)s were built only for theBurlington Northern Railroad.[1]
Shortline railroadProvidence and Worcester Railroad acquired five ex-BN B30-7A(B) cabless units, reclassified as B30-7AB units, numbered #3004-3008, in 2001.National Railway Equipment acquired these locomotives in 2015.[2] Most of the remaining B30-7A(B)s were retired in 1999.[1]
As of April 2024[update], two B30-7 or B30-7As remain inremote control master unit service on theUnion Pacific Railroad (out of the original 55 that were converted). As of the same time, multiple units also remain on theMinnesota Commercial Railway andWest Tennessee Railroad, while theNatchez Railway was attempting to sell theirs.[3]
