GE B23-7 Diesel-Electric Locomotive
The GE B23-7 is a diesel locomotive model that was first offered by GE in late 1977. Featuring a smaller 12 cylinder version of the FDL engine, it is the successor to GE's U23B produced from early 1968 to mid 1977, but at 62 ft 2 in (18.95 m) long is exactly 2 ft 0 in (0.61 m). longer. It competed with the very successful EMD GP38-2. General Electric also produced a variant, the BQ23-7, no.5130-5139, for the Seaboard Coast Line. A total of 537 B23-7's were built for 9 U.S. customers and 2 for customers in Mexico.
A B23-7A is a 12-cylinder B23-7 with horsepower boosted to 250 per cylinder or 3,000 horsepower. In 1980 the Missouri Pacific ordered three B23-7A's (Nos. 4667-4669, later UP Nos. 257-259) and tested them system-wide. The result was the GE model B30-7A, B30-7 with a 12-cylinder FDL prime mover. They were not renumbered into the B30-7A series on the MP because they lacked Sentry Wheel Slip and had different engine governors.
13 B23-7's were built by GE of Brazil in December of 1979 for Ferrocaril Unidos del Sureste (FUS) Nos. 522-524 and National Railways of Mexico (NdeM) Nos. 9130-9139. 17 B23-7s were built from GE kits in Mexico as Ferrocarriles Nacionales de México (NdeM) Nos. 10047-10052 and Nos.12001-12011.
Southern Railway's 54 units had Southern's "standard" high-short-hoods.
These engines have frequently been rebuilt as Control Car Remote Control Locomotives (CCRCL) due to their low value on the used locomotive market.
