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 Mexican customers.

13 B23-7's were built by GE of Brazil in Dec.1979 for United South Eastern Railways(FUS) no.522-524 and National Railways of Mexico(NdeM) no.9130-9139. 17 B23-7s were built from GE kits in Mexico as Ferrocarriles Nacionales de México no.10047-10052 and no.12001-12011.

Southern Railway's 54 units had Southern's "standard" high-short-hoods.

These engines frequently are rebuilt as Control Car Remote Control Locomotive (CCRCL) due to their low value on the used locomotive market.
