The GE U23B Diesel-electric locomotive was introduced by GE Transportation in 1968 as a medium horsepower roadswitcher, featuring a 12 cylinder FDL engine. It was one of the most successful models of the Universal Series, with railroads ordering it from 1968 until 1977 when it was replaced by the B23-7. 481 units were built, including 16 exported to Peru.
Not many U23Bs still exist, but a few shortline and regional railroads such as the Georgia Central Railway still have several U23Bs in everyday service.
CR 2798 was the last U23B built by GE in 1977, and the last Universal Series locomotive built for
North American use. In this photo, it is leading a westbound train through
Middlefield, Massachusetts, in June 1979.
