Not many U23Bs still exist, but a few shortline and regional railroads still use them in everyday service. The
Georgia Central Railway was one of the last U23B holdouts, rostering almost all of the remaining ex
Southern Railway (U.S.) high short hood U23Bs. The Georgia Central as of July 2015 has all of its U23Bs off of the roster with the 3965 going to the
Southern Appalachia Railway Museum in Oak Ridge, TN. Another U23B,
CSX 9553, former
L&N 2817, is preserved at the museum and is operable. The
Huntsville and Madison County Railroad Authority in Huntsville, AL, operates one of the last U23B's used in daily freight service, as of April 2020. HMCR 9554 was originally built in late 1974 as L&N 2800. The last U23B built, originally Conrail 2798, and more recently Providence and Worcester 2203, is in regular freight service at the
Naugatuck Railroad in Thomaston, Connecticut. Carmeuse Lime & Stone in Annville, Pennsylvania, owns a EX-Conrail U23B sitting dormant and half scrapped on a siding on the edge of the property. Western Rail Inc in Airway Heights, WA currently has a U23B that is leased out to other railroads. It is numbered NIWX 2204 and is a Northern Illinois and Wisconsin locomotive. RJ Corman operates at least one, Road Number 2300, after acquiring the Lehigh Railway short line in Northeast Pennsylvania. ==References==
