GE B23-7: Locomotive Roster
Conrail Cyclopedia Quality!

CR B23-7 The B23-7 was a turbocharged 2,250hp locomotive with a twelve-cylinder 12-7FDL prime mover that rode on four AAR Type-B trucks. It was designed to directly compete with EMD's GP-38-2, which was the most reliable and versatile locomotives of all time and could be found in yard, branchline, and even mainline service. The B23-7 was equally versatile but not as reliable. Still, Conrail purchased 141 of the units between 1977 and 1979, with 117 staying on roster until the final days of the railroad.

The roster below covers those units operated by Conrail from the arrivial of the first unit until May 1999.
