C&O Diesel Roster: All-Time

Published: October 3, 2023

By: Adam Burns

The Chesapeake & Ohio operated diesels from nearly every major builder including Electro-Motive, Alco, General Electric, and even a few models from Baldwin.  Interestingly, the railroad never purchased any Fairbanks-Morse products.

The C&O's first-generation road power primarily consisted of EMD products while second-generation products included both EMD and General Electric.  The railroad's final new units included a group of SD50s acquired in 1984/1985.

The information presented here provides a complete, all-time Chesapeake & Ohio diesel roster.  The railroad was late to the diesel era thanks to its strong commitment to steam technology as a result of its considerable coal business.
