In 1920, the Hocking Valley Railroad received 16 freight locomotives from the Lehigh Valley with a 2-10-2 wheel arrangement, which, with a driver diameter of 63 inches, were too slow for their requirements. The new operator gave the almost new locomotives the class designation F-1. A few years later, six went to the Pere Marquette. The Hocking Valley was taken over by the Chesapeake & Ohio in 1930 and those ten remaining locomotives became the class B-1, carried by two Forneys until 1913. They got bigger tenders in 1940 and were used until 1952.
