The Bessemer & Lake Erie was one of the last Class I roads to have F units in active service. The aging EMD’s were mainly assigned to two regions. Moving ore cars around the Lake Erie ore docks at Conneaut, Ohio, under the banner of fellow US Steel subsidiary Pittsburgh & Conneaut Dock Company, was where the majority of B&LE’s remaining F units congregated. B&LE’s Western Allegheny branch, a 21 mile extension from the main line at Queen Junction into Pennsylvania’s bituminous coal fields, was the exclusive domain of F units , as its trackage could not accommodate the six-wheel trucks of the B&LE SD fleet. Here a good representation the cab unit fleet is depicted at the Western Allegheny engine facility at Kaylor. There are two B&LE A units, a freshly-painted B unit, and an A unit painted in the Pittsburg & Conneaut Dock yellow scheme.
