Railroad yard at Quinnimont, West Virginia, in May 1975. A member of the yard crew is coming out of the yard office at QN Cabin, the building at right, while the two resident yard dogs, one with three legs, stand on the platform. Quinnimont Yard was a busy junction on the Chesapeake & Ohio Railway, serving the coalfields of southern West Virginia. The yard dispatched mine shifters (local trains) to a web of branchlines on both sides of the New River. The shifters traded empty coal cars for loaded ones at several mines, then returned to Quinnimont, where they were assembled into long, mainline trains. Coal railroading changed significantly in the years that followed. With the advent of flood-loading coal mines and unit trains, which run directly from a single mine to their destination, most small coal mines closed and the mine shifters that served them no longer run.
