The Waynesburg and Washington was a narrow gauge line between Washington, Pennsylvania and Waynesburg, Pennsylvania. The line was conceived by John Day in 1874 and chartered in 1875, with construction beginning in August of 1875. It was converted to standard gauge in 1944 and renamed the Waynesburg Secondary. It had steep grades and sharp curves. It had few online industries and was used as an interurban passenger route. It was owned by the Pennsylvania Railroad. It was created on April 4, 1868 and existed until 1976, at which time Conrail declined taking it over. Tracks were removed in 1978.
