Here's an interesting article on the Beech Creek Railroad in Clearfield County, specifically near Gorton, Grassflat and the ghost town of Peale in Cooper Township. The Beech Creek Railroad came up the Allegeny Front from Jersey Shore along Beech Creek, then across the mountain top from Clarence to the Moshannon Creek near Snow Shoe. The little towns through the area sprang up around mine shafts that provided the rail traffic. Most of these towns are gone now, and the railroad in the area is now a walking and four-wheeler trail.
