Hunter's Run and Slate Belt Railroad
The Hunter's Run and Slate Belt Railroad was a railway line from the Hunter's Run junction of the Gettysburg and Harrisburg Railway that ran southwestward along the south side of Mountain Creek to the Pine Grove Iron Works. The line serviced facilities for mining (e.g., Henry Clay iron mine), for manufacturing (Crane's Siding clay refining plant), and for recreation (Pine Grove Park for excursions). Portions of the railbed are a section of the Appalachian Trail as well as the majority of the Cumberland County Biker/Hiker Trail and the entire  Old Railroad Bed Road that is the southeast border of Pine Grove Furnace State Park.
