The Emmitsburg Railroad was initially built in the 1870s, from a wye called Emmitsburg Junction near Rocky Ridge, MD, where it connected to the Western Maryland. This short line headed north through Motters, and terminated in Emmitsburg.
The line traveled through rolling farmland, and was likely put out of business as roads in the area were improved.
Small sections of the right of way can be located, but the route is not a trail. The wye at Emmitsburg Junction now passes through a church park (the former WM survives as Maryland Midland); and the right of way near Motters can be seen passing through a wooded area. Other than the bridge pier in the photo below, no trace of the line appears in Emmitsburg itself.
