Perkasie Tunnel
The Perkasie Tunnel is a train tunnel located behind the Post Office in Perkasie, Pennsylvania on 7th Street, on a line owned by SEPTA and operated by the East Penn Railroad. The tunnel itself is located near 8th Street and Ridge Road. Northbound passenger trains going through the tunnel traveled to Union Station in Bethlehem and points beyond.

Larimer Township is a township in Somerset County, Pennsylvania, United States. The population was 543 at the 2020 census. It is part of the Johnstown, Pennsylvania, Metropolitan Statistical Area. Larimer Township was named for General William Larimer, Jr., president of the Pittsburgh & Connellsville Railroad. History Brigadier General John Forbes's Expedition of 1758 passed through the area that became Larimer Township, near Will's Creek, as they hacked Forbes Road out of the western Pennsylvania wilderness.

Negro Mountain
Negro Mountain is a long ridge of the Allegheny Mountains in the eastern United States, stretching from Deep Creek Lake in Maryland north to the Casselman River in Pennsylvania. The summit, Mount Davis, is the highest point (3,213 feet) in Pennsylvania. Negro Mountain is flanked by Laurel Hill to the west and Allegheny Mountain to the east.

The mountain retains its elevation above for much of its length, especially in Pennsylvania. The Negro Mountain Tunnel, built for the South Pennsylvania Railroad, is abandoned and was never used. The Mount Davis Natural Area on the Mountain is located within the Forbes State Forest and many trails take hikers throughout this alpine landscape. Weather on the mountain is fierce, frost can occur at any time of the winter and winds and snowstorms are common. Near the summit in Pennsylvania, the tre ...
