The Allegheny Portage Railroad traversed the Allegheny Mountains between Hollidaysburg and Johnstown, Pennsylvania, connecting the Eastern and Western Divisions of the Pennsylvania Main Line Canal. The mountains represented a formidable obstacle in early transportation routes. The inclines and planes of the Allegheny Portage Railroad provided a unique engineering solution for transporting the canal boats across the mountains.
