Allegheny Portage Railroad, Historic railroad line in Blair County, United States.
The Allegheny Portage Railroad stretches across 36 miles through the Allegheny Mountains, connecting Hollidaysburg and Johnstown with ten inclined planes and level tracks.
Constructed between 1831 and 1834, this railroad was part of the Main Line of Public Works, reducing travel time from Philadelphia to Pittsburgh from weeks to days.
The railroad transformed Pennsylvania's transportation landscape by enabling merchants, travelers, and soldiers to efficiently cross the Allegheny Mountains for commerce and exploration.
Visitors can explore the Summit Level Visitor Center, which provides exhibits, films, and guided tours explaining the railroad's mechanical operations and historical significance.
The Staple Bend Tunnel, constructed as part of this railroad system, holds the distinction of being the first railroad tunnel built in the United States.
