Staple Bend Tunnel
East Taylor Township, Cambria County, Pennsylvania
Marker Inscription
First railroad tunnel built in the U.S. and a part of the Portage Railroad. The masonry is intact and a unique engineering feat of the times. Can be visited a few miles east of here, via Mineral Point.
Erected by Pennsylvania Historical and Museum Commission
The Story
The Staple Bend Tunnel, built as part of the Allegheny Portage Railroad, was the first railroad tunnel constructed in the United States. Its finely cut masonry, still intact, was regarded as a remarkable engineering feat in an age when boring through solid rock for a railway was nearly unheard of. Reachable a few miles east via Mineral Point, it endures as a monument to early American ingenuity.
Why it matters
As the nation's first railroad tunnel, Staple Bend marks a pioneering moment in the engineering that would carry American railroads across every mountain barrier.

Canal Basin
Hollidaysburg, PA · est. 1982
At Hollidaysburg, the 127-mile Juniata Division of the Pennsylvania Canal met the Allegheny Portage Railroad, an ingenious system that hauled canal boats over the mountains toward Johnstown, 36 miles west. The canal opened in 1832 and the railroad in 1834, together forming a continuous route across the formidable Allegheny barrier. Engineers marveled at the portage line, which climbed nearly 1,400 feet in just ten miles using inclined planes.
Allegheny Portage Railroad Plane No. 2
Portage Township, PA · est. 1994
Before tunnels pierced the Alleghenies, the mountains stood as a wall across Pennsylvania's ambitious canal system. From 1834 to 1854 the Allegheny Portage Railroad solved the problem with a feat of engineering, hauling entire canal boats up and over the ridge along a series of inclined planes on a 36-mile line between Hollidaysburg and Johnstown. Horses and mules pulled the first cars, later giving way to steam locomotives, with Plane No. 2 serving as the line's headquarters.
Charles M. Schwab
Loretto, PA · est. 1947
Charles M. Schwab rose from humble beginnings in this Cambria County region to become one of the titans of American steel, so gifted that Andrew Carnegie reportedly said he knew more about steel than any man alive. At the height of his fortune Schwab kept a grand estate near Loretto, later given over to St. Francis College. His story tracks the explosive growth of the steel industry that powered America's rise as an industrial giant.
Portage Railroad
Cresson Township, PA · est. 1947
This spot marks the location of Plane No. 5, one of ten inclined planes on the Allegheny Portage Railroad, an ingenious system that hauled canal boats over the mountains by rail between Hollidaysburg and Johnstown. Completed in the 1830s, it closed the last gap in Pennsylvania's Main Line of Public Works, allowing freight and passengers to cross the formidable Allegheny ridge. The road to Lilly still traces the old route over the mountain.
