Allegheny Portage Railroad National Historic Site

Allegheny Portage Railroad National Historic Site

The Allegheny Portage Railroad was the first railroad constructed over the Allegheny Mountains.This inclined plane railroad operated between 1834-1854 and was considered a technological wonder in its day and played a critical role in opening the interior of the United States to trade and settlement. Allegheny Portage Railroad National Historic Site is located in southwestern Pennsylvania approximately 12 miles west of Altoona. The story of the Allegheny Portage Railroad is one of man overcoming mother nature.

The main unit contains the Summit Level Visitor Center, the historic Lemon House, Engine House #6 Exhibit Shelter, the Skew Arch Bridge, picnic area and hiking trails. The Staple Bend Tunnel unit is located approximately 4 miles east of Johnstown, PA.

While the park is open yearround, the summer is the best time to visit if you wish to catch a Ranger program, hike, van tour, and/or even a concert. The park features hands-on demonstrations in the summer for children to help with. Children can also participate in the Junior Ranger program here!

The first railroad to circumvent the Allegheny Mountains, the Allegheny Portage Railroad was the finishing piece of the Pennsylvania Mainline Canal.  "The Portage," opened in 1834, marking the first time that there was one, direct route between Philadelphia and Pittsburgh.  All things to all people, it served merchants, passengers, slaves in pursuit of freedom, and soldiers from the Mexican War.

When the Portage Railroad opened on March 18, 1834, it was a single track line. The rule was when 2 drivers met the one who had passed the center post had the right to go on. The other driver had to back up. Some sat nose to nose until a magistrate determined who got to the center first.

In 1834, a passenger on the Portage wrote that the engine houses appeared "like fairy castles seated on the tops of lofty hills, and shaded and surrounded by towering oaks and hemlocks". Today, a new generation of hemlock, Pennsylvania's state tree, survives in Allegheny Portage Railroad NHS.

In 1843 cars of bacon and whiskey, left overnight in the tunnel, caught fire from a locomotive spark and the whiskey exploded. Staple Bend Tunnel was closed for a couple of days for repair.

The Conemaugh Viaduct was used by trains even after the Portage Railroad closed. The Johnstown Flood of 1889 washed the original viaduct away, but a replacement was completed within 3 days of the flood.
