Operated from 1834 to 1854, the Allegheny Portage Railroad was the first railroad constructed through the Allegheny Mountains in central Pennsylvania. It included the first railroad tunnel in the United States, the Staple Bend Tunnel. Considered a technological marvel in its day, the railroad played a critical role in opening the interior of the United States beyond the Appalachian Mountains to settlement and commerce.
Today, the remains of the railroad are preserved within the Allegheny Portage Railroad National Historic Site operated by the National Park Service.
Among the park's facilities is a former tavern called the Lemon House that was a popular stop for railroad passengers and is now a museum. The Staple Bend Tunnel is preserved in a separate unit. Visitors can also enjoy a picnic area and hiking trails as well as a beautiful cut stone arch bridge.
