The Allegheny Portage Railroad has many interesting things to see. Visit the Lemon House- a historic tavern built to accommodate travelers. Discover the Engine House- a replica of the many buildings that made up the Portage Railroad. Watch a movie in our visitor center and browse the many exhibits and models. Drive out to the Staple Bend Tunnel unit to hike and explore the nine hundred foot tunnel (remember you need to walk 2 miles each direction when visiting the tunnel).
