At the summit of the historic Allegheny Portage Railroad, trains first crossed the Allegheny Mountains in 1834. The railroad ceased operations in 1854, but remnants of historic structures remain visible, including Incline No. 6, the foundations of Engine House No. 6, a relatively level stretch of track between Inclines 5 and 6, and the Lemon House, a mountaintop tavern built in 1832 by Samuel Lemon where thousands of railroad passengers refreshed themselves. One of ten inclined planes on the railroad carried railroad cars and canal boats up and down the steep slopes, while on the summit level railroad cars were pulled by horses or locomotives.
