Allegheny Portage Railroad National Historic Site in Cambria County, Pennsylvania — The American Northeast (Mid-Atlantic)
Inclined Plane No. 6
In front of you is the site of Inclined Plane No. 6, one of ten inclines on the Allegheny Portage Railroad. The track visible today has been reconstructed.
From 1834 to 1854, railroad cars bearing canal boats, freight, and passengers were pulled up and lowered down this slope by a continuous rope driven by steam engines located in an engine house to your right. The rope ran between the rails, supported by idler pulleys every 24 feet. Whenever possible, ascending cars were counterbalanced with descending cars.
In an open shed at the foot of the incline, a "hitcher" connected westbound cars to the main rope with a short rope. Up here at the engine house, another hitcher disconnected them for the continuing journey by horses or locomotives along the Summit Level.
