Allegheny Portage Railroad National Historical Site Commemorates a Great Achievement in Early Transportation
The Allegheny Portage Railroad National Historical Site is located in southwestern Pennsylvania about 12 miles west of Altoona. Authorized on August 31, 1964, this park commemorates an ingenious inclined plane system that provided a vital trans-mountain link in the 400-mile long trade route connecting Philadelphia with the Ohio River Valley during the mid-1800s.
