Allegheny Portage Railroad
Construction of the Old Portage Railroad from Hollidaysburg to Johnstown, thirty six miles long, began in 1831 and took three years to complete. It included a tunnel long as well as a viaduct over the Little Conemaugh River upstream from Johnstown. The vertical ascent from Johnstown was . The vertical ascent from Hollidaysburg was . The project was financed by the State of Pennsylvania as a means to compete with the Erie Canal in New York and the Chesapeake and Ohio Canal and Baltimore and Ohio Railroad in Maryland. The work was done largely through private contractors. The railroad utilized eleven grade lines and ten cable inclined planes, five on either side of the summit of the Allegheny Ridge to carry loaded canal boats on flatbed railroad cars. Trains of two-three cars were pulled on grade lines by mules. On incline planes, stationary steam engines pulled up and lowered down cars by hemp ropes switching to wire ropes in 1842.
