Was the Edison Sault Power Canal built after the Allegheny Portage Railroad discontinued operating?
Allegheny Portage Railroad The Allegheny Portage Railroad was the first railroad constructed through the Allegheny Mountains in central Pennsylvania, United States; it operated from 1834 to 1854 as the first transportation infrastructure through the gaps of the Allegheny that connected the midwest to the eastern seaboard across the barrier range of the Allegheny Front. Authorized as part of the Main Line of Public Works legislation in 1824, it was a series of ten inclines connecting to a branch of the Pennsylvania Canal at either end, approximately 36 mi long overall. It had five inclines on either side of the drainage divide running athwart the ridge line from Blair Gap through along the kinked saddle at the summit into Cresson, Pennsylvania. The Portage Railroad utilized cleverly designed wheeled barges to ride a narrow-gauge rail track with steam-powered stationary engines lifting the vehicles. Except for peak moments of severe storms, it was an all-weather, all-seasons operation. Along with the rest of the Main Works, it cut transport time from Philadelphia to the Ohio River from weeks to just 3–5 days. The roadbed of the railroad did not incline monotonically upwards, but rose in relatively long, saw-toothed stretches of slightly-sloped flat terrain suitable to animal powered towing, alternating with steep cable railway inclined planes using static steam engine powered windlasses, similar to mechanisms of modern ski lifts.
Genesee Valley Canal Railroad The Genesee Valley Canal Railroad was a part of the Pennsylvania Railroad system in central New York. It was built on the former Genesee Valley Canal alignment.
