Allegheny Portage Railroad
http://dbpedia.org/resource/Allegheny_Portage_Railroad an entity of type: Thing
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. Approximately 36 miles (58 km) long overall, both ends connected to the Pennsylvania Canal, and the system was primarily used as a portage railway, hauling river boats and barges over the divide between the Ohio and the Susquehanna Rivers. Today, the remains of the railroad are preserved within the Allegheny Portage Railroad National Historic Site operated by the National Park Service.

De spoorlijn maakte scheepsverkeer over het Alleghenygebergte mogelijk en verbond zo de rivier de Ohio met de Susquehanna. De schuiten werden vervoerd op spoorwagons, getrokken door paarden of (op de steile stukken) op hellende vlakken. Het traject omvatte ook een viaduct en de eerste spoortunnel in de V.S. De Allegheny Portage Railroad bleef in gebruik tot 1857, toen het vervangen werd door een spoorweg over het Alleghenygebergte met stoomlocomotief.

. . . Occasionally the rails were laid upon the extreme verge of a giddy precipice; and looking from the carriage window, the traveler gazes sheer down, without a stone or scrap of fence between, into the mountain depths below . . . It was very pretty travelling thus at a rapid pace along the heights of the mountains in a keen wind, to look down into a valley full of light and softness; catching glimpses, through the treetops, of scattered cabins; . . . men in their shirt sleeves, looking on at their unfinished houses, planning out tomorrow's work; and we riding onward, high above them, like a whirlwind. It was amusing, too, when we had dined, and rattled down a steep pass, having no other moving power than the weight of the carriages themselves, to see the engine, released long after us, come buzzing down alone, like a great insect, its back of green and gold so shining in the sun . . . It stopped short of us . . . when we reached the canal, and, before we left the wharf, went panting up this hill again, with the passengers who had waited our arrival for the means of traversing the road by which we had come.

Approximately 36 miles (58 km) long overall, both ends connected to the Pennsylvania Canal, and the system was primarily used as a portage railway, hauling river boats and barges over the divide between the Ohio and the Susquehanna Rivers. Today, the remains of the railroad are preserved within the Allegheny Portage Railroad National Historic Site operated by the National Park Service. The railroad was authorized as part of the Main Line of Public Works legislation in 1824. 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 endpoints connected to the Canal at Johnstown on the west through the relative flats to Hollidaysburg on the east. The Railroad utilized cleverly designed wheeled barges to ride a narrow-gauge rail track with steam-powered stationary engines lifting the vehicles. 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. 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. Considered a technological marvel in its day, it played a critical role in opening the interior of the United States beyond the Appalachian Mountains to settlement and commerce. It included the first railroad tunnel in the United States, the Staple Bend Tunnel, and its inauguration was marked with great fanfare.

De overblijfselen van de Allegheny Portage Railroad, ongeveer 19 kilometer ten westen van Altoona, zijn sinds 1962 een National Historic Landmark en sinds 1964 een van de National Historic Sites.
