Quemahoning Tunnel
The Quemahoning Tunnel was a tunnel that was constructed for use on the stillborn South Pennsylvania Railroad. The tunnel was located in Somerset County, Pennsylvania near the 106.3 milemarker of the Pennsylvania Turnpike. While the South Pennsylvania Railroad never came to fruition and is known in history as " Vanderbilt's Folly", the Quemahoning Tunnel has the distinction of being the only tunnel of the nine tunnels constructed on the South Pennsylvania alignment that was actually used by railroads, as it was used by the Pittsburgh, Westmoreland and Somerset Railroad from 1909 to 1916. When the newly formed Pennsylvania Turnpike Commission purchased the South Pennsylvania Railroad alignment in 1937, the Turnpike considered using the Quemahoning Tunnel, but instead bypassed it. The Laurel Hill Tunnel, which was also constructed by the railroad but used by the Pennsylvania Turnpike until its own bypassing in 1964, is located six miles to the west.

Pittsburgh, Westmoreland And Somerset Railroad
The Pittsburgh, Westmoreland, & Somerset Railroad (PW&S) was a short-lived railroad that connected the Pennsylvania communities of Ligonier and Somerset, running over a mountain known as Laurel Hill or Laurel Mountain. On occasion the railroad's name was spelled as the ''Pittsburg, Westmoreland, & Somerset'', using the older spelling of Pittsburgh without the ''h''. Although Pittsburgh is in the railroad's name, it never served that city. The word Westmoreland refers to Westmoreland County, where the town of Ligonier is located. The railroad's sole tunnel was the Quemahoning Tunnel, also known as the Lumber Railroad Tunnel, which had originally been built for the South Pennsylvania Railroad but had not been previously used. Although the Pennsylvania Railroad did not control the PW&S, the Pennsylvania Railroad provided construction materials. The Pennsylvania Railroad regarded the PW&S as a feeder which would compete for customers against the Baltimore & Ohio Railroad, which had ...

Tunnel
A tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment. Secret tunnels are built for military purposes, or by civilians for smuggling of weapons, contraband, or people. Special tunnels, such as wildlife crossings, are built to allow wildlife to cross human-made barriers safely. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Pennsylvania Railroad
The South Pennsylvania Railroad is the name given to two proposed, but never completed, Pennsylvania railroads in the nineteenth century. Parts of the right of way for the second South Pennsylvania Railroad were reused for the Pennsylvania Turnpike in 1940. Initial promotions The first South Pennsylvania Railroad was originally chartered as the Duncannon, Landisburg, and Broad Top Railroad Company on May 5, 1854. Its intended route began in Duncannon, passed through Landisburg and Burnt Cabins and ended on the Juniata River via the Broad Top Mountain coalfields. On May 5, 1855, it was renamed the Sherman's Valley and Broad Top Railroad Company, and the planned eastern terminus was changed from Duncannon to the mouth of Fishing Creek, in Perry County near Marysville, in order to connect with the Pennsylvania Railroad. Another amendment to the charter on May 12, 1857, allowed it to connect with the Allegheny Portage Railroad and the Pittsburgh and Connellsville Railroad. Around ...

Pennsylvania Turnpike
The Pennsylvania Turnpike (Penna Turnpike or PA Turnpike) is a toll highway operated by the Pennsylvania Turnpike Commission (PTC) in the U.S. state of Pennsylvania. A controlled-access highway, it runs for across the state. The turnpike's western terminus is at the Ohio state line in Lawrence County, where the road continues west as the Ohio Turnpike. The eastern terminus is at the New Jersey state line at the Delaware River–Turnpike Toll Bridge over the Delaware River in Bucks County, where the road continues east as the Pearl Harbor Memorial Extension of the New Jersey Turnpike. The highway runs east–west through the southern part of the state, connecting the Pittsburgh, Harrisburg, and Philadelphia areas. It crosses the Appalachian Mountains in central Pennsylvania, passing through four tunnels. The turnpike is part of the Interstate Highway System; it is designated as part of Interstate 76 (I-76) between the Ohio state line and Valley Forge, I-70 (concurrent w ...

Pennsylvania Turnpike Commission
The Pennsylvania Turnpike Commission (PTC) is an agency created in 1937 to construct, finance, operate, and maintain the Pennsylvania Turnpike (both the mainline and the Northeast Extension). The commission consists of five members. Four members are appointed by the Governor of Pennsylvania, while the fifth member is the Pennsylvania Secretary of Transportation. In addition to the Pennsylvania Turnpike, the commission also operates the James E. Ross Highway, Amos K. Hutchinson Bypass, Mon/Fayette Expressway, and Pittsburgh's Southern Beltway, the latter two of which are currently under construction. The PTC is the only transportation agency in Pennsylvania that is not part of PennDOT, though it does coordinate with PennDOT on road design procedures and guidelines. , Mark Compton is the CEO. History 1930–1970 The PTC was established by law on May 21, 1937, when Pennsylvania Governor George Earle signed Act 211 into law. The first commissioners were named on June 4 of ...

Laurel Hill Tunnel
Laurel Hill Tunnel is a tunnel on the Pennsylvania Turnpike that was bypassed and abandoned in 1964. It is bored through Laurel Ridge, spanning the border of Westmoreland and Somerset counties. Its western portal may be seen from the eastbound side of the Turnpike at milepost 99.3. The tunnel was built for the never-completed South Pennsylvania Railroad, as were two other tunnels to its east—Sideling Hill and Rays Hill—that were similarly on the original Turnpike and abandoned after being bypassed. Bypass The tunnels on the Turnpike had been bottlenecks ever since the Turnpike's opening in 1940 due to reduced speeds and two-way traffic in a single tube. A second tube was added to four tunnels— Allegheny Mountain, Tuscarora Mountain, Kittatinny Mountain, and Blue Mountain—where it was the less expensive option. Unlike the Sideling Hill and Rays Hill tunnels, the Laurel Hill Tunnel is not on the bypassed section commonly known as the Abandoned Pennsylvania Tu ...

Daylighting (tunnels)
Daylighting a tunnel is to remove its "roof" of overlying rock and soil, exposing the railway or roadway to daylight and converting it to a railway or roadway cut. Tunnels are often daylighted to improve vertical or horizontal clearances—for example, to accommodate double-stack container trains or electrifying rail lines, where increasing the size of the tunnel bore is impractical. List of daylighted tunnels * New Zealand ** The railway line through the Manawatu Gorge, when constructed in 1891, had five tunnels. Three of these were daylighted in 2008 to allow for the carriage of large containers (the other two tunnels had their floors lowered). * United Kingdom ** Liverpool Lime Street station was originally approached through a twin-track tunnel completed in 1836. The tunnel was daylighted in the 1880s, and replaced with a deep four-track cutting, with only the eastern approaching Edge Hill railway station remaining as a tunnel. * United States of America ** Auburn Tunnel ...

Railroad Tunnels In Pennsylvania
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer facil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
