Pittsburgh Light Rail
The Pittsburgh Light Rail (commonly known as The T) is a light rail system in Pittsburgh, Pennsylvania, and surrounding suburbs. It operates as a deep-level subway in Downtown Pittsburgh, but runs mostly at-grade in the suburbs south of the city.

Panhandle Bridge
The Panhandle Bridge (officially the Monongahela River Bridge) carries two rail lines of the Port Authority "T" line across the Monongahela River in Pittsburgh, Pennsylvania.

The bridge's function was to carry Panhandle Route passenger, mail and express trains from Pennsylvania Station in Pittsburgh, with a tunnel in between the station and the bridge. Pennsy Panhandle freight trains utilized the Ohio Connecting Bridge slightly downstream on the Ohio River, or went the long way around the West Virginia Panhandle via Conway, Pennsylvania.

Penn Central Transportation Company
The Penn Central Transportation Company, commonly abbreviated to Penn Central, was an American class I railroad that operated from 1968 to 1976. Penn Central combined three traditional corporate rivals (the Pennsylvania, New York Central and the New York, New Haven and Hartford railroads), all united by heavy service into the New York metropolitan area and (to a lesser extent) New England and Chicago. The new company failed barely two years after formation, the largest bankruptcy in U.S. history at the time. The Penn Central's railroad assets were nationalized into Conrail along with the other bankrupt northeastern roads; its real estate and insurance holdings successfully reorganized into American Premier Underwriters. History Pre-merger The Penn Central railroad system developed in response to challenges facing northeastern American railroads during the late 1960s. While railroads elsewhere in North America drew revenues from long-distance shipments of commodities suc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

In the case of an easement, it may revert to its original owners if the facility is abandoned. This American English term is also used to denote the land itself. A right of way is granted or reserved over the land for transportation purposes, usually for private access to private land and, historically for a highway, public footpath, rail transport, canal, as well as electrical transmission lines, oil and gas pipelines.Henry Campbell Black: ''Right-of-way.''

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] |
