Union Railroad (Baltimore)
The Union Tunnel is a railroad tunnel on Amtrak's Northeast Corridor in Baltimore, Maryland adjacent to Pennsylvania Station that was built to connect the Pennsylvania Railroad's original mainline to Philadelphia, Pennsylvania and points north. The tunnel consists of two parallel bores: the original bore from 1873 has a single track, while a newer bore from 1934 has two tracks. Original tunnel The Union Tunnel was originally constructed as part of the Union Railroad and served as the northern and eastern approach to Baltimore Union Station (now called Pennsylvania Station). In all, the Union Railroad was in length, extending from the northern terminus of the Baltimore and Potomac Rail Road to the southern terminus of the Northern Central Railway. The junction with the Baltimore and Potomac lies between Pennsylvania Station and the northern portal of the Baltimore and Potomac Tunnel. The Union Railroad joined the Northern Central at Bayview Junction, Maryland on the northeast s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Amtrak's 25 Hz Traction Power System
Amtrak's 25 Hz traction power system is a Traction power network, traction power grid operated by Amtrak along the southern portion of its Northeast Corridor (NEC): the 226.6 route miles (362 km) between Washington, D.C. and New York City and the 104 route miles (167 km) between Philadelphia and Harrisburg, Pennsylvania. The Pennsylvania Railroad constructed it between 1915 and 1938. Amtrak inherited the system from Penn Central, the successor to the Pennsylvania Railroad, in 1976, along with the Northeast Corridor. This is the reason for using 25 Hz, as opposed to 60 Hz, which is the standard for power transmission in North America. In addition to serving the NEC, the system provides power to NJ Transit Rail Operations (NJT), the SEPTA, Southeastern Pennsylvania Transportation Authority (SEPTA) and the MARC Train, Maryland Area Regional Commuter Train (MARC). Only about half of the system's electrical capacity is used by Amtrak. The remainder is sold to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transportation Buildings And Structures In Baltimore
Transport (in British English), or transportation (in American English), is the intentional movement of humans, animals, and goods from one location to another. Modes of transport include air, land (rail and road), water, cable, pipeline, and space. The field can be divided into infrastructure, vehicles, and operations. Transport enables human trade, which is essential for the development of civilizations. Transport infrastructure consists of both fixed installations, including roads, railways, airways, waterways, canals, and pipelines, and terminals such as airports, railway stations, bus stations, warehouses, trucking terminals, refueling depots (including fueling docks and fuel stations), and seaports. Terminals may be used both for interchange of passengers and cargo and for maintenance. Means of transport are any of the different kinds of transport facilities used to carry people or cargo.

Railroad Tunnels In Maryland
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 Track (rail transport), 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 Railroad tie, sleepers (ties) set in track ballast, 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 friction, frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The rail transport operations, operation is carried out by a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Overhead Line
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, trolleybuses or trams. It is known variously as: * Overhead catenary * Overhead contact system (OCS) * Overhead equipment (OHE) * Overhead line equipment (OLE or OHLE) * Overhead lines (OHL) * Overhead wiring (OHW) * Traction wire * Trolley wire This article follows the International Union of Railways in using the generic term ''overhead line''. An overhead line consists of one or more wires (or rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regular intervals. The feeder stations are usually fed from a high-voltage electrical grid. Overview Electric trains that collect their current from overhead lines use a device such as a pantograph, bow collector or trolley pole. It presses against the underside of the lowest overhead wire, the contact wire. Current collectors ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Northeast Corridor
The Northeast Corridor (NEC) is an electrified railroad line in the Northeast megalopolis of the United States. Owned primarily by Amtrak, it runs from Boston through Providence, New Haven, Stamford, New York City, Philadelphia, Wilmington, and Baltimore to Washington, D.C.
