Railroad Electrification In The United States
Railroad electrification in the United States began at the turn of the 20th century and comprised many different systems in many different geographical areas, few of which were connected. Despite this situation, these systems shared a small number of common reasons for electrification. Most of the systems discussed in this article are either no longer electrified, or are now part of the Northeast Corridor and Keystone Corridor systems used by Amtrak and several commuter rail lines. A few isolated systems operate exclusively for hauling coal from mines to power plants. Most mass transit, streetcar, and interurban systems electrified very early (many from the beginning) but are not within the scope of this article. Impetus for electrification Laws banning steam locomotives (smoke abatement) A number of municipalities passed laws in the early part of the 20th century forbidding steam locomotives from operating within city limits, after some bad accidents caused by the awful conditi ...

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. The NEC closely parallels Interstate 95 for most of its length, and is the busiest passenger rail line in the United States both by ridership and by service frequency as of 2013. The NEC carries more than 2,200 trains daily. The corridor is used by many Amtrak trains, including the high-speed Acela, intercity trains and several long-distance trains. Most of the corridor also has frequent commuter rail service, operated by the MBTA, Shore Line East, Hartford Line, Metro-North Railroad, Long Island Rail Road, New Jersey Transit, SEPTA and MARC. While large through freights have not run on the NEC since the early 1980s, several companies continue to run smaller local freights over some select few sec ...

Philadelphia To Harrisburg Main Line
The Philadelphia to Harrisburg Main Line is a rail line owned and operated by Amtrak in the U.S. state of Pennsylvania. This is the only electrified Amtrak line in the United States outside of the main line of the Northeast Corridor. The line runs from Philadelphia, PA, Philadelphia, where it meets the Northeast Corridor at Zoo interlocking (railway milepost, milepost 1.9), west to Harrisburg, PA, Harrisburg (MP 104.6), where electrification ends. It is part of the longer Keystone Corridor, which continues west to Pittsburgh, PA, Pittsburgh along the Norfolk Southern Railway's Pittsburgh Line.Federal Railway Administration, This section is sometimes referred to as "Keystone East" and is part of Amtrak's Keystone Service. Philadelphia's Suburban Station was the original start of the line – as well as the headquarters for the Pennsylvania Railroad – and is milepost zero for the line. However, current service patterns dictate that all passenger rail service on the line b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Penn Line
The Penn Line is a MARC commuter rail service running from Union Station in Washington, D.C., to Perryville, Maryland, along the far southern leg of the Northeast Corridor. However, the great majority of trains terminate at Baltimore's Penn Station. It is MARC's busiest and only electric line. With trains running at speeds of up to , it is the fastest commuter line in the United States. The service is operated by Amtrak under contract to the Maryland Transit Administration. MARC sets the schedules, owns most of the stations, and controls fares, while Amtrak owns and maintains the right-of-way, supplies employees to operate trains, and maintains the rolling stock. It is by far the busiest of MARC's three lines, with twice as many trains and twice as many passengers as the Brunswick and Camden lines combined. The Penn Line is the successor to commuter services between Washington and Baltimore provided by the Pennsylvania Railroad (PRR), Penn Central, and Conrail dating back ...

MARC Train
MARC (Maryland Area Rail Commuter) is a commuter rail system in the Baltimore–Washington metropolitan area. MARC is administered by the Maryland Transit Administration (MTA) and operated under contract by Alstom and Amtrak on track owned by CSX Transportation (CSXT) and Amtrak. In , the system had a ridership of , or about per weekday as of , much less then the pre-pandemic daily ridership of 40,000 per weekday. With trains reaching speeds of , MARC has the highest top speed of any commuter railroad in the United States. Operations MARC has three lines that radiate from Union Station in Washington, D.C.: the Brunswick Line (18 weekday trains), the Camden Line (21 weekday trains), and the Penn Line (58 weekday trains). The Penn Line is the only line with weekend service, having 18 trains on Saturdays and 12 on Sundays. Service is reduced or suspended on certain Federal holidays. All MARC trains operate in push-pull mode. The cab car is typically on the end of the train ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pennsylvania Station (New York City)
Pennsylvania Station, also known as New York Penn Station or simply Penn Station, is the main intercity railroad station in New York City and the busiest transportation facility in the Western Hemisphere, serving more than 600,000 passengers per weekday . It is located in Midtown Manhattan, beneath Madison Square Garden in the block bounded by Seventh and Eighth Avenues and 31st and 33rd Streets, and in the James A. Farley Building, with additional exits to nearby streets. It is close to Herald Square, the Empire State Building, Koreatown, and Macy's Herald Square. Penn Station has 21 tracks fed by seven tunnels (the two North River Tunnels, the four East River Tunnels, and the single Empire Connection tunnel).

Intercity trains are operated by Amtrak, which owns the station, while commuter rail services are ope ... [...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] |
Shore Line East

Amtrak's 60 Hz Traction Power System
Amtrak operates a 60 Hz traction power system along the Northeast Corridor between New Haven, Connecticut,Specifically, Amtrak's 25 kV system begins at the Mill River Interlocking about two miles north of New Haven Union Station and Boston, Massachusetts. This system was built in the late 1990s and supplies locomotives with power from an overhead catenary system at 25 kV alternating current with a frequency of 60 Hz. The system is also commonly known as the ''Northend Electrification'', in contrast to the '' Southend Electrification'' that runs between New York City and Washington, D.C. History In 1992, Congress passed the ''Amtrak Authorization and Development Act'' requiring Amtrak to establish high-speed rail passenger service between New York City and Boston. The goal was to reduce travel time in this corridor from 4.5 hours to less than 3 hours. Revenue from this service was expected to play a critical role in helping Amtrak achieve operating self-sufficienc ... [...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 colle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
