This article is about a railroad line. For the agglomeration of metropolitan areas, see BosWash.

The Northeast Corridor (NEC) is an electrified rail line in the Northeast U.S. with overhead wires running from Washington, DC to Boston, Massachusetts, passing through Baltimore, Maryland, Philadelphia, Pennsylvania, New York, New York, New Haven, Connecticut and Providence, Rhode Island. Mostly operated and owned by Amtrak, the NEC offers the only true high-speed rail service in the United States (Amtrak's Acela Express). Several commuter rail agencies - MARC, SEPTA, NJ Transit, Metro-North, Shore Line East and MBTA - provide local service along the Northeast Corridor, some electrified and some diesel.

Current passenger services

As of mid-December 2004, 55 round-trip Amtrak trains use the busiest part of the Corridor, between New York and Philadelphia, every weekday, with an extra one on Wednesday and Friday (Cardinal). 349 round trips use this part per week.

The following Amtrak services run along the Northeast Corridor:

• Acela Express - high-speed rail from Boston to Washington
• Regional - umbrella term for most local service along the NEC, continuing to Newport News, Virginia and with a branch to Springfield, Massachusetts
• Metroliner - New York to Washington
• Keystone - umbrella term for local service along the Keystone Corridor, using the NEC from New York to Philadelphia and continuing to Harrisburg, Pennsylvania

Other services - the Cardinal to Chicago, Illinois, Carolinian to Charlotte, North Carolina, Crescent to New Orleans, Louisiana, Lake Shore Limited to Chicago, Illinois, Palmetto to Savannah, Georgia, Pennsylvanian to Pittsburgh, Pennsylvania, Silver Meteor and Silver Star to Miami, Florida, and Vermonter to St. Albans, Vermont - also run along parts of the NEC.

Non-Amtrak commuter rail services

In addition to Amtrak, several commuter rail agencies operate passenger service using the Northeast Corridor tracks.

• MARC Penn Line - Washington to Perryville, Maryland
• SEPTA R2 Newark from Newark, Delaware to Philadelphia
• SEPTA R7 Trenton from Philadelphia to Trenton, New Jersey
• New Jersey Transit Northeast Corridor Line from Trenton to New York
• Metro-North Railroad New Haven Line from New Rochelle, New York to New Haven, Connecticut
• Shore Line East from Stamford, Connecticut to New London, Connecticut
• MBTA Attleboro/Stoughton Line from Providence, Rhode Island to Boston

Ownership

Track

With primarily passenger services, the Northeast Corridor is a cooperative venture between Amtrak and various state agencies. Amtrak currently owns the Northeast Corridor between Washington and New Rochelle, New York. The segment of the NEC between New Rochelle, New York and New Haven, Connecticut is owned by the States of New York and Connecticut and operated by the Metro-North Railroad. Amtrak also owns the section between New Haven, Connecticut and the Rhode Island-Massachusetts state line, and operates the section to Boston, owned by the State of Massachusetts and originally operated by the Massachusetts Bay Transportation Authority.

Stations

Amtrak owns Pennsylvania Station in New York, 30th Street Station in Philadelphia, and Union Station in Washington.

Freight service

Freight service is provided on the Northeast Corridor by trackage rights. The Norfolk Southern Railway operates over the line south of Philadelphia, and CSX Transportation has rights from New York to New Haven and in Massachusetts. Between Philadelphia and New York, Conrail, which formerly provided service on the whole line, still operates over the line, as a local switching and terminal company for both CSX and Norfolk Southern. The Providence and Worcester Railroad operates local freight service from New Haven into Rhode Island and has overhead trackage rights from New Haven to New York.

History

Unlike most European high-speed rail lines, built on new rights-of-way, the NEC uses existing lines built as early as the 1830s; the most recent section, the Hell Gate Bridge and New York Connecting Railroad in New York, opened in 1917. From 1893, when the NYNH&H acquired the Old Colony Railroad, including the Providence-Boston section of the NEC, the NEC has been owned by two companies - the Pennsylvania Railroad (PRR) from Washington to New York and the New York, New Haven and Hartford Railroad (NYNH&H) from New York to Boston. Under the PRR and NYNH&H, the lines were known as the Philadelphia-to-Washington Main Line, Philadelphia-to-New York Main Line and Shore Line.

In 1968 the PRR merged with its former rival, the New York Central Railroad, to form Penn Central Transportation. The NYNH&H was merged into Penn Central in 1969, bringing the whole Washington-Boston corridor under control of one company. With the 1971 formation of Amtrak, the intercity passenger services were under government control. In 1976 the bankrupt Penn Central was taken over by the government corporation Conrail, and the sections of line that had not already been sold to commuter transportation authorities were sold to Amtrak.

New York electrification

The electrification projects of the steam railroads in the area which is now the NEC began with the Park Avenue Tunnel of the New York and Harlem Railroad, part of the New York Central and Hudson River Railroad (NYC) to its Grand Central Station in New York, and also used by the NYNH&H via trackage rights. With the 1900 opening of the Gare d'Orsay, the first electrified urban rail terminal in the world, a new technology was available, and the NYC began planning for electrification between Grand Central and the split at Mott Haven. Electricity was already in use on various branch lines of the NYNH&H, but was provided by interurban streetcars via third rail or trolley wire.

Low visibility caused by the steam locomotives used at the time caused an accident killing 17 on January 8, 1902, and the resulting public outcry led to a push for electric operation in Manhattan. In 1905 the NYNH&H announced that it would electrify its main line from New York to Stamford, Connecticut. Along with the construction of the new Grand Central Terminal, opened in 1912, the NYC electrified its lines, beginning on December 11, 1906 with suburban multiple unit service to High Bridge on the Hudson Line. Electric locomotives began serving Grand Central February 13, 1907, and all NYC passenger service into Grand Central was electrified July 1. NYNH&H electrification began July 24 to New Rochelle, August 5 to Port Chester and October 6, 1907 the rest of the way to Stamford. Steam trains last operated into Grand Central on June 30, 1908, after which all NYNH&H passenger trains into Manhattan were electrified. On June 22, 1914 the NYNH&H electrification was extended to New Haven, where it would end for many years.

At the same time, the PRR was building its Pennsylvania Station and electrified approaches, served by the PRR's lines in New Jersey and the Long Island Rail Road (LIRR). LIRR electric service began in 1905 on the Atlantic Avenue Line from downtown Brooklyn past Jamaica, and in June 1910 on the branch to Long Island City, part of the main line to Penn Station. Penn Station opened September 8, 1910 for LIRR trains and November 27 for the PRR, which changed engines and had platforms for transferring at Manhattan Transfer.

On July 29, 1911 the NYNH&H began electric service on its Harlem River Branch, a suburban branch that would become a main line with the completion of the New York Connecting Railroad and its Hell Gate Bridge. The bridge opened on April 1, 1917, but was operated by steam with an engine change at Sunnyside Yard east of Penn Station until 1918.

Philadelphia electrification

In 1905 the PRR announced that it would electrify its suburban lines at Philadelphia, eventually extending it all the way between New York and Washington. Electric service began September 11, 1915 with multiple unit trains west to Paoli on the PRR main line (now the Keystone Corridor). Electric service to Chestnut Hill (now the R8 Chestnut Hill West), including a stretch of the NEC, began March 30, 1918. Local electric service to Wilmington, Delaware on the NEC began September 30, 1928, and the other way to Trenton, New Jersey on June 29, 1930.

NEC southern section: New York to Washington

PRR electric service began between Exchange Place, the Jersey City terminal, and New Brunswick, New Jersey on December 8, 1932, including the extension of Penn Station electric service from Manhattan Transfer. On January 16, 1933 the rest of the electrifcation, between New Brunswick and Trenton, opened, giving a fully electrified intercity line between New York and Philadelphia, and beyond to Wilmington. Through trains to Washington began running under electricity to Wilmington February 12, with the engine change moved from Manhattan Transfer to Wilmington. The same was done on April 9 for trains running west from Philadelphia, with the change point moved to Paoli.

In 1933 the electrification south of Wilmington stalled due to the Great Depression, but the PRR managed to get a loan from the federal government, and resumed work the next year. The tunnels at Baltimore were rebuilt, and electric revenue service between New York and Washington began February 10, 1935. On April 7 the electrification of all New York-Washington passenger trains was complete, with 639 daily trains, 191 locomotive-hauled and the other 448 multiple unit. New York-Washington electric freight service began May 20 with the electrification of freight lines in New Jersey and Washington. Extensions to Potomac Yard across the Potomac River from Washington, as well as several freight branches along the way, were electrified in 1937 and 1938. The Potomac Yard electrifcation remained until 1981.

NEC northern section: New York to Boston

Electrification of the portion north of New Haven to Providence and Boston was planned by the NYNH&H, but financial problems delayed the work until modern times.

Penn Central and Amtrak: forming the NEC

Despite the New York Connecting Railroad and Hell Gate Bridge joining the two segments, they were operated almost entirely independently of each other until the merger of the PRR and NYNH&H into Penn Central Transportation in 1968 and 1969 respectively, and the establishment of Amtrak in 1971. On September 21, 1970 all New York-Boston trains but the Turboservice were rerouted into Penn Station from Grand Central, and the Turboservice was moved February 1, 1971. Amtrak, which took over intercity service on May 1, 1971, soon began running more trains through New York, partly due to poor maintenance at Sunnyside Yard.^[1]

At the same time, rail freight service in New England was declining. The February 26, 1975 Preliminary System Plan for Conrail proposed abandoning all freight on the Shore Line (NEC) between Groton, Connecticut and Hills Grove, Rhode Island. However, on March 14, the U.S. Railway Association announced that it had reevaluated the line segment and would be keeping it in operation.^[2]

The State of New York bought and the State of Connecticut leased their sections of the New Haven Line, between Woodlawn, New York and New Haven, Connecticut, from Penn Central on January 1, 1971; the Metropolitan Transportation Authority operated the line. On January 27, 1973 the State of Massachusetts bought the Attleboro/Stoughton Line in Massachusetts for the Massachusetts Bay Transportation Authority.^  The Regional Rail Reorganization Act of 1973 provided for Amtrak to purchase the NEC, and all other NEC trackage passed to Amtrak on April 1, 1976 with the formation of Conrail, with Conrail trackage rights on the full line. Except between New Haven and the Rhode Island/Massachusetts line, which were sold to the Providence and Worcester Railroad, those rights remained until the 1999 breakup of Conrail, when they were split between the Norfolk Southern Railway to the south and CSX Transportation to the north. Amtrak now operates and maintains the portion in Massachusetts, but the line from New Haven to New Rochelle, New York is operated by the Metro-North Railroad; this has been a problem with establishment of high-speed service.

Preparing for Acela Express

In preparation for the new higher-speed Acela Express trains, Amtrak substantially upgraded the portion of the Northeast Corridor north of New York in the early 1990s. Grade crossings were eliminated, some bridges were rebuilt, and curves were modified. Beginning in 1996, the electrification was extended north along the 157-mile (253 km) section of track between New Haven and Boston. Wooden crossties were replaced with those made of concrete and heavier welded rail (replacing the segmented rail) was laid down. Train platforms south of New York, originally constructed for the Metroliner multiple-unit cars of the late 1960's, were rebuilt to accommodate the new cars. Platforms north of New York had to be constructed completely from scratch.

Grade crossings

Due to the high-speed nature of Acela Express service, which uses the whole line, grade crossings are highly discouraged, and most have been eliminated, mostly started after 1976 south of New York City (when Amtrak replaced the Metroliner m.u. cars with the locomotive-hauled Metroliners). The remaining ones use preventative measures such as four-quadrant gates, except in New London, Connecticut, whose three crossings are very close to the station.

The following 11 crossings remain, all in southeastern Connecticut:

• Stonington, Connecticut
  • Palmer Street
  • Freeman's Crossing
