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

History

The Northeast Corridor (NEC) is most notably defined today by its railway electrification system and its primary mission of facilitating passenger rail service. Many portions of today's NEC were first created as portions of small independent railroad lines, much in the same manner as the growth of railroads throughout North America occurred. By the early 20th century, what is now the NEC was controlled and developed primarily by two large railroads, the New Haven, and the Pennsy.

New York Terminal electrification projects

The significant electrification projects of the steam railroads in the area which is now the NEC began with the major terminals in the busy New York City area. The Grand Central Terminal project of the New York Central Railroad (NYC) was the earlier, followed by Pennsylvania Station of its arch rival, the Pennsylvania Railroad. Both terminal electrification projects were very successful. Soon, expansions of electrified territory spread outward from these major projects.

NEC northern section: New York to Boston

The expansion of New York Central's electrified territory went north and west up the Hudson River Valley, an area which is still served by electrification in modern times, but is not part of today's NEC. However, Grand Central Terminal was also served by the New York, New Haven & Hartford Railroad (more often called simply the "New Haven").

The northern section of today's NEC was built by the New Haven to connect Grand Central Terminal in New York to Boston, Massachusetts. The entire main line from New York City to New Haven, Connecticut was being put under catenary by 1914. An electrification of the portion north of New Haven to Providence, Rhode Island and Boston, Massachusetts was also planned, but financial problems delayed the work for over 75 years, until modern times.

NEC southern section: New York to Washington DC

The Pennsylvania Railroad (PRR, often called simply "the Pennsy"), undertook a major electrification project beginning in 1928 to connect New York to Philadelphia. By 1931, the decision had been made to extend the electrification south to Washington, D.C.. The installation of the catenary and wires was completed all the way to Union Station in Washington D.C. in 1935, forming the southern section of today's NEC.

Penn Central and Amtrak: forming the NEC

The northern and southern sections were essentially joined at New York by the line of the New York Connecting Railroad through Queens and across the Hell Gate Bridge. They were operated almost entirely independently of each other until the merger of the PRR and the New Haven into Penn Central Transportation in 1968 and 1969 respectively, and the establishment of Amtrak in 1971.

Amtrak assumed ownership of most of the Northeast Corridor, which accounts for much of its ridership, from the bankrupt Penn Central in 1976. Amtrak's New York City passenger operations were moved from Grand Central Terminal and consolidated at Pennsylvania Station, which it owns.

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 Penn Station 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, Connecticut and Boston, Massachusetts.

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, D.C. and New Rochelle, New York. The segment of the NEC between New Rochelle, New York and New Haven, Connecticut is owned by the Metro North Railroad. Amtrak also owns the section between New Haven, Connecticut and the Rhode Island-Massachusetts state line. However, the final northern segment (in Massachusetts) is owned by the Massachusetts Bay Transportation Authority.

Stations

Amtrak owns Pennsylvania Station in New York and Union Station in Washington.

Current Amtrak Service

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 lines run along the Northeast Corridor:

• Acela Express - Boston South Station to Washington Union Station (high-speed rail)
• Cardinal - New York Penn Station to Washington Union Station, continuing to Chicago, Illinois
• Carolinian - New York Penn Station to Washington Union Station, continuing to Charlotte, North Carolina
• Clocker - New York Penn Station to Philadelphia 30th Street Station
• Crescent - New York Penn Station to Washington Union Station, continuing to New Orleans, Louisiana
• Keystone - New York Penn Station to Philadelphia 30th Street Station, continuing to Harrisburg, Pennsylvania
• Lake Shore Limited - Boston South Station to Boston Back Bay Station, continuing to Chicago, Illinois
• Metroliner - New York Penn Station to Washington Union Station
• Palmetto - New York Penn Station to Washington Union Station, continuing to Savannah, Georgia
• Regional - Boston South Station to Washington Union Station, continuing to Newport News, Virginia and with a branch to Springfield, Massachusetts (stops at every Amtrak station on the route)
• Silver Meteor - New York Penn Station to Washington Union Station, continuing to Miami, Florida
• Silver Star - New York Penn Station to Washington Union Station, continuing to Miami, Florida
• Three Rivers - New York Penn Station to Philadelphia 30th Street Station, continuing to Chicago, Illinois
• Vermonter - Washington Union Station to New Haven Union Station, continuing to St. Albans, Vermont

Non-Amtrak Commuter Rail Services

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

• MARC in Maryland
• SEPTA in Pennsylvania and southern New Jersey
• NJ Transit in New Jersey, New York, and Pennsylvania
• Metro-North in New York, Connecticut
• Shore Line East in eastern Connecticut
• MBTA in Massachusetts

Many other bus and rail commuter services interchange passengers with Amtrak and these commuter agencies at stations along the Northeast Corridor.

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. 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
  • Walker's Dock
  • Wamphassuc Crossing
  • MP 133.4 - Latimer Point Road
  • Broadway
• Groton, Connecticut
  • School Street (the first quad-gate installation in the United States, in summer 1998)
• New London, Connecticut
  • Governor Winthrop Boulevard
  • State Street
  • Bank Street Connector
• Waterford, Connecticut
  • Miner's Lane
