TheNortheast Corridor (NEC) is an electrified railroad line in theNortheast megalopolis of the United States. Owned primarily byAmtrak, it runs fromBoston in the north toWashington, D.C., in the south, with major stops inProvidence,New Haven,Stamford,New York City,Newark,Trenton,Philadelphia,Wilmington, andBaltimore. The NEC is roughly paralleled byInterstate 95 for most of its length. Carrying more than 2,200 trains a day,^[2] it is the busiest passenger rail line in the United States by ridership and service frequency.^[3]

The corridor is used by many Amtrak trains, including the high-speedAcela (formerlyAcela Express), intercity trains, and severallong-distance trains. Most of the corridor also has frequentcommuter rail service, operated by theMBTA (Keolis),CT Rail,Metro-North Railroad,Long Island Rail Road,New Jersey Transit,SEPTA, andMARC. While large through freights have not run on the NEC since the early 1980s, some sections still carry smaller local freights operated byCSX,Norfolk Southern,CSAO,Providence and Worcester,New York and Atlantic, andCanadian Pacific. CSX and NS partly own their routes.

Long-distance Amtrak services that use the Northeast Corridor include theCardinal,Crescent, andSilver Meteor trains, which reach 125 mph (201 km/h), as well as itsAcela trains, which reach 150–160 mph (240–260 km/h) in parts ofMassachusetts,Rhode Island, andNew Jersey. Some express trains operated by MARC that reach 125 mph (201 km/h) also operate on the Northeast Corridor.Acela can travel the 225 mi (362 km) between New York City and Washington, D.C., in under three hours, and the 229 mi (369 km) between New York and Boston in under 3.5 hours.^[4][5]

In 2012, Amtrak proposed improvements to enable "true" high-speed rail on the corridor, which would have roughly halved travel times at an estimated cost of $151 billion.^[6][7]

Most of what is now called the Northeast Corridor was built, piece by piece, by several railroads constructed as early as the 1830s. Before 1900, their routes had been consolidated as two long and unconnected stretches, each of them a part of a major railroad. Anchored in Washington, D.C., the stretch owned by thePennsylvania Railroad, approached New York City from the south. Anchored at Boston, the stretch owned by theNew Haven Railroad enteredNew York State fromConnecticut. The former terminated at New Jerseyferry slips across the Hudson River from Manhattan Island.^[8] The latter extended to the Bronx, where it continued into Manhattan via trackage rights on theNew York and Harlem Railroad. It also reached the Bronx via theHarlem River and Port Chester Railroad, which extended to the Bronx from the New Haven atNew Rochelle.^[9]

From 1903 to 1917, the two railroads undertook a number of projects that connected their lines and completed, in effect, the Northeast Corridor. These included theNew York Tunnel Extension, which extended from New Jersey to Long Island (and was composed of theManhattan Transfer station, theNorth River Tunnels, a newPennsylvania Station, theEast River Tunnels), theNew York Connecting Railroad, and theHell Gate Bridge. Combined, these constituted a stretch that started just outside ofNewark, New Jersey, on the Pennsylvania Railroad side, and connected with theHarlem River and Port Chester Railroad (and thus New Rochelle) on the New Haven side. With the opening of the Hell Gate Bridge in 1917, this final connecting stretch, and thus the Northeast Corridor itself, was complete.^{[citation needed]}

With the 1968 creation ofPenn Central, which was a combination of those two railroads and the New York Central Railroad, the entire corridor was under the control of a single entity for the first time. After successor Penn Central’s 1970 bankruptcy, the corridor was almost entirely subsumed by the subsequently-createdAmtrak on May 1, 1971.^{[citation needed]}

In 1899,William J. Wilgus, the New York Central Railroad (NYC)'s chief engineer, proposedelectrifying the lines leading fromGrand Central Terminal and the split atMott Haven, using athird rail power system devised byFrank J. Sprague. Electricity was in use on some branch lines of the NYNH&H forinterurban streetcars viathird rail ortrolley wire.^[17] An accident in thePark Avenue Tunnel near the present Grand Central Terminal that killed 17 people on January 8, 1902, was blamed on smoke fromsteam locomotives; the resulting outcry led to a push for electric operation inManhattan.^[18][19][20]

The NH announced in 1905 that it would electrify its main line from New York toStamford, Connecticut.^{[citation needed]} Along with theconstruction of Grand Central Terminal, which was opened in 1913, the NYC electrified its lines. On September 30, 1906, the NYC conducted a test of suburbanmultiple unit service toHigh Bridge station on theHudson Line;^{[21]: 97 [22]} regular service began on December 11.^[23][24]Electric locomotives began serving Grand Central on February 15, 1907,^[21]: 115 and all NYC passenger service into Grand Central was electrified on July 1, 1907.^[24][25] NH electrification began in July toNew Rochelle, August toPort Chester and October the rest of the way to Stamford.^[26] Steam trains last operated into Grand Central on June 30, 1908: the deadline after which steam trains were banned in Manhattan.^{[21]: 55–56} Subsequently, all NH passenger trains into Manhattan were electrified. In June 1914, the NH electrification was extended toNew Haven, which was the terminus of electrified service for over 80 years.^[27]

The PRR was building itsPennsylvania Station and electrified approaches, which were served by the PRR's lines inNew Jersey and theLong Island Rail Road (LIRR). LIRR electric service began in 1905 on theAtlantic Branch fromdowntown Brooklyn pastJamaica,^[28][29] and in June 1910 on the branch toLong Island City: part of the main line to Penn Station.^[29] Penn Station opened on September 8, 1910, for LIRR trains^[30] and November 27 for the PRR;^[31] trains of both railroads were powered byDC electricity from a third rail. PRR trains changed engines (electric to/from steam) atManhattan Transfer; passengers could also transfer there toH&M trains to downtown Manhattan.^{[citation needed]}

On July 29, 1911, NH began electric service on itsHarlem River Branch: a suburban branch that would become a main line with the completion of theNew York Connecting Railroad and itsHell Gate Bridge.^[32][33] The bridge opened on March 9, 1917,^[16] but was operated by steam with an engine change atSunnyside Yard east of Penn Station until 1918.^{[citation needed]}

Electrification north of New Haven to Providence and Boston had been planned by the NH, and authorized by the company's board of directors shortly before the United States enteredWorld War I. This plan was not carried out because of the war and the company's financial problems. Electrification north of New Haven did not occur until the 1990s, by Amtrak, using a 60 Hz system.

In 1905, the PRR began to electrify its suburban lines at Philadelphia: an effort that eventually led to11 kV, 25 Hz AC catenary from New York and Washington.^[34] Electric service began in September 1915, withmultiple unit trains west toPaoli on the PRR Main Line (now theKeystone Corridor).^[35] Electric service toChestnut Hill (now theChestnut Hill West Line), including a stretch of the NEC, began on March 30, 1918.^{[citation needed]} Local electric service toWilmington, Delaware, on the NEC began on September 30, 1928, and toTrenton, New Jersey, on June 29, 1930.^{[citation needed]}

Electrified service betweenExchange Place, theJersey City terminal, andNew Brunswick, New Jersey, began on December 8, 1932, including the extension of Penn Station electric service from Manhattan Transfer.^{[citation needed]} On January 16, 1933, the rest of the electrification between New Brunswick and Trenton opened, giving a fully-electrified line between New York and Wilmington. Trains to Washington began running under electricity to Wilmington on February 12, 1933, with the engine-change moved from Manhattan Transfer to Wilmington.^{[citation needed]} The same was done on April 9, 1933, for trains running west from Philadelphia, with the change point moved to Paoli.^{[citation needed]}

In 1933, the electrification south of Wilmington was stalled by theGreat Depression, but the PRR got a loan from thePublic Works Administration to resume work.^[36] The tunnels at Baltimore were rebuilt as part of the project. Electric service between New York and Washington began on February 10, 1935.^[37] On April 7, the electrification of passenger trains was complete, with 639 daily trains: 191 hauled by locomotives and the other 448 under multiple-unit power.^{[citation needed]} New York–Washington electric freight service began on May 20, 1935, after the electrification of freight lines in New Jersey and Washington,DC.^{[citation needed]} Extensions toPotomac Yard across thePotomac River from Washington, as well as several freight branches along the way, were electrified in 1937 and 1938.^{[citation needed]} The Potomac Yard retained its electrification until 1981.^{[citation needed]}

In the 1930s, PRR equipped the New York–Washington line withPulse code cab signaling. Between 1998 and 2003, this system was overlaid with anAlstomAdvanced Civil Speed Enforcement System (ACSES), using track-mounted transponders similar to theBalises of the modernEuropean Train Control System.^[38] The ACSES enabled Amtrak to implementpositive train control to comply with theRail Safety Improvement Act of 2008.^{[citation needed]}

In December 1967, theUAC TurboTrain set a speed record for a production train: 170.8 miles per hour (274.9 km/h) betweenNew Brunswick andTrenton, New Jersey.^[39]

In February 1968, PRR merged with its rivalNew York Central Railroad to form thePenn Central (PC).^[40] Penn Central was required to absorb the New Haven in 1969 as a condition of the merger.^[41]

On September 21, 1970, all New York–Boston trains except theTurboservice were rerouted into Penn Station from Grand Central;^{[citation needed]} theTurboservice moved on February 1, 1971, for cross-platform transfers to the Metroliners.^[42]

In 1971, Amtrak began operations, and various state governments took control of portions of the NEC for their commuter transportation authorities. In January, theCommonwealth of Massachusetts bought theAttleboro/Stoughton Line in Massachusetts,^{[citation needed]} later operated by theMassachusetts Bay Transportation Authority. The same month, the New York State Metropolitan Transportation Authority bought, and Connecticut leased, from Penn Central their sections of theNew Haven Line, betweenWoodlawn, New York, andNew Haven, Connecticut.^[42]

In 1973, theRegional Rail Reorganization Act opened the way for Amtrak to buy sections of the NEC not already been sold to these commuter transportation authorities. These purchases by Amtrak were controversial at the time, and theDepartment of Transportation blocked the transaction and withheld purchase funds for several months until Amtrak granted it control over reconstruction of the corridor.^[43]

In February 1975, the Preliminary System Plan forConrail proposed to stop running freight trains on the NEC betweenGroton, Connecticut, andHillsgrove, Rhode Island, but this clause was rejected the following month by theU.S. Railway Association.^[44]

By April 1976, Amtrak owned the entire NEC except Boston to the RI state line, which is owned by the Commonwealth of Massachusetts, and New Haven to New Rochelle, New York, which is owned by the States of Connecticut and New York. Amtrak still operates and maintains the portion in Massachusetts, but the line from New Haven toNew Rochelle, New York, is operated by theMetro-North Railroad, which has hindered the establishment of high-speed service.^[45][46]

In 1976,Congress authorized an overhaul of the system between Washington and Boston.^[47] Called the Northeast Corridor Improvement Project (NECIP), it included safety improvements, modernization of the signaling system byGeneral Railway Signal, and new Centralized Electrification and Traffic Control (CETC) control centers byChrysler at Philadelphia, New York and Boston.^{[citation needed]} It allowed more trains to run faster and closer together, and set the stage for laterhigh-speed operation. NECIP also introduced theAEM-7 locomotive, which lowered travel times and became the most successful engine on the Corridor. The NECIP set travel time goals of 2 hours and 40 minutes between Washington and New York, and 3 hours and 40 minutes between Boston and New York.^[48] These goals were not met because of the low level of funding provided by the Reagan Administration and Congress in the 1980s.^[49]

Electrification between New Haven and Boston was to be included in the 1976Railroad Revitalization and Regulatory Reform Act.^[47]

The lastgrade crossings between New York and Washington were closed about 1985; eleven grade crossings remain in Connecticut.

In the 1990s, Amtrak upgraded the NEC north of New Haven, CT to get it ready for the high-speedAcela Express trains.^[49] Dubbed the Northeast High Speed Rail Improvement Program (NHRIP), the effort eliminatedgrade crossings, rebuilt bridges and modified curves. Concreterailroad ties replaced wood ties, and heaviercontinuous welded rail (CWR) was laid-down.^[50][51] In 1996, Amtrak began installing electrification infrastructure along the 157 miles (253 kilometres) of track between New Haven and Boston.

Service with electric locomotives between New Haven and Boston began on January 31, 2000.^[52] The project took four years and cost close to $2.3 billion: $1.3 billion for the infrastructure improvements and close to $1 billion for both the newAcela Express trainsets and theBombardier–Alstom HHP-8 locomotives.^[53]

On December 11, 2000, Amtrak began operating its higher-speedAcela Express service.^[54] Fastest travel time byAcela is three and a half hours between Boston and New York, and two hours forty-five minutes between New York and Washington, D.C.^[55]

In 2005, there was talk in Congress of splitting the Northeast Corridor, which was opposed by then-acting Amtrak presidentDavid Gunn. The plan, supported by the Bush administration, would "turn over the Northeast Corridor – the tracks from Washington to Boston that are the railroad's main physical asset – to a federal-state consortium."^[56]

With the passage of thePassenger Rail Investment and Improvement Act of 2008, the Congress established theNortheast Corridor Commission (NEC Commission) in the U.S. Department of Transportation to facilitate mutual cooperation and planning and to advise Congress on Corridor rail and development policy. The commission members include USDOT, Amtrak and the Northeast Corridor states.

In October 2010, Amtrak released "A Vision for High-Speed Rail on the Northeast Corridor," an aspirational proposal for dedicated high-speed rail tracks between Washington, D.C., and Boston.^[57] Many of these proposals are unfunded.

In August 2011 theUnited States Department of Transportation committed $450 million to a six-year project to support capacity increases on one of the busiest segments on the NEC: a 24-mile (39 km) section betweenNew Brunswick andTrenton, passing through Princeton Junction. TheNext Generation High-Speed project is designed to upgrade electrical power, signal systems and overhead catenary wires to improve reliability and increase speeds up to 160 mph (260 km/h), and, after the purchase of new equipment, up to 186 miles per hour (299 km/h).^[58] In September 2012, speed tests were conducted usingAcela trainsets, achieving a speed of 165 miles per hour (266 km/h).^[59][60] The improvements were scheduled to be completed in 2016, but, due to delays, the project had not been completed until 2020.^[61][62]

In 2012, theFederal Railroad Administration began developing a master plan for bringing high-speed rail to the Northeast Corridor titled NEC FUTURE, and released the finalenvironmental impact statement in December 2016.^[63] Multiple potential alignments north of New York City were studied.^[64] The proposed upgrades have not been funded.

Eleven minutes after leaving30th Street Station in Philadelphia on May 12, 2015, a year-oldACS-64 locomotive (#601) and all sevenAmfleet I coaches of Amtrak's northboundNortheast Regional (TR#188) derailed at 9:21pm atFrankford Junction in thePort Richmond section of the city, while entering a 50 mph (80 km/h) speed limited (but at the time non-ATC protected)4° curve at 106 mph (171 km/h), killing eight and injuring more than 200 (eight critically) of the 238 passengers and five crew on board as well as causing the suspension of all Philadelphia–New York NEC service for six days.^[65][66]

This was the deadliest crash on the Northeast Corridor since 16 died when Amtrak's Washington–BostonColonial (TR#94)rear-ended three stationaryConrail locomotives at Gunpow Interlocking near Baltimore on January 4, 1987.^[67] Frankford Junction curve was the site of a previousfatal accident on September 6, 1943, when an extra section of thePRR's Washington to New YorkCongressional Limited derailed there, killing 79 and injuring 117 of the 541 on board.^[68]

The NEC is a cooperative venture between Amtrak and various state agencies. Amtrak owns the track between Washington andNew Rochelle,New York, a northern suburb of New York City.^{[citation needed]} The segment from New Rochelle to New Haven is owned by the states of New York and Connecticut;Metro-North Railroad commuter trains operate there.^{[citation needed]} Amtrak owns the tracks north of New Haven to the border between Rhode Island and Massachusetts. The final segment from the border north to Boston is owned by the Commonwealth of Massachusetts.^{[citation needed]}

At just over 453 miles (729 km), the Northeast Corridor is the longest electrified rail corridor in the United States.^[69] Most electrified railways in the country are for rapid transit or commuter rail use; theKeystone Corridor is the only other electrified intercity mainline.^{[citation needed]}

Currently, the corridor uses three catenary systems. From Washington, D.C., to Sunnyside Yard (just east of New York Penn Station),Amtrak's 25 Hz traction power system (originally built by the Pennsylvania Railroad) supplies 12 kV at 25 Hz. From Sunnyside to Mill River (just east of New Haven station), theformer New Haven Railroad's system, since modified by Metro-North, supplies 12.5 kV at 60 Hz. From Mill River to Boston, the much newer60 Hz traction power system supplies 25 kV at 60 Hz. All of Amtrak's electric locomotives canswitch between these systems.

In addition to catenary, theEast River Tunnels have 750 V DCthird rail forLong Island Rail Road trains, and theNorth River Tunnels have third rail for emergency use only.

In 2006, several high-profile electric-power failures delayed Amtrak and commuter trains on the Northeast Corridor up to five hours.^[70] Railroad officials blamed Amtrak's funding woes for the deterioration of the track and power supply system, which in places is almost a hundred years old. These problems have decreased in recent years after tracks and power systems were repaired and improved.^[71]

In September 2013, one of two feeder lines supplying power to theNew Haven Line failed, while the other feeder was disabled for service. The lack of electrical power disrupted trains on Amtrak andMetro-North Railroad, which share the segment in New York State.^[72]

There are 109 active stations on the Northeast Corridor; 30 are used by Amtrak. All but three (Kingston,Westerly, andMystic) see commuter service. Amtrak ownsPennsylvania Station in New York,30th Street Station in Philadelphia,Penn Station in Baltimore, andUnion Station in Washington.^{[citation needed]}

The entire Northeast Corridor has 11grade crossings, all in southeasternNew London County, Connecticut. The remaining grade crossings are along a part of the line that hugs the shore ofLong Island Sound. Some of these crossings constitute the only points of access to waterfront communities and businesses otherwise disconnected from the road network. As such, eliminating them would requiregrade separation to maintain access. Six of the grade crossings havefour-quadrant gates withinduction loop sensors, which allow vehicles stopped on the tracks to be detected in time for an oncoming train to stop. The remaining five grade crossings, 3 nearNew London Union Station and two in Stonington, have dual gates.^[73]

FRA rules limit track speeds on the corridor to 80 miles per hour (130 km/h) over conventional crossings and 95 miles per hour (153 km/h) over crossings with four-quadrant gates and vehicle detection tied into the signal system.^[74]

The New York to New Haven line has long been completely grade-separated, and the last grade crossings between Washington and New York were eliminated in the 1980s.^{[citation needed]} In 1994, during planning for electrification and high-speedAcela Express service between New Haven and Boston, a law was passed requiringUSDOT to plan for the elimination of all remaining crossings (unless impractical or unnecessary) by 1997.^[75] Some lightly used crossings were simply closed, while most were converted into bridges or underpasses. Only thirteen remained by 1999, of which lightly used crossings inOld Lyme, Connecticut, andExeter, Rhode Island, were soon closed.^[76]

Despite six nonfatal accidents in the previous sixteen years, there was substantial local opposition to closing the remaining 11 crossings. Outright closing the crossing would eliminate the sole access points to several of the places they served, while grade separation would be expensive and require land takings.^[76] Instead, the crossings were supplied with additional protections. In 1998, School Street inGroton was the first four-quadrant gate installation in the country with vehicle detection sensors tied into the line's signal system.^[77] It cost $1 million rather than the $4 million for a bridge.^[78] Seven more crossings received similar installations in 1999 and 2000; only the three in New London (which are on a tight curve with speed limits under 30 miles per hour (48 km/h)) did not.^[79]

On September 28, 2005, a southboundAcela Express struck a car at Miner Lane inWaterford, Connecticut, the first such incident since the additional protections were implemented.^[80] The train was approaching the crossing at approximately 70 miles per hour (110 km/h) when the car reportedly rolled under the lowered crossing gate arms too late for the sensor system to fully stop the train. The driver and one passenger were killed on impact; the other passenger died nine days later from injuries sustained in the crash. The gates were later inspected and declared to have been functioning properly at the time of the incident.^[81] The incident drew public criticism about the remaining grade crossings along the busy line.^[82]

Crossing are listed east to west.^[73]

In 2003, Amtrak accounted for about 14% of intercity trips between the cities served by the NEC and its branches (the rest were taken by airline, automobile, orbus).^[92] A 2011 study estimated that in 2010 Amtrak carried 6% of the Boston–Washington traffic, compared to 80% for automobiles, 8–9% for intercity bus, and 5% for airlines.^[93] Amtrak's share of the air or rail passenger traffic between New York City and Boston has grown from 20 percent to 54 percent since 2001, and 75 percent between New York City and Washington, D.C.^[94]

These Amtrak trains serve NEC stations and run at least partially on the corridor:

• Acela: high-speed rail Boston–Washington, D.C.
• Cardinal: New York–Chicago via Washington, D.C. (Wednesdays, Fridays, & Sundays only)
• Carolinian: New York–Charlotte, North Carolina
• Crescent: New York–New Orleans
• Keystone Service: higher-speed railHarrisburg, Pennsylvania – New York
• Northeast Regional: higher-speed rail (This service qualifies as high speed rail on the 125mph stretch between New Brunswick and Princeton Junction.) Boston/Springfield/New York–Washington D.C./Richmond/Newport News/Norfolk/Roanoke, Virginia
• Palmetto:Savannah, Georgia – New York
• Pennsylvanian:Pittsburgh–New York via NEC andPhiladelphia to Harrisburg Main Line
• Silver Meteor:Miami–New York
• Vermonter:St. Albans, Vermont – Washington, D.C., via NEC andNew Haven–Springfield Line

Seven other Amtrak trains terminate at NEC stations, but do not use any NEC infrastructure outside the terminus:

• AmtrakHartford Line: operated in conjunction withConnDOT, runs across Amtrak-ownedNew Haven–Springfield line fromSpringfield Union toNew Haven Union, the latter of which uses NEC infrastructure.

Six Amtrak services operate via theEmpire Corridor, a line largely owned by CSX, with other sections owned by Metro-North Railroad and Amtrak. It meets the NEC atNew York Penn Station.

• Adirondack: runs from New York Penn toMontreal Central
• Berkshire Flyer: higher-speed rail from New York Penn toAlbany–Rensselaer and theJoseph Scelsi Intermodal Transportation Center inPittsfield, Massachusetts
• Empire Service: higher-speed rail from New York Penn toAlbany–Rensselaer andNiagara Falls
• Ethan Allen Express: runs fromBurlington Union to New York Penn
• Lake Shore Limited: runs fromChicago Union to New York Penn; also has a branch to the NEC's terminus atBoston South
• Maple Leaf: runs from New York Penn toToronto Union

TheFloridian, which travels betweenChicago Union andMiami, intersects with the Northeast Corridor atWashington Union.

Due to the wide availability of theNortheast Regional,Keystone Service, andAcela, as well as commuter rail, most long- and medium-haul trains operating along the New York-Washington leg of the NEC do not allow local travel between NEC stations. In most cases, long- and medium-haul trains only stop to discharge passengers from Washington (and in some cases,Alexandria) northward, and to receive passengers from Newark to Washington. This policy is intended to keep seats available for passengers making longer trips. TheVermonter andPalmetto are the only medium- and long-haul trains that allow local travel in both directions between New York and Washington. The southboundCarolinian allows local travel daily, while the northboundCarolinian only allows local travel on Sundays, Thursdays, and Fridays. Additionally, the medium-haulPennsylvanian allows local NEC travel, but this train leaves the corridor in Philadelphia and does not travel all the way to Washington.

In addition to Amtrak, several commuter rail agencies operate passenger service using the NEC tracks:

• Providence/Stoughton Line:Wickford Junction–Boston
• Franklin/Foxboro Line:Readville–Boston
• Needham Line:Forest Hills–Boston
• Framingham/Worcester Line:Back Bay Station–Boston

The only section north of New York that does not have commuter service is the 43 miles between Wickford Junction and New London.

• Hartford Line:New Haven Union Station–New Haven-State Street
• Shore Line East:Stamford–New London, Connecticut

• New Haven Line:New Rochelle, New York–New Haven, Connecticut
• Danbury Branch:Stamford–Norwalk, Connecticut
• Waterbury Branch:Bridgeport–Stratford, Connecticut

• City Terminal Zone:Sunnyside Yard, Queens–New York

• Northeast Corridor Line:Trenton, NJ–New York
• North Jersey Coast Line:Rahway, NJ–New York
• Morristown Line,Gladstone Branch,Montclair-Boonton Line:Kearny Connection–New York
• Raritan Valley Line:Hunter Connection–New York
• Atlantic City Line:30th Street Station–Frankford Junction

• Trenton Line: Philadelphia–Trenton, New Jersey
• Airport Line: 30th Street Station–Southwest Philadelphia
• Media/Wawa Line: 30th Street Station–Arsenal Junction
• Chestnut Hill West Line: 30th Street Station–North Philadelphia Station
• Wilmington/Newark Line:Newark, Delaware–Philadelphia

• Penn Line: Washington, D.C.–Perryville, Maryland, via Baltimore Penn Station

Freight trains operate on parts of the NEC throughtrackage rights. Prior to the 1970s whenAmtrak took over all passenger service, the NEC routinely saw lengthy freight trains sometimes numbering over one hundred cars traversing great lengths of the corridor. All freight operations ultimately came under the control ofPenn Central in the late 1960s and laterConrail upon its formation in 1976, however Amtrak, whose ridership was steadily increasing began demanding heavier taxes for longer trains. Ultimately Conrail began reducing freight service to only small, local trains on certain sections of the corridor where most needed once longer freights began causing congestion and bigger delays with passenger service.

Currently,Norfolk Southern Railway operates over the line south of Philadelphia.CSX Transportation has rights from New York to New Haven; in Massachusetts; and inMaryland fromLandover, where itsLandover Subdivision joins the NEC, toBowie, where itsPope's Creek Subdivision leaves it. Between Philadelphia and New York,Conrail Shared Assets Operations operates as a local switching and terminal company for CSX and Norfolk Southern. TheProvidence and Worcester Railroad operates local freight service from New Haven into Rhode Island and hasoverhead trackage rights from New Haven to New York over theHell Gate Bridge toFresh Pond Junction.^[95] Additionally, theCanadian Pacific Kansas City and theNew York and Atlantic Railway both have trackage rights over the Hell Gate Bridge in order to connect with their own routes near New York.^[96]

In February 2011, Amtrak announced plans for theGateway Project betweenNewark Penn Station andNew York Penn Station.^[97] The planned project would create a high-speed alignment across theNew Jersey Meadowlands and under theHudson River, including the replacement of thePortal Bridge, a bottleneck.

In May 2011, a $294.7-million federal grant was awarded to fix congestion at Harold Interlocking, the USA's second-busiestrail junction afterSunnyside Yard. The work will lay tracks to the New York Connecting Railroadright of way, allowing Amtrak trains arriving from or bound forNew England to avoidNJ Transit andLong Island Rail Road trains.^[98][99] Financing for the project was jeopardized in July 2011 by theHouse of Representatives, which voted to divert the funding to unrelated projects.^[100] The project was then funded by FRA and the MTA.^[101] As of 2018^[update], the interlocking is being reconstructed for LIRR'sEast Side Access project.^[102][103]

In August 2011, Congress obligated $450 million to a six-year project to add capacity on one of the busiest segments on the NEC inNew Jersey.^[58] The project is designed to upgrade electrical power, signal systems and catenary wires on a 24-mile (39 km) section betweenNew Brunswick andTrenton to improve reliability, increase speeds up to 160 mph (260 km/h), and support more frequent high-speed service.^{[104][105][106]} The improvements were scheduled to be completed in 2016, but have been delayed repeatedly.^[107] The track work is one of several projects planned for the "New Jersey Speedway" section of the NEC, which include a new station atNorth Brunswick, theMid-Line Loop (a flyover for reversing train direction), and the re-construction ofCounty Yard, to be done in coordination withNJ Transit.^[108]Acela trains began operating at speeds up to 150 mph (240 km/h) betweenPrinceton Junction and New Brunswick in June 2022. With the planned introduction of theAvelia Liberty in 2025, speeds will increase to 160 miles per hour (260 km/h).^[109]

On August 26, 2016, Vice PresidentJoe Biden announced a $2.45 billion federal loan package to pay for newAcela equipment and upgrades to the NEC. The loans will finance 28 trainsets to replace the existing fleet. The trains are being built byAlstom inHornell andRochester, New York. Passenger service using the new trains had been expected to begin in 2024, but implementation was highly delayed.^[110] The first new trainsets entered service on August 28, 2025.^[111][112] The current fleet is expected to be retired when all the replacements have been delivered. Amtrak plans to repay the loans through increased NEC passenger revenue.^[113]

TheConnecticut Department of Transportation plans to replace a three-mile stretch of track inBridgeport,Stratford, andMilford, including the reconstruction of eight bridges (one in Bridgeport and seven in Stratford), catenary replacement, the reconstruction of oneinterlocking for high-speed track changes, and the construction of an additional new high-speed interlocking.^[114][115] These improvements will allow Metro-North and Amtrak trains to travel at 90 mph (140 km/h) instead of the current 70 mph (110 km/h) limit.^[116][117] The $385 million project is planned to begin in 2025, with completion estimated in December 2028.^[114][118]

InMilford andStratford,Connecticut, the 1906Devon Bridge over theHousatonic River causes delays and speed restrictions.^[119] The four-trackbascule bridge is planned to be rehabilitated and eventually replaced, improving reliability and reducing travel times.^[120] The Connecticut Department of Transportation was awarded $119.3 million for interim repairs to the bridge in 2023.^[118] Repairs are scheduled to run from June 2025 until June 2027. A new bridge to replace the existing span is to be built from October 2030 to August 2036.^[119] Amtrak was awarded up to $246 million inInfrastructure Investment and Jobs Act funds in November 2023 for the design of a replacement for the span. Amtrak will contribute an additional $16 million, while the state of Connecticut will provide $45 million.^[118] The replacement bridge is being designed for a top speed of 70 mph (110 km/h), up from the current 40 mph (64 km/h) limit on the existing bridge.^[121]
