The New York City Subway is a heavy-rail public transit system serving four of the five boroughs of New York City. The present New York City Subway system inherited the systems of the Interborough Rapid Transit Company (IRT), BrooklynâÂÂManhattan Transit Corporation (BMT), and the Independent Subway System (IND). New York City has owned the IND since its inception; the BMT and IRT were taken over by the city in 1940. The former IRT system is now known as the A Division, while the B Division is the combined former BMT and IND systems.
In the New York City Subway nomenclature, a "line" refers to the physical trackage that is used by numbered or lettered "services", which change periodically. Today, the division or company names are not used publicly, while the line names may occasionally be used.
Nomenclature
In the nomenclature of the subway, the terms "line" and "service" are not interchangeable with each other. While in popular usage the word "line" is often used synonymously with "service" (even sometimes on the website of the MTA), this list will use the formal usage of the term "line."
A line is the physical structure and tracks that trains run over. Each section of the system is assigned a unique line name that begins with a division (IRT, BMT or IND), which is its pre-unification division when applicable. For example, the line under Eighth Avenue is the IND Eighth Avenue Line. Some lines have changed names (and even divisions), but this happens relatively infrequently.
By contrast, a service refers to the route that a train takes across the various lines. A service can operate along several lines and even along different divisions. For example, the service operates along the IND Queens Boulevard Line as well as the BMT Broadway Line and the BMT Fourth Avenue Line.
Each service is assigned a color. Since 1979, each service's color corresponds to the line it primarily uses in Midtown ManhattanâÂÂdefined as the trunk line. There are three exceptions: the IND Crosstown Line, which does not carry services to Manhattan, is colored ; the BMT Nassau Street Line, which runs only through Lower Manhattan, is colored ; and all shuttles are colored . The list of trunk lines and colors is shown in the table below.
Line listing
There are currently rail lines. The Archer Avenue Lines and the 63rd Street Lines are each classified as two separate lines due to their structure: both lines have distinct sections that are chained as BMT and the IND lines.
In the list below, lines with colors next to them indicate trunk lines, which determine the colors that are used for services' route bullets and diamonds, as well as shuttle service lines. The opening date refers to the opening of the first section of track for the line. In the "division" column, the current division is followed by the original division in parentheses.
Inter-division connections
The following list shows the connections between the different divisions of the New York City Subway.
Purpose-built
These connections can be used by trains in revenue service:
This connection is not for revenue service due to the differing widths of the trains:
Yards
These connections are located within the subway's rail yards and are not intended for revenue service.
To the national rail network
Unused connections in the same division
In some places, there are track connections within the same division that are unused in regular service.
Brooklyn
Manhattan
Queens
Unused center tracks
Many of the New York City Subway's lines have express tracks, unused in regular service and generally only used for re-routes.
The Bronx
Brooklyn
Manhattan
Queens
Non-underground sections
Despite âÂÂsubwayâ implying underground travel, the following segments are located above ground or at grade level and comprise about 40% of the trackage.
The Bronx
Brooklyn
Manhattan
Queens
Trackage
At minimum, in normal revenue service, all lines have two tracks, with one exception: the BMT Franklin Avenue Line has a single track between Franklin Avenue and Park Place.
Three-tracked portions
The New York City Subway has fewer triple track sections than it has quadruple track sections. These sections are listed below. The third track, when in use, is generally for peak-direction express service or reroutes, with exceptions noted below.
- IRT BroadwayâÂÂSeventh Avenue Line () from south of Van Cortlandt ParkâÂÂ242nd Street to north of Dyckman Street and from north of 145th Street to north of 96th Street

- IRT Lenox Avenue Line () at 135th Street â center track is not usable in revenue service
- IRT Jerome Avenue Line () â entire line, except for Woodlawn
- IRT Dyre Avenue Line () â entire line
- IRT Pelham Line () â entire line
- IRT Flushing Line () â from 33rd StreetâÂÂRawson Street to FlushingâÂÂMain Street
- IRT New Lots Line () at Junius Street â center track is not usable in revenue service

- BMT Sea Beach Line ( to )
Additionally, there are several pocket tracks in the subway where the line temporarily widens from two to three tracks, such as east of Eighth Avenue on the BMT Canarsie Line, and south of Court Square on the IND Crosstown Line.
Four-tracked portions
Quadruple-tracked portions of track are fairly common in the subway system. This makes it unique among most metro systems in the world, as most others only have two tracks per line. Generally, these portions are a pair of express and a pair of local tracks unless otherwise noted.
- Trunk lines:
- IND Sixth Avenue Line between Broadwayâ Lafayette Street and 47thâÂÂ50th Streets
- IND Eighth Avenue Line between Chambers StreetâÂÂWorld Trade Center and 168th Street, and again at Dyckman Street (two local tracks and two tracks leading to the 207th Street Yard)
- IRT Lexington Avenue Line between Brooklyn BridgeâÂÂCity Hall and 125th Street
- IRT BroadwayâÂÂSeventh Avenue Line between Chambers and 96th Streets
- BMT Broadway Line between Canal Street and 57th StreetâÂÂSeventh Avenue
- BMT Nassau Street Line at Chambers Street (originally a four platform station)
- Branch lines:
- :Manhattan branches:
- :#63rd Street Lines at Lexington Avenue (two levels of one-direction tracks, with both levels containing one track each of IND and BMT, with connections between lines on both levels)
- :#Chrystie Street Connection (one pair IND and one pair BMT)
- :#Manhattan Bridge (one pair of tracks on each of the north and south sides of the bridge)
- :Queens branches:
- :#IND Queens Boulevard Line east of Queens Plaza

The Bronx has no four-tracked lines. Pocket tracks are not included.
Defunct lines
The following New York City Subway lines are either entirely defunct or have major portions no longer in service. Defunct spur lines with one station, such as the South Ferry loops, are not included in this list, nor are surface transit lines.
Vestiges of former lines
- IRT White Plains Road Line: Just north of the Third AvenueâÂÂ149th Street station, exiting the tunnel portal, one can see the initial framework of the IRT Third Avenue Line. There used to be a connection from the White Plains Road line to the Third Avenue El, which ran south across the Harlem River to Manhattan.
- IRT White Plains Road Line: The other end of the Third Avenue El connected to the White Plains Road line at the lower level of the Gun Hill Road station (closed 1973). Also on the White Plains Road line is the remnant of the short section of track to the original Bronx Park terminal.
- IRT Jerome Avenue Line: North of the 161st StreetâÂÂYankee Stadium station is the framework for the connection from the IRT Ninth Avenue Line.
- IRT Dyre Avenue Line: The Dyre Avenue Line was part of the New York, Westchester, and Boston Railway; it continued north beyond EastchesterâÂÂDyre Avenue to White Plains and Port Chester; and south of the present connection to the White Plains Road line at East 180th Street, to 133rd Street where it ran alongside the New Haven Railroad. The platforms of the NYW&B station are still visible at East 180th Street station and are sometimes used to store trains. The structure south of East 180th Street ends abruptly at Lebanon Street.
- IRT Flushing Line: Part of the trackway from the Queensboro Bridge and the IRT Second Avenue Line is still visible at the east end of Queensboro Plaza.
- BMT Nassau Street Line/BMT Broadway Line: The BMT Nassau Street Line used to connect to the south side of the Manhattan Bridge north of Chambers Street. The trackways were disconnected from the Manhattan Bridge after the Chrystie Street Connection opened. Also, heading northbound over the Manhattan Bridge north side, an abandoned tunnel is visible before entering Grand Street. Heading northbound on the south side, the remains of the tunnel to the BMT Nassau Street Line loop is briefly visible. This area was reconfigured as part of the Chrystie Street Connection.
- BMT Fulton Street Line: Trackways are still visible at BMT Canarsie Line stations at Broadway Junction and Atlantic Avenue. Framework for the el was up until early 1998, visible at the Franklin Avenue Shuttle station at Franklin AvenueâÂÂFulton Street. The structure served as a pedestrian walkway and was demolished in 1998 when the station and the Franklin Avenue Line was rebuilt as a single-tracked line.
- BMT Fulton Street Line: On the IND Fulton Street Line heading westbound from 80th Street, one can see the stub end of the old BMT Fulton Street Line continuing straight ahead while the IND Fulton Street Line curves into Grant Avenue, an underground station.
- BMT Culver Line (now IND Culver Line): At Ninth Avenue and at Ditmas Avenue, the original Culver line connected. The trackway is visible at Ditmas Avenue and the ramps are visible at Ninth Avenue.
- BMT Jamaica Line: West of Gates Avenue, one can see where the structure turned onto Lexington Avenue to head toward the Brooklyn Bridge. The structure is only visible from street level.
- BMT Jamaica Line: West of Marcy Avenue, the BMT Jamaica Line veers right onto the Williamsburg Bridge while the original structure continues straight ahead.
- BMT Jamaica Line: East of 121st Street, the 144th Street BMT powerhouse and 168th Street station house still exist along Jamaica Avenue.
- The LIRR's Rockaway Beach Branch runs from the White Pot Junction to just east of Rockaway Boulevard, where the IND Rockaway Line begins.
