List of New York City Subway lines

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), Brooklyn–Manhattan 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 used by trains that are used by numbered or lettered "services"; the services that run on certain lines change periodically. Today, the division or company names are not used publicly, while the line names may occasionally be used.

Nomenclature

Summarize
Perspective

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[1]), 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 R 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 Manhattan[original research?]—defined as the trunk line. There are three exceptions: the IND Crosstown Line, which does not carry services to Manhattan, is colored light green; the BMT Nassau Street Line, which runs only through Lower Manhattan, is colored brown; and all shuttles are colored dark gray.[2] The list of trunk lines and colors is shown in the table below.

Line listing

Summarize
Perspective

There are currently 36 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

Summarize
Perspective

The following list shows the connections between the different divisions of the New York City Subway.[14][dubious discuss]

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.

Trackage

Summarize
Perspective

A map of the New York City Subway by the number of tracks on line segments.

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[original research?]. These sections are listed below. The third track, when in use, is generally for peak-direction express service or reroutes, with exceptions noted below.

  1. IRT Broadway–Seventh Avenue Line (1 train) from south of Van Cortlandt Park–242nd Street to north of Dyckman Street and from north of 145th Street to north of 96th Street
  2. IRT White Plains Road Line (2 and 5 trains) from south of Wakefield–241st Street to east of Third Avenue–149th Street
  3. IRT Lenox Avenue Line (2 and 3 trains) at 135th Street – center track is not usable in revenue service
  4. IRT Jerome Avenue Line (4 train) – entire line, except for Woodlawn
  5. IRT Dyre Avenue Line (5 train) – entire line
  6. IRT Pelham Line (6 and <6> trains) – entire line
  7. IRT Flushing Line (7 and <7> trains) – from 33rd Street–Rawson Street to Flushing–Main Street
  8. IRT New Lots Line (2, 3, 4, and 5 trains) at Junius Street – center track is not usable in revenue service
  9. IND Fulton Street Line (A train) – from west of 80th Street to west of Ozone Park–Lefferts Boulevard; the westernmost portion of this track goes to Pitkin Yard
  10. BMT West End Line (D, R, and W trains) – from Ninth Avenue to Bay 50th Street
  11. IND Concourse Line (B and D trains) – from 145th Street to Bedford Park Boulevard
  12. IND Culver Line (F and <F> trains) – from south of Church Avenue to Avenue X
  13. BMT Jamaica Line (J, M, and Z trains) – from Marcy Avenue to Broadway Junction. Also, at 111th Street, the center track is not usable in revenue service
  14. BMT Canarsie Line (L train) at East 105th Street – easternmost track is not usable in revenue service
  15. BMT Astoria Line (N and W trains) – from east of Queensboro Plaza to south of Astoria–Ditmars Boulevard
  16. IND Crosstown Line (G train) at Bedford–Nostrand Avenues – middle track can be used to turn trains coming from either direction
  17. BMT Broadway Line at Whitehall Street – middle track used to turn southbound (W) and northbound (R) trains
  18. BMT Sea Beach Line (Eighth Avenue to 86th Street)

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.

  1. Trunk lines:
    1. IND Sixth Avenue Line between Broadway– Lafayette Street and 47th–50th Streets
    2. IND Eighth Avenue Line between Chambers Street–World Trade Center and 168th Street, and again at Dyckman Street (two local tracks and two tracks leading to the 207th Street Yard)
    3. IRT Lexington Avenue Line between Brooklyn Bridge–City Hall and 125th Street
    4. IRT Broadway–Seventh Avenue Line between Chambers and 96th Streets
    5. BMT Broadway Line between Canal Street and 57th Street–Seventh Avenue
    6. BMT Nassau Street Line at Chambers Street (originally a four platform station)
  2. Branch lines:
    Manhattan branches:
    1. 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)
    2. Chrystie Street Connection (one pair IND and one pair BMT)
    3. Manhattan Bridge (one pair of tracks on each of the north and south sides of the bridge)
    Queens branches:
    1. IND Queens Boulevard Line east of Queens Plaza
    2. IND Rockaway Line north of Jamaica Bay
    3. Archer Avenue Lines from Sutphin Boulevard and east (two levels of paired tracks: all IND on one, all BMT on the other, without connections between lines)
    4. IRT Flushing Line and BMT Astoria Line at Queensboro Plaza (two levels of one-direction tracks, with both levels containing one track each of IRT and BMT, with a non-revenue connection between lines on upper level)
    Brooklyn branches:
    1. IRT Eastern Parkway Line (entire line)
    2. IND Culver Line north of Church Avenue
    3. IND Fulton Street Line between Hoyt–Schermerhorn Streets and Euclid Avenue
    4. BMT Brighton Line between Ocean Parkway and Prospect Park
    5. BMT Fourth Avenue Line north of 59th Street
    6. Manhattan Bridge (one pair of tracks on each of the north and south sides of the bridge)

The Bronx has no four-tracked lines. Pocket tracks are not included.

Notes

  1. The route of the original IRT line, the first underground New York City rapid transit line, began at City Hall in the south, followed the IRT Lexington Avenue Line to 33rd Street, turned west on 42nd Street to Grand Central, followed the IRT 42nd Street Shuttle to Times Square, turned north on Broadway to 50th Street, followed the IRT Broadway–Seventh Avenue Line and terminated at 145th Street.
  2. The formation of the IND Culver Line occurred when the IND "recaptured" (e.g. New York City took over lines it had built for private companies) the trackage rights of the BMT Culver Line in 1954, connecting Ditmas Avenue to Church Avenue, the terminus of the IND Brooklyn Line.
  3. The IRT Dyre Avenue Line was formed from the purchase of abandoned New York, Westchester and Boston Railway trackage in 1941.
  4. For the extension of the IND Fulton Street Line in 1956, the IND "recaptured" the trackage rights of the BMT Fulton Street Line, connecting Hudson Street–80th Street to Grant Avenue.
  5. The IND Rockaway Line was formed from the purchase of some trackage from the Long Island Rail Road's Rockaway Park Branch and Far Rockaway Branch in 1955.
  6. At Wilson Avenue, the southbound track is above ground while the northbound one is at-grade. However, the land directly adjacent to the subway station makes the lower level northbound track look as though it is underground, and the upper level southbound track look at-grade.
