The [[New York City Subway]] is a [[Heavy rail|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 (New York City Subway)|A Division]], while the [[B Division (New York City Subway)|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==
{{main|New York City Subway 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 [[Metropolitan Transportation Authority|MTA]]<ref>[http://mta.info/nyct/service/index.html Subway Line Information] {{webarchive|url=https://web.archive.org/web/20120516060049/http://www.mta.info/nyct/service/index.html |date=May 16, 2012 }}</ref>), 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 ([[Interborough Rapid Transit Company|IRT]], [[Brooklyn–Manhattan Transit Corporation|BMT]] or [[Independent Subway System|IND]]), which is its pre-unification division when applicable. For example, the line under [[Eighth Avenue (Manhattan)|Eighth Avenue]] is the [[IND Eighth Avenue Line]]. Some lines have changed names (and even divisions), but this happens relatively infrequently.

By contrast, [[List of New York City Subway services|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 {{NYCS|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]]{{or|is this an inference based on some pattern or is this documented somewhere?|date=February 2024}}—defined as the ''trunk line''. There are three exceptions: the [[IND Crosstown Line]], which does not carry services to Manhattan, is colored {{NYCS const|color|lightgreen}}; the [[BMT Nassau Street Line]], which runs only through [[Lower Manhattan]], is colored {{NYCS const|color|brown}}; and all [[S (New York City Subway service)|shuttles]] are colored {{NYCS const|color|darkgray}}.<ref name=Hertz-Gothamist>{{cite web | first=Dave | last=Hogarty | url=http://gothamist.com/2007/08/03/michael_hertz_d.php | title=Michael Hertz, Designer of the NYC Subway Map | work=[[Gothamist]] | date=August 3, 2007 | access-date=July 4, 2009 | url-status=dead | archive-url=https://web.archive.org/web/20090818012400/http://gothamist.com/2007/08/03/michael_hertz_d.php | archive-date=August 18, 2009 | df=mdy-all }}</ref> The list of trunk lines and colors is shown in the table below.

{{NYCS const/table|style=margin:0.2em auto}}

== Line listing ==

There are currently {{NYCS const|lines}} [[rail line]]s. 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 [[New York City Subway chaining|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.<ref>{{cite web|url=http://www.nycsubway.org/wiki/Subway_FAQ:_Interconnections_Between_IRT_and_IND-BMT_Divisions |title=Subway FAQ: Interconnections Between IRT and IND–BMT Divisions |publisher=www.nycsubway.org |access-date=November 12, 2013}}</ref>{{dubious|this whole section feels a bit arbitrary - the ref is for A division/B division connections yet other types are listed|date=February 2024}}

===Purpose-built===

These connections can be used by trains in revenue service:
*[[60th Street Tunnel Connection]], also known as the 11th Street Cut (Queens) (BMT/IND) ({{NYCS 60th Connection}} train)
*[[63rd Street Line]]s (Manhattan) (BMT/IND)
*[[Coney Island–Stillwell Avenue (New York City Subway)|Coney Island–Stillwell Avenue]] station (BMT/IND) (originally all BMT) ({{NYCS Stillwell}} trains)
*[[Chrystie Street Connection]] (Manhattan) (BMT/IND) via the [[Manhattan Bridge]] ({{NYCS Manhattan Bridge north}} trains) and via the [[Williamsburg Bridge]] ({{NYCS Chrystie Williamsburg}} train)

This connection is not for revenue service due to the differing widths of the trains:
*[[BMT Astoria Line|Astoria Line]] / [[IRT Flushing Line|Flushing Line]] (Queens) (BMT/IRT)

===Yards===

These connections are located within the [[New York City Subway yards|subway's rail yards]] and are not intended for revenue service.
*[[207th Street Yard]] (Manhattan) (IND/IRT); trains from the [[IND Eighth Avenue Line]] and [[IRT Broadway–Seventh Avenue Line]]
*[[Coney Island Complex]] (Brooklyn) (BMT/IND); trains from the [[IND Culver Line]], [[BMT Sea Beach Line]] and [[BMT West End Line]]
*[[Concourse Yard]] (Bronx) (IND/IRT); trains from the [[IND Concourse Line]] and [[IRT Jerome Avenue Line]]
*[[Linden Shops (New York City Subway)|Linden Yard]] (Brooklyn) (BMT/IRT/[[Long Island Rail Road|LIRR]]); trains from the [[BMT Canarsie Line]] and [[IRT New Lots Line]]

===Other===

*[[BMT West End Line]] / [[South Brooklyn Railway]] (Brooklyn) (BMT/Mainline RR)

===Unused connections in the same division===
In some places, there are track connections within the same division that are unused in regular service.<ref>{{cite web|url=http://www.nycsubway.org/wiki/Subway_FAQ:_Unused_Track_Connections |title=Subway FAQ: Unused Track Connections |publisher=www.nycsubway.org |access-date=November 12, 2013}}</ref>

====Brooklyn====
*At [[Coney Island–Stillwell Avenue (New York City Subway)|Coney Island–Stillwell Avenue]], see above.
*At [[Broadway Junction (New York City Subway)|Broadway Junction]], there is an unused flyover between the [[BMT Canarsie Line]] and the [[BMT Jamaica Line]].
*At [[Prospect Park (BMT Brighton Line)|Prospect Park]], the tracks of the [[BMT Franklin Avenue Line]] become the local tracks of the [[BMT Brighton Line]].
*At [[DeKalb Avenue (BMT Fourth Avenue Line)|DeKalb Avenue]], there is an unused connection between the [[BMT Brighton Line]] and the [[BMT Broadway Line]] via the Montague Tunnel.

====Manhattan====
*At [[West Fourth Street–Washington Square (New York City Subway)|West Fourth Street–Washington Square]], there is an unused connection between the local tracks of the [[IND Eighth Avenue Line]] and those of the [[IND Sixth Avenue Line]].
*Between [[Bowling Green (IRT Lexington Avenue Line)|Bowling Green]] and the [[South Ferry loops (New York City Subway)|South Ferry loops]], the IRT Lexington Avenue Line and the IRT Broadway–Seventh Avenue Line have crossovers on the [[balloon loop]] tracks.
*On the [[42nd Street Shuttle]], there are track connections to the [[IRT Broadway–Seventh Avenue Line]] at the west end and the [[IRT Lexington Avenue Line]] at the east end. It is not possible to operate through service on this line (i.e. one cannot go from the Broadway –Seventh Avenue Line to the Lexington Avenue Line using the shuttle tracks and vice versa), though the tracks are used to transport trains to and from [[Livonia Yard]] in Brooklyn.
*South of [[Broad Street (BMT Nassau Street Line)|Broad Street]] on the [[BMT Nassau Street Line]], the two-track line widens to four tracks. The two inner tracks are used to store and turn {{NYCS Nassau south}} trains, while the two outer tracks continue to the [[Montague Street Tunnel]] and to the [[BMT Fourth Avenue Line]] in Brooklyn.

====Queens====
*On the [[IND Rockaway Line]], a single track connects the branches of the wye at Hammels, south of [[Broad Channel (IND Rockaway Line)|Broad Channel]], this was used previously for [[Rockaway Park Shuttle#Service history|round-robin shuttle]] service and emergency {{NYCS|H}} service.

==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.<ref>{{cite web|url=http://www.nycsubway.org/wiki/Subway_FAQ:_Unused_Express_Tracks |title=Subway FAQ: Unused Express Tracks |publisher=www.nycsubway.org |access-date=November 12, 2013}}</ref>

===The Bronx===
*[[IRT Jerome Avenue Line]]: Single center track between [[149th Street–Grand Concourse (IRT Jerome Avenue Line)|149th Street–Grand Concourse]] and [[Woodlawn (IRT Jerome Avenue Line)|Woodlawn]]. Some northbound {{NYCS|4}} trains in the morning and afternoon rush hours operate express from [[167th Street (IRT Jerome Avenue Line)|167th Street]] until [[Burnside Avenue (IRT Jerome Avenue Line)|Burnside Avenue]], where they short-turn.
*[[IRT White Plains Road Line]]: Single center track between [[East 180th Street (IRT White Plains Road Line)|East 180th Street]] and [[Wakefield–241st Street (IRT White Plains Road Line)|Wakefield–241st Street]].
*[[IRT Dyre Avenue Line]]: Combinations of track and right of way between the flyover and [[Eastchester–Dyre Avenue (IRT Dyre Avenue Line)|Dyre Avenue]].
*[[IRT Pelham Line]]: Single center track between [[Parkchester (IRT Pelham Line)|Parkchester]] and [[Pelham Bay Park (IRT Pelham Line)|Pelham Bay Park]].
*[[IRT Broadway–Seventh Avenue Line]]: Single center track between [[Dyckman Street (IRT Broadway–Seventh Avenue Line)|Dyckman Street]] and [[Van Cortlandt Park–242nd Street (IRT Broadway–Seventh Avenue Line)|242nd Street]].

===Brooklyn===
*[[BMT Sea Beach Line]]: One center track between [[86th Street (BMT Sea Beach Line)|86th Street]] and [[Eighth Avenue (BMT Sea Beach Line)|Eighth Avenue]]. These were originally a pair of tracks which were briefly used by the {{NYCS|NX}} service in 1967–1968; in 1999, one of the tracks was rehabilitated and the other was disconnected from the line leaving it unusable. The track is used occasionally for reroutes in either direction and possibly equipment testing. In the past, these tracks have been used to store rolling stock that are about to be scrapped.
*[[BMT West End Line]]: Single center track between [[Ninth Avenue (BMT West End Line)|Ninth Avenue]] and [[Bay 50th Street (BMT West End Line)|Bay 50th Street]]. Occasionally used for reroutes in either direction.
*[[BMT Brighton Line]]: Two center tracks between [[Brighton Beach (BMT Brighton Line)|Brighton Beach]] and [[Ocean Parkway (BMT Brighton Line)|Ocean Parkway]]. These are used for layups and for terminating/turning {{NYCS|B}} trains but are listed here since they are a continuation of the express tracks from the Brighton line, and exist through Ocean Parkway station.
*[[IND Culver Line]]: Single center track between [[Church Avenue (IND Culver Line)|Church Avenue]] and [[Avenue X (IND Culver Line)|Avenue X]].
*[[BMT Jamaica Line]]: Single center track between [[Myrtle Avenue (BMT Jamaica Line)|Myrtle Avenue]] and [[Broadway Junction (New York City Subway)|Broadway Junction]].

===Manhattan===
*[[IRT Broadway–Seventh Avenue Line]]: Single center track between [[96th Street (IRT Broadway–Seventh Avenue Line)|96th Street]] and [[145th Street (IRT Broadway–Seventh Avenue Line)|145th Street]].
*[[IRT Lenox Avenue Line]]: Single center track at [[135th Street (IRT Lenox Avenue Line)|135th Street]].

===Queens===
*[[BMT Astoria Line]]: Single center track between [[39th Avenue (BMT Astoria Line)|39th Avenue]] and [[Astoria–Ditmars Boulevard (BMT Astoria Line)|Astoria –Ditmars Boulevard]]. This track was last used for {{NYCS|W}} trains in the peak direction, and being unpopular with residents, was discontinued on January 15, 2002.
*[[IND Fulton Street Line]] and [[IND Rockaway Line]]: On the Fulton Street Line, a single center track between [[Rockaway Boulevard (IND Fulton Street Line)|Rockaway Boulevard]] and west of [[88th Street (IND Fulton Street Line)|88th Street]] (the track continues through [[80th Street (IND Fulton Street Line)|80th Street]] but leads only to the Pitkin Yard), and two center tracks from north of Aqueduct to south of [[Howard Beach–JFK Airport (IND Rockaway Line)|Howard Beach–JFK Airport]] on the IND Rockaway Line.

==Trackage==
[[File:NYC Subway number of tracks.svg|thumb|right|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 (BMT Franklin Avenue Line)|Franklin Avenue]] and [[Park Place (BMT Franklin Avenue Line)|Park Place]].

===Three-tracked portions===
The New York City Subway has fewer [[double track#Triple track|triple track]] sections than it has [[quadruple track]] sections{{or|by what metric?|date=February 2024}}. 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 Broadway–Seventh Avenue Line]] ({{NYCS trains|Broadway-Seventh north}}) from south of [[Van Cortlandt Park–242nd Street (IRT Broadway–Seventh Avenue Line)|Van Cortlandt Park–242nd Street]] to north of [[Dyckman Street (IRT Broadway–Seventh Avenue Line)|Dyckman Street]] and from north of [[145th Street (IRT Broadway–Seventh Avenue Line)|145th Street]] to north of [[96th Street (IRT Broadway–Seventh Avenue Line)|96th Street]]
# [[IRT White Plains Road Line]] ({{NYCS trains|White Plains}}) from south of [[Wakefield–241st Street (IRT White Plains Road Line)|Wakefield–241st Street]] to east of [[Third Avenue–149th Street (IRT White Plains Road Line)|Third Avenue–149th Street]]
# [[IRT Lenox Avenue Line]] ({{NYCS trains|Lenox}}) at [[135th Street (IRT Lenox Avenue Line)|135th Street]] – center track is not usable in revenue service
# [[IRT Jerome Avenue Line]] ({{NYCS trains|Jerome}}) – entire line, except for [[Woodlawn (IRT Jerome Avenue Line)|Woodlawn]]
# [[IRT Dyre Avenue Line]] ({{NYCS trains|Dyre}}) – entire line
# [[IRT Pelham Line]] ({{NYCS trains|Pelham}}) – entire line
# [[IRT Flushing Line]] ({{NYCS trains|Flushing}}) – from [[33rd Street–Rawson Street (IRT Flushing Line)|33rd Street–Rawson Street]] to [[Flushing–Main Street (IRT Flushing Line)|Flushing–Main Street]]
# [[IRT New Lots Line]] ({{NYCS trains|New Lots}}) at [[Junius Street (IRT New Lots Line)|Junius Street]] – center track is not usable in revenue service
# [[IND Fulton Street Line]] ({{NYCS trains|Fulton east}}) – from west of [[80th Street (IND Fulton Street Line)|80th Street]] to west of [[Ozone Park–Lefferts Boulevard (IND Fulton Street Line)|Ozone Park–Lefferts Boulevard]]; the westernmost portion of this track goes to [[List of New York City Subway yards#Pitkin Yard|Pitkin Yard]]
# [[BMT West End Line]] ({{NYCS trains|West End}}) – from [[Ninth Avenue (BMT West End Line)|Ninth Avenue]] to [[Bay 50th Street (BMT West End Line)|Bay 50th Street]]
# [[IND Concourse Line]] ({{NYCS trains|Concourse}}) – from [[145th Street (IND Eighth Avenue Line)|145th Street]] to [[Bedford Park Boulevard (IND Concourse Line)|Bedford Park Boulevard]]
# [[IND Culver Line]] ({{NYCS trains|Culver IND south}}) – from south of [[Church Avenue (IND Culver Line)|Church Avenue]] to [[Avenue X (IND Culver Line)|Avenue X]]
# [[BMT Jamaica Line]] ({{NYCS trains|Jamaica west}}) – from [[Marcy Avenue (BMT Jamaica Line)|Marcy Avenue]] to [[Broadway Junction (BMT Jamaica Line)|Broadway Junction]]. Also, at [[111th Street (BMT Jamaica Line)|111th Street]], the center track is not usable in revenue service
# [[BMT Canarsie Line]] ({{NYCS trains|Canarsie}}) at [[East 105th Street (BMT Canarsie Line)|East 105th Street]] – easternmost track is not usable in revenue service
# [[BMT Astoria Line]] ({{NYCS trains|Astoria}}) – from east of [[Queensboro Plaza (New York City Subway)|Queensboro Plaza]] to south of [[Astoria–Ditmars Boulevard (BMT Astoria Line)|Astoria–Ditmars Boulevard]]
# [[IND Crosstown Line]] ({{NYCS trains|Crosstown}}) at [[Bedford–Nostrand Avenues (IND Crosstown Line)|Bedford–Nostrand Avenues]] – middle track can be used to turn trains coming from either direction
# [[BMT Broadway Line]] at [[Whitehall Street - South Ferry (BMT Broadway Line)|Whitehall Street]] – middle track used to turn southbound ({{NYCS|W}}) and northbound ({{NYCS|R}}) trains
# [[BMT Sea Beach Line]] ({{stl|NYCS|Eighth Avenue|Sea Beach}} to {{stl|NYCS|86th Street|Sea Beach}})

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 (BMT Canarsie Line)|Eighth Avenue]] on the [[BMT Canarsie Line]], and south of [[Court Square (IND Crosstown Line)|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 Broadway– Lafayette Street and 47th–50th Streets
## [[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)
## [[IRT Lexington Avenue Line]] between Brooklyn Bridge–City Hall and 125th Street
## [[IRT Broadway–Seventh Avenue Line]] between Chambers and 96th Streets
## [[BMT Broadway Line]] between Canal Street and 57th Street–Seventh 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
#:#[[IND Rockaway Line]] north of Jamaica Bay
#:#[[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)
#:#[[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:'''
#:#[[IRT Eastern Parkway Line]] (entire line)
#:#[[IND Culver Line]] north of Church Avenue
#:#[[IND Fulton Street Line]] between Hoyt–Schermerhorn Streets and Euclid Avenue
#:#[[BMT Brighton Line]] between Ocean Parkway and Prospect Park
#:#[[BMT Fourth Avenue Line]] north of 59th Street
#:#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.

== Defunct lines ==

The following New York City Subway lines are either entirely defunct or have major portions no longer in service. Defunct [[spur line]]s with one station, such as the [[South Ferry loops (New York City Subway)|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 Avenue–149th Street (IRT White Plains Road Line)|Third Avenue–149th 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 (IRT White Plains Road Line)|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 Third Avenue Line)|Bronx Park terminal]].
*[[IRT Jerome Avenue Line]]: North of the [[161st Street–Yankee Stadium (IRT Jerome Avenue Line)|161st Street–Yankee 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 [[NYW&B|New York, Westchester, and Boston Railway]]; it continued north beyond [[Eastchester–Dyre Avenue (IRT Dyre Avenue Line)|Eastchester–Dyre Avenue]] to White Plains and Port Chester; and south of the present connection to the White Plains Road line at [[East 180th Street (IRT White Plains Road Line)|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 (New York City Subway)|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 (BMT Nassau Street Line)|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 (IND Sixth Avenue Line)|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 (BMT Canarsie Line)|Broadway Junction]] and [[Atlantic Avenue (BMT Canarsie Line)|Atlantic Avenue]]. Framework for the el was up until early 1998, visible at the [[Franklin Avenue Shuttle]] station at [[Franklin Avenue–Fulton Street (New York City Subway)|Franklin Avenue–Fulton 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 (IND Fulton Street Line)|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 (IND Fulton Street Line)|Grant Avenue]], an underground station.
*[[BMT Culver Line]] (now [[IND Culver Line]]): At [[Ninth Avenue (BMT West End Line)|Ninth Avenue]] and at [[Ditmas Avenue (IND Culver Line)|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 (BMT Jamaica Line)|Gates Avenue]], one can see where the structure turned onto [[BMT Lexington Avenue Line|Lexington Avenue]] to head toward the Brooklyn Bridge. The structure is only visible from street level.
*BMT Jamaica Line: West of [[Marcy Avenue (BMT Jamaica Line)|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 (BMT Jamaica Line)|121st Street]], the 144th Street BMT powerhouse and [[168th Street (BMT Jamaica Line)|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.
