New York City subway

Alfred Ely Beach built the first demonstration for an underground transit system in New York City in 1869 and opened it in February 1870. His Beach Pneumatic Transit only extended 312 feet (95 m) under Broadway in Lower Manhattan operating from Warren Street to Murray Street and exhibited his idea for an atmospheric railway as a subway. The tunnel was never extended for political and financial reasons. Today, no part of this line remains as the tunnel was completely within the limits of the present-day City Hall station under Broadway. The Great Blizzard of 1888 helped demonstrate the benefits of an underground transportation system. A plan for the construction of the subway was approved in 1894, and construction began in 1900. Even though the underground portions of the subway had yet to be built, several above-ground segments of the modern-day New York City Subway system were already in service by then. The oldest structure still in use opened in 1885 as part of the BMT Lexington Avenue Line in Brooklyn and is now part of the BMT Jamaica Line. The oldest right-of-way, which is part of the BMT West End Line near Coney Island Creek, was in use in 1864 as a steam railroad called the Brooklyn, Bath and Coney Island Rail Road.

The first underground line of the subway opened on October 27, 1904, almost 36 years after the opening of the first elevated line in New York City (which became the IRT Ninth Avenue Line). The 9.1-mile (14.6 km) subway line, then called the "Manhattan Main Line", ran from City Hall station northward under Lafayette Street (then named Elm Street) and Park Avenue (then named Fourth Avenue) before turning westward at 42nd Street. It then curved northward again at Times Square, continuing under Broadway before terminating at 145th Street station in Harlem. Its operation was leased to the Interborough Rapid Transit Company (IRT), and over 150,000 passengers paid the 5-cent fare ($2 in 2025 dollars ) to ride it on the first day of operation.

By the late 1900s and early 1910s, the lines had been consolidated into two privately owned systems, the IRT and the Brooklyn Rapid Transit Company (BRT, later Brooklyn–Manhattan Transit Corporation, BMT). The city built most of the lines and leased them to the companies. The first line of the city-owned and operated Independent Subway System (IND) opened in 1932. …

Many rapid transit systems run relatively static routings, so that a train "line" is more or less synonymous with a train "route". In New York City, routings change often, for various reasons. Within the nomenclature of the subway, the "line" describes the physical railroad track or series of tracks that a train "route" uses on its way from one terminal to another. "Routes" (also called "services") are distinguished by a letter or a number and "lines" have names. Trains display their route designation.

There are 25 train services in the subway system, including three short shuttles. Each route has a color and a local or express designation representing the Manhattan trunk line of the service. New York City residents seldom refer to services by color (e.g., "blue line" or "green line") but out-of-towners and tourists often do.

The 1, C, G, L, M, R, and W trains are fully local and make all stops. The 2, 3, 4, 5, A, B, D, E, F, N, and Q trains have portions of express and local service. J, Z, 6, and 7 trains vary by direction, day, or time of day. The letter S is used for three shuttle services: Franklin Avenue Shuttle, Rockaway Park Shuttle, and 42nd Street Shuttle.

Though the subway system operates on a 24-hour basis, during late night hours some of the designated routes do not run, run as a shorter route (often referred to as the "shuttle train" version of its full-length counterpart) or run with a different stopping pattern. These are usually indicated by smaller, secondary route signage on station platforms. Because there is no nightly system shutdown for maintenance, tracks and stations must be maintained while the system is operating. This work sometimes necessitates service changes during midday, overnight hours, and weekends.

When parts of lines are temporarily shut down for construction purposes, the transit authority can substitute free shuttle buses (using MTA Regional Bus Operations bus fleet) to replace the routes that would normally run on these lines. The Transit Authority announces planned service changes through its website, via placards that are posted on station and interior subway-car walls, and through its Twitter page.

Since 2025, the official transit maps of the New York City Subway have been based on a 1972 design by Massimo Vignelli. …

Out of the 472 stations, 470 are served 24 hours a day. Underground stations in the New York City Subway are typically accessed by staircases going down from street level. Many of these staircases are painted in a common shade of green, with slight or significant variations in design. Other stations have unique entrances reflective of their location or date of construction. Several station entrance stairs, for example, are built into adjacent buildings. Nearly all station entrances feature color-coded globe or square lamps signifying their status as an entrance. The current number of stations is smaller than the peak of the system. In addition to the demolition of former elevated lines, which collectively have resulted in the demolition of over a hundred stations, other closed stations and unused portions of existing stations remain in parts of the system.

Many stations in the subway system have mezzanines. Mezzanines allow for passengers to enter from multiple locations at an intersection and proceed to the correct platform without having to cross the street before entering. Inside mezzanines are fare control areas, where passengers physically pay their fare to enter the subway system. In many older stations, the fare control area is at platform level with no mezzanine crossovers. Many side platformed elevated stations also have platform-level fare control with no common station house between directions of service.

Upon entering a station, passengers may use station booths (formerly known as token booths) or vending machines to buy their fare, which is currently stored in a MetroCard or OMNY card. Each station has at least one booth, typically located at the busiest entrance. After swiping the card at a turnstile, customers enter the fare-controlled area of the station and continue to the platforms. Inside fare control are "Off-Hours Waiting Areas", which consist of benches and are identified by a yellow sign.

Only five stations (Eastchester–Dyre Avenue, Baychester Avenue, Gun Hill Road, Pelham Parkway and Morris Park) of the whole NYC subway do not have at least a booth that is staffed 24 hours per day, seven days per week.

A typical subway station has waiting platforms ranging from 480 to 600 feet (150 to 180 m) long. Some are longer. Platforms of former commuter rail stations—such as those on the IND Rockaway Line, are even longer. …

In November 2016, the New York City Subway had 6712 cars on the roster. A typical New York City Subway train consists of 8 to 11 cars, although shuttles can have as few as two, and the train can range from 150 to 600 feet (46 to 183 m) in length. The system maintains two separate fleets of cars, one for the A Division routes and another for the B Division routes. A Division equipment is approximately 8 feet 9 inches (2.67 m) wide and 51 feet 4 inches (15.65 m) long, whereas B Division equipment is about 10 feet (3.05 m) wide and either 60 feet 6 inches (18.44 m) or 75 feet (22.86 m) long. 75-foot cars cannot be used over the BMT Eastern Division in regular service due to tight turning radii on Eastern Division lines; the turning radii for curves on Eastern Division lines are as tight as 175 feet (53 m). Each train typically has two staff members on board: an operator at the front, who drives the train, and a conductor at the center, who makes announcements, assists operators, and is responsible for passenger safety and service.

Cars purchased by the City of New York since the inception of the IND and the other divisions beginning in 1948 are identified by the letter "R" followed by a number; e.g.: R32. This number is the contract number under which the cars were purchased. Cars with nearby contract numbers (e.g.: R1 through R9, or R26 through R29, or R143 through R179) may be relatively identical, despite being purchased under different contracts and possibly built by different manufacturers.

From 2000 to 2024, the R142, R142A, R143, R160, R179, R188 and R211 were placed into service. These cars are collectively known as New Technology Trains (NTTs) due to modern innovations such as information screens, recorded train announcements, and the ability to facilitate Communication-Based Train Control (CBTC).

As part of the 2017–2020 MTA Financial Plan, 600 subway cars will have electronic display signs installed to improve customer experience.

Riders pay a single fare to enter the subway system and may transfer between trains at no extra cost until they exit via station turnstiles; the fare is a flat rate regardless of how far or how long the rider travels. Thus, riders must tap a contactless payment card or smartphone on an OMNY reader (or swipe a MetroCard with remaining balance) upon entering the subway system, but not a second time upon leaving.

As of December 2025, nearly all fares are paid by OMNY, and as of January 4, 2026, the base fare is $3. Reduced fares are available for the elderly and people with disabilities. In addition, there is a weekly fare cap for subways and buses; after passengers pay 12 fares with the same fare-payment medium in a 7-day period, any additional trips during the same period are free.

Fares were stored in a money room at 370 Jay Street in Downtown Brooklyn starting in 1951, when the building opened as a headquarters for the New York City Board of Transportation. The building is close to the lines of all three subway divisions (the IRT, BMT, and IND) and thus was a convenient location to collect fares, including tokens and cash, via money trains. Passageways from the subway stations, including a visible door in the Jay Street IND station, lead to a money sorting room in the basement of the building. The money trains were replaced by armored trucks in 2006.

In June 1993, a fare system called the MetroCard was introduced, which allows riders to use magnetic stripe cards that store the value equal to the amount paid to a subway station booth clerk or vending machine. The MetroCard was enhanced in 1997 to allow passengers to make free transfers between subways and buses within two hours and several MetroCard-only transfers between subway stations were added in 2001. With the addition of unlimited-ride MetroCards in 1998, the New York City Transit system was the last major transit system in the United States with the exception of BART in San Francisco to introduce passes for unlimited bus and rapid transit travel. …
