The Independent Subway System (IND or ISS), formerly known as the Independent City-Owned Subway System (ICOS) or the Independent City-Owned Rapid Transit Railroad,[1] was a rapid transit rail system in New York City that is now part of the New York City Subway. It was first constructed as the "Eighth Avenue Line" in Manhattan in 1932.[2]

One of three rail networks that became part of the modern New York City subway, the IND was intended to be fully owned and operated by the municipal government, in contrast to the privately operated or jointly-funded Interborough Rapid Transit Company (IRT) and Brooklyn–Manhattan Transit Corporation (BMT) companies. It was merged with these two networks in 1940.[1]

The original IND service lines are the modern subway's A, B, C, D, E, F and G services. In addition, the BMT's M and R now run partly on IND trackage. The Rockaway Park Shuttle supplements the A service. For operational purposes, the IND and BMT lines and services are referred to jointly as the B Division.[1]

Nomenclature

Until 1940, it was known as the Independent City-Owned Subway System (ICOS), Independent Subway System (ISS), or Independent City-Owned Rapid Transit Railroad. It became known as the IND after unification of the subway lines in 1940; the name IND was assigned to match the three-letter acronyms that the IRT and BMT used.[1]

The first IND line was the Eighth Avenue Line in Manhattan, opened on September 10, 1932; for a while the whole system was colloquially known as the Eighth Avenue Subway. The original IND system was entirely underground in the four boroughs that it served, with the exception of a short section of the IND Culver Line containing two stations spanning the Gowanus Canal in the Gowanus section of Brooklyn.[1]

History

In the early 1920s, Mayor John Hylan proposed a complex series of city-owned and operated rapid transit lines to compete with the BMT and IRT, especially their elevated lines.[3][4] The New York City Transit Commission was formed in 1921 to develop a plan to reduce overcrowding on the subways. The original plans included:[1]

These lines were completely built as planned. All but a short portion of the Culver Line (over the Gowanus Canal) are underground.[1]

Opening and progress through 1933

First Manhattan trunk line, 1932

World Trade Center station

On September 10, 1932, the Eighth Avenue Line opened from 207th Street to Chambers Street, inaugurating the IND. In February 1933 the Cranberry Street Tunnel opened, along with the Eighth Avenue Line from Chambers Street to Jay Street – Borough Hall. On the northern end of the construction, in the Bronx, the connecting Concourse Line opened on July 1, 1933 from 205th Street to 145th Street.[2] On the IND's opening day, it had a relatively small subway car fleet of 300 cars, while the IRT had 2,281 subway and 1,694 elevated cars, and the BMT had 2,472 cars.[1]

While the IND Eighth Avenue Line opened for operation, other portions of the Independent were under construction, some of which were five underwater crossings:

The new subway was built using 1,000,000 cubic yards of concrete, and 150,000 tons of steel. The roadbed of the new subway was expected to last 30 years.

There was some vandalism on the IND's opening day, with some of the uptown stations being broken into by people who clogged turnstile slots with gum and other objects. Two months after the IND opened for business, exits at 95th, 97th, and 105th Street were closed due to theft.

First branch lines

In October 1932, the Queens Boulevard Line opened from Jackson Heights – Roosevelt Avenue to the lower level of 50th Street on the Eighth Avenue Line, connecting the Queens and Manhattan lines. In Queens, the Crosstown Line opened from Queens Plaza to Nassau Avenue.[1]

On October 7, 1933, the Culver Line opened from Jay Street to Church Avenue.[1][5]

Second Manhattan trunk line, 1936–1937

On January 1, 1936, the Sixth Avenue Line opened from West Fourth Street (where it splits from the Eighth Avenue Line) to East Broadway.[6][7][8] During construction, streetcar service along Sixth Avenue was terminated. The city could either restore it upon the completion of construction or abandon it immediately; as the city wanted to tear down the IRT Sixth Avenue Line right away and save on the costs of shoring it up while construction proceeded underneath it, the IRT Sixth Avenue Line was purchased for $12.5 million and terminated by the city on December 5, 1938., with the steel from the el sold to Japan. Two years later, on December 15, 1940, local service was begun; express service wasn't begun until 1968, after the Chrystie Street Connection opened.[1]

More branch lines open

On April 9, 1936 the Fulton Street Line opened from Court Street to Rockaway Avenue, along with connecting tracks from Jay Street. The Sixth Avenue Line and Rutgers Street Tunnel opened from East Broadway to Jay Street.[1] [6]

On December 31, 1936, the Queens Boulevard Line was extended from Roosevelt Avenue to Kew Gardens – Union Turnpike. In 1937, service was extended again to 169th Street.[1][9]

On July 1, 1937, the Crosstown Line opened from Nassau Avenue to Bergen Street.[1]

Proposed expansion

Mayor John Hylan proposed some never-built lines in 1922 even before the first leg of the IND was completed. These lines included:[1]

A major expansion of the IND was first planned in 1929.[10] It would have added over 100 miles of new routes in Manhattan, Brooklyn, Queens, and the Bronx, merging with, intersecting or extending the existing IND rights-of way. It was claimed that this expansion, combined with the operating IRT, BMT, and IND lines, would provide subway service within a half mile of anyone's doorstep within these four boroughs.[10] Pricing—excluding acquisition and equipment costs—was estimated at US$438 million; the entire first phase had only cost US$338 million (including acquisition and equipment costs). Not long after these plans were unveiled, the Wall Street Crash of 1929 occurred and the Great Depression was ushered in, and the plans essentially became history overnight.[10] Various forms of the expansion resurfaced in 1939,[1] 1940,[11] 1951,[12] 1968,[13][14] and 1998[15] but were never realized. This was the time when the IND had planned widespread elevated construction.[1]

The Second Avenue Subway, one of the main parts of the plan, is under construction as of 2014.[16]

Timeline

In the 1950s, the IND was extended over two pieces of elevated line that were disconnected from the original BMT system: the BMT Culver Line in 1954, and the Liberty Avenue extension of the BMT Fulton Street Line in 1956.[1]

Line planning

Many IND lines were designed to be parallel to existing IRT and BMT subway lines.

Additionally, some never-built lines were also to serve this purpose.

Extensions after 1940

The following extra extensions and connections were built after unification in 1940:

The following extension is under construction:

Service letters

As originally designed, the IND train identification scheme was based on three things: the Manhattan trunk line served (8th Avenue or 6th Avenue), the northern branch line served (Washington Heights, Grand Concourse/Bronx, or Queens Boulevard), and the service level (Express or Local). The 8th Avenue routes were A, C, and E, while the 6th Avenue routes were B, D, and F. A and B served Washington Heights, C and D served the Grand Concourse, and E and F served Queens Boulevard (via the 53rd Street Tunnel). A single letter indicated express service, and a double letter indicated local service. In addition, G was used for Brooklyn-Queens "Crosstown" service, and H was used for any service on the extended Fulton Street (Brooklyn) line that did not originate in Manhattan.[17]

The first designations were as follows:

AAAEighth Avenue – Washington Heights
BBSixth Avenue – Washington Heights
CCCEighth Avenue – Concourse
D Sixth Avenue – Concourse
E Eighth Avenue – Queens Boulevard
F Sixth Avenue – Queens Boulevard
GGGBrooklyn-Queens Crosstown
HHFulton Street
S Special

Virtually all possibilities were used at one time or another, either in regular service or as brief special routes.[1] The "G" single-letter service was used for G service to World's Fair Station in 1939.

The final pre-Chrystie Street Connection service is shown here; for more details, see the individual service pages. Terminals shown are the furthest the service reached.[17]

After the Chrystie Street Connection opened, the original IND Service Letter scheme was gradually abandoned. All lines, whether local or express, now use a single letter, and only the 8th Avenue/6th Avenue distinction (A, C, E vs. B, D, F) has been maintained.[1]

Platform lengths

The IND was built with longer platforms than those of the IRT or BMT. Initial plans called for stations to be built with 660 feet (200 m) long platforms to accommodate trains of eleven 60 feet (18 m) cars. However, these lengths were shortened, as stations on the IND Eighth Avenue Line between 72nd Street and 163rd Street – Amsterdam Avenue have lengths of exactly 600 feet (180 m). There were two exceptions: 96th Street was 615 feet (187 m) on both levels, as that was the standard length of platforms built for the IND after the 1940s. The 81st Street – Museum of Natural History station had an uptown platform that was 630 feet (190 m) long, and a downtown platform that was 615 feet (187 m). Platforms of exactly 600 feet (180 m) length can also be found on the IND Queens Boulevard Line between Elmhurst Avenue and 67th Avenue.[1]

Some of the IND Sixth Avenue Line stations, on the other hand, have much greater platform lengths. In 34th Street – Herald Square, the uptown platform was originally 745 feet (227 m) (long enough to hold a 12-car train of 60 feet (18 m) cars), and the downtown platform was originally 685 feet (209 m). Both platforms of the 23rd Street station are 670 feet (200 m), and 47th–50th Streets – Rockefeller Center has platforms that are 665 feet (203 m).[1]

In the IND Second System, planned stations would have been 700 feet (210 m) to 720 feet (220 m) long and tile work would have been more "modern".[1]
