List of New York City Subway stations in Manhattan

The WS&YP went bankrupt in 1871 and was replaced by the New York Elevated Railroad, which would later build the IRT Third Avenue Line.

The Third Avenue El originally terminated at Grand Central Depot, until it was expanded uptown, transforming the segment into a spur.

Meanwhile, the Gilbert El was reorganized as the Metropolitan Elevated Railway and was permitted to build the IRT Second Avenue Line in 1875.

The subway was only located in the vicinity of the Rogers Peet Building along Broadway between Warren and Murray Streets.

With no support for the system from Mayor William Tweed, the line had limited use and ran only between 1870 and 1873 before being abandoned and sealed.

In the 1910s and 1920s, the Dual Contracts brought expansion and improvements on subways and els for both the IRT and BRT in four of the five boroughs of the city.

Also during the 1920s, New York City Mayor John Hylan was planning a new city-owned "Independent" Subway System to compete with the IRT and BRT, later BMT.

Eventually, some growing disdain for the noise of the els, and the fact that the subways were rendering them obsolete lead to their closure.

The Ninth Avenue el closed in 1940, except for the segment northeast of 155th Street when it became the southern terminus of the Polo Grounds Shuttle until 1958.

The first phase of the IND Second Avenue Line, which was planned as far back as 1919, opened in 2017, with provisions for future expansion south to Hanover Square and north to 125th Street.
