The IND Second System was a plan for a major expansion of the city-owned Independent Subway System in New York, New York. Very little of it was built, though pieces were sometimes built for future expansion on lines that intersect the proposals. Its most famous line, the Second Avenue Line (and its southern extension, originally called the Water Street, New Bowery and Chrystie Street Line), is still being planned, and a short part opened in 1967 as the Chrystie Street Connection.
The first plan was made on September 15, 1929, and is detailed in the table below. Cost is only for construction, and doesn't include land acqusition or other items.

The INDSecondSystem describes a planned but unbuilt major addition to the Independent Subway System of the New York Subway.
The Brooklyn-Queens Crosstown Subway is the only major line in the INDsystem that is almost entirely a two-tracked subway and only the second such line in the entire system like this (The 14th St.-Eastern District (Canarsie) Local (L) is the only other line of this type.
Proposed for the SecondSystem, it was to compete with the 2nd and 3rd Avenue elevated trains.
In June, 1940, the transportation assets of the former BMT and IRTsystems were taken over the City of New York and operated by the City's Board of Transportation, which already operated the INDsystem.
The entire original INDsystem, as built, was entirely underground in the four boroughs that it served, with the exception of a section of track containing two stations spanning the Gowanus Canal in the Red Hook/South Brooklyn section of Brooklyn.
First of all, the subway system began at a time when Thomas Edison and his opponents in the electricity industry were trying to decide whether or to accept alternating current or, as Edison wanted, direct current as the standard way to deliver electricity.
