The Dual Contracts, signed on March 19, 1913, and also known as the Dual Subway System, were contracts for the construction and/or rehabilitation and operation of rapid transit lines in the City of New York. The majority of the lines of the present-day New York City Subway were built or reconstructed under these contracts. The contracts were "dual," in that they were signed between the City and two separate private companies (the Interborough Rapid Transit Company and the Brooklyn Rapid Transit Company) who all worked together to make the construction of the Dual Contracts possible.
