[1] The CIFH&B was chartered by the New York State Legislature on June 7, 1890, to build from the 39th Street Ferry through New Utrecht to Coney Island and Fort Hamilton.
Flynn's plan was to build the Union Street Line and a connection along Second Avenue to the CIFH&B, allowing the RIFH&B to reach Hamilton Ferry.
[7] Flynn then incorporated the Nassau Electric Railroad on March 13, 1893, in order to raise more capital for the system[8] and with the right to use the tracks of the other three companies.
[9] In the next few years, most of the system's franchised lines, totalling about 100 miles (160 km), were built:[10] Flynn incorporated the East River and Atlantic Ocean Railroad on November 16, 1895, to gain access to the Brooklyn Bridge, Long Island City, and other places.
[11] However, the Nassau leased the Atlantic Avenue Railroad on April 4, 1896, thus gaining Fifth Avenue and other streets north to the bridge, a lease on the Brooklyn, Bath and West End Railroad (West End Line), and several other lines,[12] and the ER&A was no longer necessary.
