The tracks from Flatbush south to Manhattan Beach were removed from 1938 to 1941,[1] while most of the rest is now the freight-only Bay Ridge Branch.

By 1873, the line was to run from Bay Ridge to East New York, where it would join the LIRR's Atlantic Avenue Division to Jamaica.

[7][8] The NY&MB bought the eastern half of Coney Island from the town of Gravesend and renamed it Manhattan Beach.

[9] The NYBR&J built the line from Bay Ridge east to New Lots, while the NY&MB built from Manhattan Beach north to the NYBR&J at Manhattan Beach Junction and from New Lots north to East New York on the west side of the Canarsie Line.

[17][18] The Kings County Central Railroad was incorporated in 1877 by Electus B. Litchfield and Austin Corbin to build a 3 ft (914 mm) narrow gauge line from downtown Brooklyn via the east side of Prospect Park to a connection with the NYBR&J east of Manhattan Beach, and to be leased by the NYBR&J.

Corbin, who owned a summer house near Babylon,[25] put up the money to build the road, which was also planned to cross the South Bay near Amityville to Fire Island.

[26] Corbin acquired a controlling interest in the Long Island Rail Road on November 29, 1880[27] and became president on January 1, 1881.

[37] In 2011, the long abandoned right-of-way of the New York, Brooklyn and Manhattan Beach Railway was subject to legal action by some homeowners living adjacent to its route in Sheepshead Bay, who wanted to acquire undisputed title to it.
