The South Brooklyn and Bergen Street Railroad was organized under the general railroad law and opened by 1865 from Hamilton Ferry along Sackett Street, Hoyt Street, and Bergen Street to Classon Avenue. The Bergen Street Railroad was merged into the Brooklyn and Canarsie Railroad, and on September 21, 1866 an extension to Canarsie Landing along Bergen Street, Nostrand Avenue, Clove Road, Little Lane, and Canarsie's main street"Legal Notices", Brooklyn Daily Eagle, August 8, 1868, page 4 was opened. It was the second line to Canarsie, arriving a year after the Brooklyn and Rockaway Beach Railroad, and was a failure, being foreclosed on January 13, 1868. The original portion, west of the stables at Bergen Street and Classon Avenue, was sold on February 14, 1868; the rest was sold on September 15, 1868. None of the extension to Canarsie was ever used again. The South Brooklyn and Park Railroad acquired the line to Classon Avenue on June 1, 1870, and was again sold on June 19, 1877 as the South Brooklyn Central Railroad. It was authorized in 1878 to build a branch in Bergen Street from Hoyt Street west to Court Street, use the Brooklyn City Railroad trackage in Court Street, and use the Atlantic Avenue Railroad trackage in Atlantic Avenue and Furman Street to the Wall Street Ferry at Montague Street. The Atlantic Avenue Railroad leased the South Brooklyn Central, then extending to Bergen Street and Albany Avenue, on February 2, 1885. The Atlantic Avenue Railroad laid tracks in Boerum Place from Atlantic Avenue south to Bergen Street to connect the lines, as an extension of its Adams Street and Boerum Place Line. The line reached Rochester Avenue by 1897. Eventually the Bergen Street Line cars turned south on Buffalo Avenue, east on the St. Johns Place Line trackage along St. Johns Place and East New York Avenue, and east along Liberty Avenue to City Line. At some point, the west end was truncated to the intersection of Smith Street and Sackett Street. Buses were substituted for streetcars on July 20, 1947, and were replaced again by trolley buses between October 17, 1948 and July 27, 1960. The B65 bus has been truncated more, only running from Cobble Hill east to Ocean Hill; the B12 bus, started by the Brooklyn–Manhattan Transit Corporation as a new route in 1931, later covered Liberty Avenue out to City Line until it was truncated to Broadway Junction in 2010. In the 1990s, the B65 was rerouted from Cobble Hill north to Downtown Brooklyn, terminating at the Fulton Mall.
