Originally a streetcar line, it is now the B65 bus route, operated by the New York City Transit Authority.

The eastbound route runs down Boerum Place and makes a left at Atlantic Avenue.

The westbound B65 starts at St Johns Place and runs down St Johns Place for one block and makes a right turn on Buffalo Avenue and runs down Buffalo Avenue until Bergen Street, where it makes a left turn on Bergen Street.

[8] 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.

[13] 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.

In the 1990s, the B65 was rerouted from Cobble Hill north to Downtown Brooklyn, terminating at the Fulton Mall.
