 Construction on this line started in the fall of 1885, when ground was broken at the corner of Fulton Street and Red Hook Lane.It was extended east to Albany Avenue on May 30, 1888; Albany Avenue was an eastbound-only station, and the westbound station just beyond at Sumner Avenue had yet to be completed, so it temporarily served both directions.The line was further extended to Ralph Avenue on September 20, 1888.
