The Nassau Electric Railroad was incorporated in 1893, and its plans included the east-west Church Avenue Line along 39th Street and a branch south along Fifth Avenue into New Utrecht. The Nassau Electric leased the Atlantic Avenue on April 5, 1896, and opened their Fifth Avenue Line that day as an extension of the Atlantic Avenue's line all the way to Fort Hamilton; they also continued to operate West End Line cars via Fifth Avenue, and soon also ran cars to Coney Island over Fifth Avenue and the 86th Street Line.
