The Brooklyn Rapid Transit Company's Fulton Street elevated railroad line above Liberty Avenue opened in 1915, with a station at Lefferts Avenue (now Lefferts Boulevard). The elevated train system only charged a 5-cent fare. The nickel fare was another major factor in the development of Ozone Park, as residents could travel across the entire elevated and subway system for 5 cents. After the opening of the elevated line, real estate developers began buying up all the lots on either side of Liberty Avenue in hopes the new station would attract more people to want to live in Ozone Park.
