The initial segment of the IRT White Plains Road Line opened on November 26, 1904 between East 180th Street and Jackson Avenue. Initially, trains on the line were served by elevated trains from the IRT Second Avenue Line and the IRT Third Avenue Line, with a connection running from the Third Avenue local tracks at Third Avenue and 149th Street to Westchester Avenue and Eagle Avenue. Once the connection to the IRT Lenox Avenue Line opened on July 10, 1905, trains from the newly opened IRT subway ran via the line. Elevated service via this connection was resumed on October 1, 1907 when Second Avenue locals were extended to Freeman Street during rush hours.
