  1. Main Line

    The Main Line is a rail line owned and operated by the Long Island Rail Road in the U.S. state of New York. It begins in Long Island City and runs along the middle of Long Island about 95 miles to Greenport. A mile east of Long Island City the four tracks of the East River Tunnels join the two tracks from Long Island City; most Main Line trains use those tunnels rather than running to or from Long Island City. Continuing east, five branches split from the Main Line; in order from west to east, they are: ⁕Port Washington Branch ⁕Hempstead Branch ⁕Oyster Bay Branch ⁕Port Jefferson Branch ⁕Central Branch – a single non-electrified track with no stations, connecting the Main Line to the Montauk Branch Public timetables refer to the Main Line east of Hicksville as the Ronkonkoma Branch. Trains on the Main Line between Long Island City and Ronkonkoma are governed by Automatic Block and Interlocking Signals and by Automatic Train Control. East of Ronkonkoma to Greenport trains operate in non-signalled or "Dark Territory", with all train movements governed by train orders and timetable authority.
