The Long Island Rail Road , legally known as the Long Island Rail Road Company and often abbreviated as the LIRR, is a commuter rail system in southeastern New York, stretching from Manhattan to the eastern tip of Suffolk County on Long Island. With an average weekday ridership of 337,800 passengers in 2014, it is the busiest commuter railroad in North America. It is also one of the few commuter systems in the world that runs 24 hours a day, 7 days a week, year-round. It is publicly owned by the Metropolitan Transportation Authority, as MTA Long Island Rail Road. The current LIRR logo combines the circular MTA logo with the text Long Island Rail Road, and appears on the sides of trains. The LIRR is one of two commuter rail systems owned by the MTA, the other being Metro-North Railroad. Established in 1834 and having operated continuously since then, it is the oldest U.S. railroad still operating under its original name and charter.
