The Long Island Rail Road was established in 1834. It is the oldest continually-operating railroad in the United States, still functioning under its original name and charter. It is unique among U.S. railroads in that it operates 7 days a week, 24 hours a day, and 365 days per year. The LIRR has 124 stations, more than 700 miles of tracks, and gives an estimated 335,000 rides per weekday to commuters. Pennsylvania (Penn) Station is its western terminus in Manhattan. Expansion into Grand Central Station is planned for 2019. The Montauk Line train is historically known as "The Cannonball" and has operated continuously since 1899.
