The Staten Island Railway (SIR) is a rapid transit line in the New York City borough of Staten Island. It is owned by the Staten Island Rapid Transit Operating Authority (SIRTOA), a subsidiary of the Metropolitan Transportation Authority, and operated by the New York City Transit Authority Department of Subways. SIR operates 24 hours a day, seven days a week, providing local service between St. George and Tottenville, along the east side of the island. There is currently only one line on the island, and there is no direct rail link between the SIR and the New York City Subway system, but SIR riders do receive a free transfer to New York City Transit bus and subway lines, and the line is included on official New York City Subway maps. Commuters on the railway typically use the Staten Island Ferry to reach Manhattan. The line is accessible from within the Ferry Terminal, and most of its trains are timed to connect with the ferry. In , the system had a ridership of , or about per weekday as of .
The line has a route bullet similar to subway routes: the letters SIR in a blue circle. It is used on timetables, the MTA website, and some signage, but not on trains. Like the New York City Subway, the line runs 24 hours a day every day of the year, and is one of the few 24/7 mass-transit rail systems in the United States. Fares are only collected at two stations, St. George and nearby Tompkinsville.
Although the railway was originally considered a standard rail line, the existing line is severed from the national rail system, and only a small portion of the former North Shore Branch still sees freight use. The passenger operations are now regulated as a rapid transit system, and exempt from certain regulations. The line uses modified R44 subway cars, which are planned to be replaced by R211S cars in January of 2024.
History of the Staten Island Railway
The Staten Island Rail Road was incorporated on August 2, 1851, after Perth Amboy and Staten Island residents petitioned for a Tottenville-to-Stapleton rail line.
