The Long Island Rail Road (reporting markLI), or LIRR, is a railroad in the southeastern part of the U.S. state of New York, stretching from Manhattan to the eastern tip of Suffolk County on Long Island. The railroad currently operates a public commuter rail service, with its freight operations contracted to the New York and Atlantic Railway. With an average weekday ridership of 354,800 passengers in 2016, it is the busiest commuter railroad in North America.[4][5] It is also one of the world's few commuter systems that runs 24/7 year-round.[6] It is publicly owned by the Metropolitan Transportation Authority, which refers to it as MTA Long Island Rail Road. In 2023, the system had a ridership of 75,186,900, or about 276,800 per weekday as of the second quarter of 2024.
The 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 the Metro-North Railroad in the northern suburbs of the New York area. Established in 1834 (the first section between the Brooklyn waterfront and Jamaica opened on April 18, 1836) and having operated continuously since then, it is the oldest railroad in the United States still operating under its original name and charter.[7][8][9]
There are 126 stations and more than 700 miles (1,100 km) of track[9] on its two main lines running the full length of the island and eight major branches, with the passenger railroad system totaling 319 route miles (513 km).[10] As of 2018[update], the LIRR's budget for expenditures was $1.6 billion plus $450 million for debt service, which it supports through the collection of fares (which cover 43% of total expenses) along with dedicated taxes and other MTA revenue.[11][12]
^Brennan, Jim. "LIRR's Heavy Subsidies and the Coming Debate Over MTA Funding", Gotham Gazette, January 10, 2019. Accessed March 9, 2022. "The data show the LIRR farebox will contribute 43.4% of the LIRR's operating costs in 2019 and declines to about 38% by 2022.... This analysis shows that the Long Island Rail Road's deficit is $1.345 billion a year and is more than 18% of the MTA's total deficit, although its fare and other operating revenue provide about 12% of the MTA's total revenue."
