Long Island Rail Road - Passenger Lines and Services

Passenger Lines and Services

The Long Island Rail Road system is made up of eleven passenger branches. Two main trunk lines, the Main Line and Montauk Branches, spin off nine smaller branches. For scheduling and advertising purposes some of these branches are further divided into sections such as the case with the Montauk Branch, which is known as the Babylon Branch service in the electrified portion of the line between Jamaica and Babylon, while the diesel service beyond Babylon to Montauk is referred to as the Montauk Branch service. All branches except the Port Washington Branch pass through Jamaica; the trackage west of Jamaica (except to Port Washington) is known as the City Terminal Zone. The City Terminal Zone includes portions of the Main Line and Atlantic and Montauk Branches as well as the Amtrak-owned East River Tunnels to Penn Station. The passenger lines are:

• The Main Line runs from Long Island City east to Greenport; trains using the Northeast Corridor and the East River Tunnels from New York Penn Station join the line at Sunnyside Yard. It is electrified west of Ronkonkoma; limited diesel train service runs from this point to Yaphank, Riverhead or Greenport. The services that run along this line are named after the branches they use; trains beyond Hicksville (where the Port Jefferson Branch splits), are known as Ronkonkoma Branch and the Greenport Branch trains.

• The Montauk Branch runs from Long Island City to Montauk, meeting the Main Line at Long Island City and Jamaica. It is electrified from Jamaica east to Babylon; only diesel trains use the "Lower Montauk" section west of Jamaica or the outer section east of Babylon. Only trains east of Babylon are considered part of the Montauk Branch service; the line from Lynbrook to Babylon carries Babylon Branch trains.

• The electrified Atlantic Branch runs from Atlantic Terminal in Downtown Brooklyn east to Jamaica, where it meets the Main Line, and then heads southeast to end at the Montauk Branch at Valley Stream. East of Valley Stream, the Far Rockaway Branch turns south, while the West Hempstead Branch turns northward.

• The electrified Port Washington Branch, the only one that does not serve Jamaica, branches from the Main Line west of Woodside, but runs alongside it until Winfield Junction, which is east of that station, and heads east and northeast to Port Washington. It only serves four stations in Nassau County.

• The Port Jefferson Branch branches from the Main Line at Hicksville, with electric service to Huntington and diesel service to Port Jefferson. Until 1938, it continued east to Wading River.

• The electrified Hempstead Branch branches from the Main Line east of Queens Village (does not curve away from Main Line until Floral Park) and runs east to Hempstead. At Garden City, the Garden City-Mitchel Field Secondary curves off and goes to Mitchel Field.

• The electrified West Hempstead Branch branches from the Montauk Branch at Valley Stream and runs northeast to West Hempstead, originally continuing to junction the Hempstead Branch and the Oyster Bay Branch at the Main Line. There is no weekend service on this branch.

• The Oyster Bay Branch splits from the Main Line at Mineola and heads north and east to Oyster Bay. The first section to East Williston is electrified; only diesel trains run along the majority of the line to Oyster Bay.

• The diesel-only Central Branch runs southeast from the Main Line at Bethpage to the Montauk Branch at Babylon, giving an alternate route to the Montauk Branch east of Babylon. The Central Branch used to continue west from Bethpage to include what is now the Garden City–Mitchel Field Secondary.

• The electrified Far Rockaway Branch splits from the Atlantic Branch at Valley Stream and runs south and southwest to Far Rockaway. It used to continue west along what is now the New York City Subway's IND Rockaway Line to Hammels and Rockaway Park.

• The electrified Long Beach Branch splits from the Atlantic Branch at Valley Stream but does not curve away from the Babylon Branch until just after Lynbrook, where it turns south to end at Long Beach.
