Central Islip is a station along the Main Line (Ronkonkoma Branch) of the Long Island Rail Road. It is located on the southwest corner of Suffolk County Road 100 (Suffolk Avenue) and Lowell Avenue in Central Islip, New York. Short-term parking is also available on Suffolk CR 100 across from the intersections between Pineville and Hawthorne Avenues.
Central Islip Station was originally built on November 14, 1873 on the southeast corner of Suffolk County Roads 17 & 100 as a replacement for the former Suffolk Station. It was remodeled in 1916, and again in 1958. On November 16, 1987, it was moved to the corner of Lowell Avenue as part of a major reconstruction project of the line in Ronkonkoma, Central Islip, Brentwood, Deer Park, and Wyandanch. The station was built on the site of a former spur to the Central Islip Psychiatric Center, including the hospital's power plant that was abandoned years before the hospital was closed. Across Lowell Avenue is the site of a Waldbaum's warehouse, that once had a freight spur leading to it.
This station has two high-level side platforms each 12 cars long. The north platform is adjacent to the siding track, while the south platform is adjacent to the main track. The Main Line has two tracks at this location.
