Deer Park is a station along the Main Line (Ronkonkoma Branch) of the Long Island Rail Road. It is officially located at Pineaire Drive, Executive (formerly Grant) Avenue, and Long Island Avenue near Deer Park, New York. The actual location is in West Brentwood, New York.
Deer Park Station was previously located at the bridge over New York State Route 231, until it was moved as part of a major reconstruction project of the line in Ronkonkoma, Central Islip, Brentwood, Deer Park, and Wyandanch. The original station was built in 1842, then rebuilt in 1884, and again 1936 for the bridge over Deer Park Avenue (NY 231 did not exist at the time). The 1987-built station was built close to the former Pine Aire Station near the Pilgrim State Psychiatric Center(see below) and served as a replacement for both stations. As a result, some people refer to it as "Pine Aire Station" rather than its given name. In the process of reconstruction, a former one-lane bridge was blocked off.
This station has two high-level side platforms each 12 cars long. The north platform, adjacent to Track 1, is generally used by westbound or New York City-bound trains. The south platform, adjacent to Track 2, is generally used by eastbound trains. The Main Line has two tracks at this location.
Pineaire(or Pine Aire) was a station stop along the Ronkonkoma Branch of the Long Island Rail Road in West Brentwood, New York. It was located east of the Pilgrim State Hospital Spur than the currently combined Deer Park-Pineaire complex. In fact it was located on the east side of Sagtikos State Parkway on the opposite side of the intersection of Pine Aire Drive(formerly Edgewood Road) and Manatuck Boulevard.The station first opened around 1915 near the former Thompson's Station across from a freight spur, and was finally closed around October, 1986, when the two stations were being combined into one.
