Deer Park station
railway station in Baywood, the United States of America
Deer Park is a station along the Main Line (Ronkonkoma Branch) of the Long Island Rail Road. It is located at Pineaire Drive, Executive (formerly Grant) Avenue, and Long Island Avenue in Baywood, New York.
History
Deer Park, sometimes mentioned as Deerpark, 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 at 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), served as a replacement for both stations, and was also originally planned also to replace Brentwood Station until public opposition from Brentwood thwarted that proposal. 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.
The station underwent a renovation in 2019 as part of the MTA's Enhanced Station Initiative and the LIRR's Double Track Project. The station received a new ADA-compliant station house, new canopies, new platform shelter, and added platform amenities such as help points and complimentary WiFi. The rebuilt station was designed by Urbahn Architects.
