Ronkonkoma (signed asRonkonkoma LI MacArthur Airport) is a majorrailroad station and transportation hub along theMain Line of theLong Island Rail Road inRonkonkoma,Suffolk County,New York. The station is the easternterminus of theRonkonkoma Branch and the western terminus of theGreenport Branch, and it also serves the adjacentLong Island MacArthur Airport. It will eventually also be served byAmtrak'sNortheast Regional.
The station is located on Railroad Avenue North across from the intersection of Hawkins Avenue, and has parking facilities and other amenities that extend beyond the central location. Free parking is available in the lots adjacent to the tracks on the north and south side. Oneparking garage north of the station was built in 1996 on a former freight spur.[4][5] The station has a total of approximately 5,452 parking spaces.[6]

Ronkonkoma Station was originally built asLake Ronkonkoma station in 1883 as a replacement for the 1843-builtLakeland station designed to serve bothLakeland andRonkonkoma, New York, as well as the 1853-builtHermanville station, designed for a former community along the south side of the tracks.[7]
Lakeland was originally built in 1843 asLake Road station. It was named for and located on Lake Road (now Pond Road), a street that once ran fromOakdale to the east side ofLake Ronkonkoma itself. By 1850 it was moved to the Dr. E. F. Peck General Store on the northwest corner of what is today Ocean Avenue and Lakeland Street. A freight house existed along the tracks close to Pine Avenue. Edgar Fenn Peck owned land as far south asSayville, and in 1851 sold the store and the land to a developer named Charles Wood, who turned his land into a development named Lakeland Farms, which today includes land in Oakdale,Bohemia, and what is nowRonkonkoma.[7] The original Lake Road station operated simultaneously with the one at the general store on Ocean Avenue, and at some point was renamed "Lake station," until eventually being phased out. No record of the original station's existence can be found after 1857.[7][8]
Hermanville orHermannville was another station stop along theGreenport Branch of theLong Island Rail Road, located east of the former Lake Road Station. It first appeared on an 1850 map of the Long Island Rail Road.[9] The station had one side platform, and two tracks. An 1852 advertisement for Hermanville in a few books mention the Long Island Rail Road.[10][11] Hermannville also made an appearance on the 1855 Colton map.[12] On the Map of The Village of Hermannville, Town of Islip, Suffolk County, Long Island, Hemannville station is shown as being at the intersection of the Main Line and Herman Avenue, which today is part of the Ronkonkoma Yard.[8][13][14]
Lake Ronkonkoma station replaced Lakeland station in 1883 and was designed to serve bothLakeland andRonkonkoma, New York. At some point, the word "Lake" was dropped from the station name. The station house burned on February 7, 1933 and a temporary rectangular one-story building with a gabled roof was used until September 1937, when the second Ronkonkoma station was completed.[8][15] Throughout much of the 20th century, it also served as a sizable freight hub for central Suffolk County.[8]
Since December 28, 1987, the present Ronkonkoma station has been the east end of the electrified portion of the Main Line, but stations east of Ronkonkoma have been modified to allow for electrification in the future.[8] The 1937 station was used for storage until it was razed in 1994 when part of the station's parking lot was extended westward. The current station was designed by architect Richard Henry Behr.[16][17]
Ronkonkoma Yard is also located east of the station, in close proximity to the formerHolbrook station, which was torn down in 1962.[18] Ronkonkoma station has also served commuters from the formerHoltsville station since its closure in March 1998.[8]
This station is set up using theSpanish solution with three high-level platforms, each 12 cars long. Platform B, anisland platform, facilitates across-platform interchange when a Ronkonkoma Branch train and a Greenport train arrive at the same time on opposite tracks.

In February 2024, theFederal Aviation Administration approved the Town of Islip's plan to erect a new airport terminal on the north side of MacArthur Airport, adjacent to the south side of the Ronkonkoma LIRR station.[19][20][21][22][23] The project will directly connect the Ronkonkoma LIRR station with the new airport terminal via a pedestrian walkway, creating a direct LIRR connection to the airport without needing to transfer to buses or taxis.[19][20][23][24]
In February 2025, New York state announced that it is investing $150 million into the construction of the pedestrian connection between the station and new airport terminal.[21][22][23][24]
In January 2025, Suffolk County Executive Edward Romaine, along withAmtrak officials, officially announced that a new Long Island branch of Amtrak'sNortheast Regional would serve – and terminate at – the Ronkonkoma station, with intermediate stops atJamaica andHicksville east ofPenn Station. It was reported that work was expected to begin in 2026, and that Amtrak service was anticipated to commence in 2028, at the earliest. Trains would operate using diesel on Long Island. Required infrastructure upgrades for the service would likely include an additional platform and track at the station. Suffolk County Executive Ed Romaine said that Amtrak wanted the extension, in part, due to the Ronkonkoma station's location adjacent toLong Island MacArthur Airport.[25]
In January 2025, it was announced by Suffolk County that, in addition to the new Amtrak service at Ronkonkoma, a new passenger bus depot will also be built on the south side the station, primarily servingSuffolk County Transit buses.[25]
TheMid-Suffolk Yard – also known as theRonkonkoma Yard – is a 23-track train storage yard, located just to the east of the Ronkonkoma Long Island Rail Road station.[28] As this is the eastern end of the electrified portion of the Main Line, the yard stores the LIRR'selectric multiple unit train sets that are used on the Ronkonkoma Branch.[28]
In preparation for the LIRR'sEast Side Access expansion toGrand Central Terminal, the MTA added 11 new tracks to the yard, for a total of 23 tracks.[28] The expansion used space already owned by the MTA, located immediately to the south of the existing rail yard and north ofMacArthur Airport. The increase in storage space allowed the MTA to increase peak-hour service to Manhattan. The project was budgeted for $128 million.[29][30][31] Locations in Deer Park, Central Islip, and Yaphank were also considered for the construction of the yard. The Deer Park option was dismissed as it would have impacted several grade crossings, duplicated employee facilities and as it would not have benefited riders east of the station. The Central Islip site was dismissed as it would have been located withinConnetquot River State Park Preserve. The Yaphank option was rejected because of the high cost of electrification, as well as due to the requirement that all stations between Ronkonkoma and Yaphank – namely,Medford andYaphank – receive upgrades.[32]
The construction work was initially expected to be finished by late 2018.[31] Construction was to start in September 2017, with completion being pushed back to March 2020.[33] A construction award was finally made in December 2017, and the completion date was pushed back to late 2020.[34]: 32 The yard was ultimately completed in November 2020.[35]
