Speonk station was originally built in February 1870 along what was then the Sag Harbor Branch.
From 1895–1897 it was known as "Remsenburg station", acknowledging the hamlet of Remsenburg, New York, which lies just south of Speonk.
The station was struck by lightning and burned on June 22, 1901, and a second depot opened in December 1901.
Railroad conductors frequently accentuated the name when calling it out as the next station.
This latter agency and depot were closed in 1958, and the station has been unmanned ever since.
The former station was converted into a snack bar that is still operating as the Trackside Cafe restaurant.

When Eastport and East Moriches stations were closed by the LIRR on October 6, 1958, due to lack of usage, commuters were told to transfer either to this station or to Center Moriches station.
The elimination of the latter on March 16, 1998, makes this the next choice for commuters east of Mastic–Shirley station, almost ten miles away by road.
The traffic from all three intervening stations which have been eliminated since 1950 has been transferred to these two stations.
The former station house and current cafe, is across the tracks from the yard and the platforms have been torn out.
A tough fence was constructed to keep anyone with an attempt of entering the track area out.
the yard features a wye to turn locomotives around.
The first parking lot is south of the platform.
The second large parking lot is across Phillips Avenue.
on weekdays these lots become full of commuters coming in and out of the terminals in New York.

As part of its program to upgrade all stations to high-level platforms, the LIRR relocated the functional portion of Speonk station between 1996 and 1997.
A new platform was built on the west side of North Phillips Avenue (the aforementioned station house is on the east side), along with a new parking lot.
The new platform includes an outdoor enclosure, but no new station building was constructed.
The new station includes ticket vending machines and elegant lighting in the parking lots.
