Antonin Raymond
Prior to the establishment of passenger service, the site of Great River station was occupied by a freight only station built by the South Side Railroad of Long Island (SSRRLI) known as Youngsport station. Great River Station was originally built in 1897 but burned down in 1943. Between that time, a sheltered-platform was added to the other side of the tracks. In 1945 a modernist station designed by architect Antonin Raymond replaced it, but it was burned down in 2000. The third station with high-level platforms was built in the late 1990s. The original shelter, however was restored by the East Islip Historical Society, and remains within one of the parking lots along the eastbound platform.
