Wantagh Railroad Complex (also known as the Wantagh Museum), is a collection of old buildings in Wantagh, New York. It consists of the 1885-built Wantagh Railroad Station before it was moved from its original location in 1966, when the Babylon Branch was being elevated throughout the mid-20th century. The station itself was a replacement for original South Side Railroad of Long Island station built in 1867. It also includes a diamond-shaped pre-crossbuck railroad crossing sign, and an old grade crossing gate.
