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.

Throughout the mid-20th century, the Long Island Rail Road was reconstructing the Atlantic and Babylon Branches in Queens, Nassau, and Western Suffolk Counties, which required elevating the lines and rebuilding new stations.

It was moved a few blocks north to the site of an old neighborhood amusement park in 1966 and restored through 1969.

In 1972, the LIRR donated the 1912-built parlor car called "The Jamaica" to the museum, which contained a solarium, cooking facilities and an ice-cooled air conditioning system.

In 1982, the station was opened to the public as a museum, and was added to the National Register of Historic Places on June 30, 1983.
