Greenport station opened on July 29, 1844,[2] as the terminus of the Main line of the LIRR, although some in the industry had hope of building an extension to a cross-sound bridge.

[5] On July 4, 1870, it was burned as part of Town festivities, and was rebuilt in October later that year.

Another station was built in its place in 1892 (although some sources claim it was in 1894), with a distinguished ticket office bay window that was removed in the 1920s.

Steam service existed until June 5, 1955,[6] mail was carried at the station until 1965, and the train ran onto a dock until 1978.

[11] This station has one high-level island platform long enough for one and a half cars to receive and discharge passengers.
