The Hampton Bays station was originally built along what was then the
Sag Harbor Branch on December 20, 1869 (although some sources claim it was in February 1871) as "Good Ground." It was the terminus of the line until summer 1870, when it was extended to Sag Harbor. The station was renamed "Hampton Bays" in June 1922, but the original name can be found along one of the streets on which it is located. The station burned on November 4, 1873. The second station was opened on January 10, 1874 and closed in 1913, but used as an "express house" for the 3rd depot, which opened in summer 1913. The station house was built in the style typical of stations such as
Manhasset,
Riverhead,
Bay Shore,
Northport, and
Mineola stations, and closed in 1958, but remained a flag stop, then razed sometime around 1964. ==Station layout==
