The Locust Valley station was opened on April 19, 1869, and it served as the terminus of the line until 1889, upon the line's extension to Oyster Bay.[3] On August 22, the turntable and engine house were moved from Glen Street and installed here.[3] Charles Hallet finished a depot here in November 1872; it was photographed by Brainerd in 1878.[4]
The station was rebuilt in November 1872, remodeled in 1885, and again rebuilt in December 1906, when the second station was moved to a private location.[3][5][6][7] The current station building was erected in 1909.[3] The station also contains an old-style wooden shelter on the eastbound tracks, and a former interlocking tower. This former tower, known as LOCUST Tower, now serves as a Nassau County Police Department booth for the Second Precinct's patrolmen assigned to the area.[3]
Station layout
This station has two high-level side platforms, each four cars long. A siding just west of the station served the Nassau-Suffolk Lumber until the late 1970s. The Oyster Bay Branch becomes a single track line a few hundred feet beyond the Birch Hill Road crossing at LOCUST interlocking. No bus access is available at the station.
