The station has two high-level side platforms, each 10 cars long, serving the outer tracks of the four-track Northeast Corridor.

[1] The Penn Central Transportation Company opened the current station building on March 5, 1970, replacing an older structure, built by the New York & New Haven Railroad, which was demolished.

The station was the centerpiece of Greenwich Plaza, a new mixed-use retail development.

[6][7] A proposed $45 million project, of which plans were shown in July 2019, would replace that building with a new station on the south side of the tracks.
