The station has two side platforms, each ten cars long, which serve the outer tracks of the four-track Northeast Corridor.

The current station building, built about 1894, is a well-preserved example of the New Haven Railroad's period stations, with a utilitarian interior and exterior nods to period Victorian architectural styles.

It was added to the National Register of Historic Places in 1989 as Sound Beach Railroad Station.

[3] The station formerly had six-car-length high-level platforms, which could not serve all cars on some trains.

[4] The scope of the project was later expanded to include platform extensions to 10-car length, as well as an expansion of the south parking lot.
