Mattituck is a simple station stop on the Greenport Line. It consists of a single modern high-level platform built in about 1999 that can only fit a car and a half. This modern platform is located just east of the grade-crossing of Westphalia Avenue in the village center of Mattituck. It has a single staircase and a ramp up to it from a parking lot with about 20 spaces, along Pike Street. This parking lot extends east of the platform a short ways to the next grade crossing of Love Lane. The platform has the usual green railings and a small waiting area enclosed by windscreens with brown and cream framework that have a small canopy extending over a tiny portion of the platform.
