It is served by both Amtrak Northeast Regional intercity trains and CT Rail Shore Line East commuter service.

Unlike the two-track commuter-rail-only stations on the 50.7-mile (81.6 km)[5] stretch of the Northeast Corridor between New Haven and New London, there are three tracks at Old Saybrook, in order to handle terminal trains on Shore Line East.

In July 2014, the town received a $999,900 state grant to add sidewalks to North Main Street to improve pedestrian access to the station.

After a deal was brokered for the temporary use of handicapped spaces belonging to the Saybrook Station development, the 199-space lot opened on February 4, 2016.
