Sounder commuter rail (reporting mark SDRX) is a commuter rail service operated by BNSF on behalf of Sound Transit.^[4] Service operates Monday through Friday during peak hours from Seattle, Washington, north to Everett and south to Lakewood. In 2023, the system had a ridership of 1,630,000, or about 7,000 per weekday as of the fourth quarter of 2023.

As of 2017^[update], schedules serve the traditional peak commutes, with most trains running inbound to Seattle in the morning and outbound in the afternoon. Three daily round-trips run the reverse commute to and from Tacoma.^[5] Additional Sounder trains operate on some Saturdays and Sundays for travel to and from Seahawks and Sounders games at Lumen Field and Mariners games at T-Mobile Park. Both stadiums are a short walk from King Street Station.
