Sounder commuter rail (reporting mark SDRX) is a regional rail service operated by BNSF on behalf of Sound Transit. Service operates Monday through Friday during peak hours from Seattle, Washington, north to Everett and south to Lakewood. 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. Two daily round-trips run the "reverse commute" to and from Tacoma. Additional Sounder trains operate on some Saturdays and Sundays for travel to and from Seahawks and Sounders games at CenturyLink Field and Mariners games at Safeco Field. Both stadiums are a short walk from King Street Station.

The South Line began service with two round trip trains on September 18, 2000 with stops in Tacoma, Sumner and Auburn that terminated in Seattle. Puyallup and Kent stations were added February 5, 2001, with Tukwila being added March 12, 2001. There are currently eleven round trips on the South Line, with two operating in the reverse commute direction. Sound Transit plans to add two additional round trips by September 2017.
