A Growing Puget Sound Rail System for a Growing Region

Link System Development-01

Link Light Rail

Link Light Rail service launched in 2009 with fast, frequent service between Downtown Seattle, the stadiums, the Rainier Valley, and Sea/Tac Airport. In March of 2016 the Puget Sound rail system experienced its first major expansion to the University of Washington and Capitol Hill. This short 3.15 miles of track is expected to add 71,000 daily riders by 2030.

Currently trains run every 6-15 minutes, 20 hours per day, 7 days per week. Free from traffic and with its own right of way, Link’s popularity has exploded since its launch and is projected to carry 350,000 passengers daily by 2030.

As the extensions to Northgate & Angle Lake (2021) and to Lakewood & Bellevue (2023) come online, Link will be the workhorse of our regional transit system.

Sounder Commuter Rail

Sounder Commuter Rail helps take over 14,000 commuters out of traffic during peak hours, providing trains every 20-30 minutes at speeds up to 80mph. Sounder service is offered each weekday on two lines:

The North Line runs 4 daily roundtrips between Everett, Mukilteo, Edmonds, and Downtown Seattle, carrying 2,000 passengers per day.

The South Line runs 7 daily roundtrips between Lakewood and Downtown Seattle. It runs 11 trips from Tacoma, Puyallup, Sumner, Auburn, Kent, Tukwila, and Downtown Seattle, carrying 12,000 passengers per day.

Seattle Streetcar Network

Seattle inaugurated modern streetcar service in 2007 with the South Lake Union line, connecting commuters and residents in South Lake Union with the Westlake transit hub. Now the First Hill line connects the King Street Hub to First Hill and Capitol Hill along Broadway. In the next few years, planned streetcar extensions include a North Broadway extension to the First Hill Line, and connecting the two lines through Downtown Seattle via 1st Avenue.
