Sound Transit changes service twice a year, in March and September. Each fall Sound Transit publishes an annual service plan for public feedback and Board approval. The resulting plan informs the next two service changes before the cycle starts again.
There are two categories of service changes, major and minor, that require different levels of approval and outreach before we can implement them. For more details, see the full 2019 Service Implementation Plan.

Link and Tacoma Link
NEW! Link line colors
To improve clarify as our system expands, Sound Transit is changing to a color system for naming Link light rail lines.
- Link trains from Angle Lake to the University of Washington are now the Red Line. In 2021, the Red Line will open three new stations at Northgate, Roosevelt and the U District.
- Tacoma Link trains are now the Orange Line. In 2022, the Orange Line will open six new stations in the Stadium and Hilltop neighborhoods.
- In 2023, Sound Transit will open the Blue Line, with 10 new stations in Overlake, Bellevue, Mercer Island and Judkins Park. Trains will then share tracks with the Red Line serving all stations from downtown Seattle to Northgate.
