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.
