1 Line trains are delayed up to 20 minutes until further notice due to signal communication issue.

1 Line trains have resumed regular operations at SeaTac Station. Trains are still delayed due to signal communication issues necessitating that operators use manual procedures when coordinating train movement. These manual procedures take more time and are necessary for safe train operation. There is not yet an estimated time for when trains will return to regular headways. Updates will be provided as they become available. Please plan ahead for additional travel time as we work to adjust train movement to realign with our posted schedule.
