1 Line trains will run test operations during regular service on Friday, June 13 from 5 AM to 9 AM. Please check train head signs before boarding.

Test trains will run between Lynnwood and Stadium on 4-minute headways in both directions alongside regular service. Trains with "Out of Service" head signs will briefly pause at stations but doors will remain closed. This testing will help us prepare for more frequent service once the 2 Line crosses Lake Washington and extends to Lynnwood City Center.

During the testing hours, we will not display estimated train arrival times on the overhead digital signs.
