On Dec. 8 and 9, from 4:30 to 9:30 a.m., Sound Transit will add test trains in between regular service trains. Test trains will display “Out of Service” destination signs.

Expect test trains 4 minutes after an in-service train.

Test trains will run between Lynnwood City Center and International District/Chinatown stations. Those trains will pause at stations, but doors will remain closed. Please check train head signs before boarding.

Regular service trains will arrive at stations every 8 minutes during the testing period.

This testing is in preparation for increased service after the 2 Line crosses Lake Washington and extends to Lynnwood City Center.
