More testing on Sound Transit’s 1 line service between Lynnwood and Seattle will bring an extra train along for the ride on Monday and Tuesday. These tests are in preparation for the upcoming connection to Sound Transit’s 2 line service, once it officially crosses Lake Washington and joins Seattle’s 1 line connector.
On Dec. 1 and 2, from 2:30 to 7:30 p.m., Sound Transit will add test trains in between regular service trains. Test trains will display “Out of Service” destination signs.
Test trains are scheduled 4 minutes after an in-service train. Test trains will run between Lynnwood City Center and Chinatown-International District (CID) 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, which is normal during peak hours.
