A press release from Sound Transit.
Sound Transit riders will see significant changes in service in the coming weeks, starting on September 19.
In addition to service changes, riders will see changes in the way that Sound Transit lines are named. Link becomes the 1 Line, Tacoma Link becomes the T Line, Sounder South becomes the S Line and Sounder North becomes the N Line.
The opening of the Northgate Link extension on October 2 will add three new stations in North Seattle, including Northgate, Roosevelt and U District. As a result of the opening, southbound ST Express buses on routes 511, 512, and 513 will now end at Northgate station. ST Express route 522 will now end at Roosevelt Station. ST Express routes 542 and 556 will end at the U District Station. Riders on these routes can then transfer to the 1 Line to reach their final destination.
September service changes
Changes to Sounder and ST Express bus routes operated by Pierce Transit will be implemented on Sunday, Sept 19 and Monday, Sept. 20. These include the addition of a roundtrip on the S Line. Train 1507 (2:35 p.m. from Seattle to Tacoma) and its corresponding reverse train (1520, 4:06 p.m. from Tacoma to Seattle) will be restored on Sept. 20, 2021.
In addition, ST Express routes 580 and 596 will each have a trip added to coincide with the restoration of S Line Train 1507. ST Express route 578 will add a late evening weekend departure from Seattle. Other ST Express routes will have minor adjustments to travel times.
