March 2023 service changes begin to take effect this weekend

Changes include all-day service on ST Express Route 512

Publish Date

Sound Transit regularly reviews our bus and rail service to make changes to improve performance, respond to ridership trends and make the most of the agency’s resources. Starting this weekend, Sound Transit is introducing several service changes, including changes on two ST Express routes that will make a significant difference to riders.

The agency is replacing ST Express 511, which travels between Ash Way and Northgate, with all-day ST Express 512 service between Everett Station and Northgate Station. This will offer riders more transfer opportunities to the 1 Line during peak hours.

The other significant change will be to ST Express 586, which travels from Tacoma to the University District. Riders should be aware that at Federal Way Transit Center buses will now use Bay 2 when traveling northbound. 

Sounder service will have some changes as well. Sounder S Line will receive schedule adjustments to trains #1505 (7:55 a.m., Seattle Departure) and #1518 (10:11 a.m., Lakewood Departure).

Now that Amtrak has restored two Cascades Trains, Sounder N Line passengers will have more options at Everett, Edmonds and Seattle through the Rail Plus program.

The service change dates are as follows:

  • Saturday, March 18, King County Metro-operated ST Express
  • Sunday, March 19, Community Transit-operated and Pierce Transit-operated ST Express.
  • Monday, March 20, Sounder 

There are no changes to Link or Tacoma Link service. 

A full list of service changes is available on the service change page of the Sound Transit website
