Sound Transit announces September 2022 Service Change

Changes include addition of two new trips on Sounder S Line and reductions on some ST Express routes


Service changes for Sound Transit service will take effect starting September 17. The changes include additional reductions as well as extending reductions that were implemented at the end of 2021 on certain ST Express routes due to operator shortages. The reductions will affect frequency of service on weekdays.

In the fall of 2021, the Sound Transit Board of Directors approved service increases through the agency’s 2022 Service Plan, but changing effects of the pandemic and broad employment trends have since resulted in nationwide transit operator shortages, requiring long-term trip cancellations and reductions on some ST Express routes. Sound Transit continues to monitor the situation and work with our operating partners to understand the scope and duration of these shortages.

The service change dates are as follows:

  • Saturday, September 17, King County Metro-operated ST Express

  • Sunday, September 18, Community Transit-operated and Pierce Transit-operated ST Express

  • Monday, September 19, Sounder

Changes on Sounder service

The September service change will include two new trips on the Sounder S Line, reinstating the Sounder’s S-Line late-morning northbound trip (departing at 10:06 a.m. from Lakewood) and adding another morning southbound trip (departing at 7:55 a.m. from Seattle).

Due to staffing issues at Amtrak, which is responsible for the maintenance of Sounder cars, the number of car sets on Sounder will be reduced from seven to five until March 2023. The most noticeable impact to S-Line passengers is that they may have to move up the platform to board the train. Additional information about the change is available on our website.

There are no changes to N Line service.
