Project update

Sumner Sounder

Garage conditional use permit application submitted

Have you seen signs around Sumner Station about a proposed new building? That is the City of Sumner’s public notice for the conditional use permit application for the new Sumner Station parking garage. Keep in mind that the drawings posted on the City’s website are drafts, and designs are still being finalized.


We expect to release updated designs to the community later this summer, along with information about the construction, anticipated to start this fall.

Reminder: new Puyallup Station garage open

Do you worry about finding a parking space at Sumner Station? Consider trying out the new Puyallup Station garage and surface parking, located just three miles away at 505 2nd Avenue NW, Puyallup. The facility, with over 680 new stalls, opened to the public on March 27. Make sure to use the third-floor pedestrian walkway, or the new crosswalk at 2nd Ave., to cross 5th Street, then make your way to the platform from the garage.

Sounder special event trains this summer

Sounder runs special service on select weekends for some sporting events, conventions and celebrations. Upcoming game trains include:

  • July 2: Mariners vs. Tampa Bay Rays.
  • July 10: MLB Home Run Derby.
  • July 11: MLB All-Star Game.
  • July 16: Mariners vs Detroit Tigers.
  • July 23: Mariners vs Toronto Blue Jays.

And remember, you don’t have to go to the game to use a special event train. Take advantage of the weekend Sounder trips to explore Seattle or other communities on the S Line. Read more in our blog post.

A new future for Sounder South?

With changes in travel patterns, we have the opportunity to reimagine Sounder South: Should we pivot from a service that primarily serves peak commuter travel (north to Seattle weekday mornings and south weekday afternoons) to one that accommodates different travel needs and types of trips?


Sound Transit will update the Sounder South Strategic Plan this year to consider whether potential additional trips should be prioritized over longer trains. Longer trains would help us carry more people during the busiest times, while more trips could help us provide service during different times of day or week.


Any new trips require approval and negotiation with BNSF Railway, which owns most of the tracks Sounder runs on.
