Operations and Maintenance Facility: East

Project Highlights


  • Link light rail

Start of service:



Sound Transit is building an Operations & Maintenance Facility in Bellevue that is needed for the expansion of the region's light rail system. By 2023, the system will grow from 16 to 50 miles and the existing light rail fleet will triple in size from 62 to 180 184 vehicles. The current operations and maintenance facility in Seattle, which can store and maintain up to 104 light rail vehicles, will reach full capacity in 2020. The new facility will be designed to maintain, store and deploy 96 vehicles and support the efficient light rail operations approved by voters in 2008 as well as the Federal Way and Redmond Link Extensions. To meet these needs Sound Transit’s new facility must be near an operating light rail line, roughly rectangular in shape and up to 25 acres.



  • Final Design


Budget: $449.2M

Milestone: In July 2014, after a 45-day Draft EIS public review and comment period, the Sound Transit Board identified the BNSF site as the preferred alternative for the new operations and maintenance facility.

The OMFE will:

  • Accommodate expansion of the Link light rail system to Lynnwood Transit Center, Bellevue/Overlake and Kent/Des Moines
  • Provide efficient and reliable light rail service and minimize system operating costs
  • Support Sound Transit's Regional Transit Long-Range Plan, the adopted Puget Sound Regional Council's VISION 2040 and Transportation 2040 plans.


  • East King County
