Sound Transit plans to build an operations and maintenance facility to service Sounder commuter trains. This project is part of the ST2 system expansion plan approved by voters in 2008 to accommodate existing and future ridership growth.

Sound Transit proposes constructing a new, approximately 40,000 square-foot railroad storage facility on the Sounder Rail Yard site between Steilacoom Boulevard SW and 100th Street SW in the City of Lakewood. Additional right of way will be required for the project.

The single-story building would contain maintenance bays, material storage areas, offices and facilities for employees. Supporting facilities such as roadway, site lighting, drainage facilities, and required utility infrastructure are included in the project.
