Welcome

Thank you for visiting the online open house for the Operations and Maintenance Facility (OMF) South project.

To have a congestion-free regional light rail system, Sound Transit needs a place to clean, store and maintain trains. We want your feedback on potential sites for our OMF South, scheduled to open by 2026. 

What is an Operations and Maintenance Facility (OMF)?

An OMF is where trains go for cleaning, storage and maintenance, and operates 24 hours a day, 365 days a year. One OMF currently exists in Seattle, and another facility is under construction in Bellevue. To accommodate additional vehicles for the future 116-mile, voter-approved regional light rail system, the system requires an additional OMF in the South Sound and one in Sound Transit's North Corridor.
