Orange County Maintenance Facility

The Orange County Transportation Authority (OCTA) has filed a Conditional Use Permit for the development of an approximate 90,000 square foot commuter rail maintenance facility (Orange County Maintenance Facility (OCMF)).  

The OCMF is proposed off of Ridge Valley near Marine Way on a 21.3 acre parcel. 

The proposed facility is where passenger trains will be serviced, cleaned, stored overnight and where train crews will use as a base for shift changes. The proposed project includes a 48-foot tall one-story building that includes locomotive and car service platforms for inspection. Additional on-site services include sanding of train wheels, fueling of the locomotives and sanitation dump stations.  

The proposed site plan also includes a train washing facility. Additional proposed facility components include office space for crews and maintenance staff, parts storage and management, on-site water treatment, parking, access roads, and security.
