CEMOF Modifications

What is CEMOF and how is it being modified?

The Central Equipment & Maintenance Facility (CEMOF) serves as the heart of Caltrain where engineers and other Caltrain staff inspect, carry out maintenance and store spare parts for the trains. Originally completed in 2007, the CEMOF building will be undergoing modifications and will be upgraded to prepare for the new electric fleet.

Project Updates

Construction on the CEMOF modifications began in August 2019 and is expected to last into mid-2020. Concrete trucks will be used for construction activities and will access the site from Stockton Street and Lenzen Avenue. Excavated dirt will be stored on-site and sheet pile installation will be used to support the excavation during construction. A new permanent sprung structure will be constructed in the current CEMOF parking lot which will be used to store parts for the new electric trains. Sprung structures are strong, fabric-walled buildings used for industrial purposes that can be quickly constructed and are cost-effective. Construction crew work hours will typically be on weekdays from 7:00 a.m. to 5:00 p.m.
