Caltrain, operating in California's Bay Area, is a key player in sustainable regional mobility, linking San Francisco, Silicon Valley, and San Jose through a 77-mile electrified rail corridor. Beyond commuter service, Caltrain supports urban development, regional logistics, and tech-sector workforce mobility. Its infrastructure features real-time data systems, electrified rolling stock, and automated control technologies, aligning with California's decarbonization goals. Caltrain's investment in high-efficiency rail systems, passenger analytics, and eco-friendly practices underscores its commitment to transforming public transit into a model of smart transportation and urban resilience.
Currently, Caltrain returns approximately 23% of the power it uses back to the power grid, providing power to residents and businesses along its corridor.
Caltrain, which currently shares a headquarters with SamTrans in San Carlos, will continue to co-locate with SamTrans at their new headquarters at Gateway at Millbrae Station.
This marks the final corridor-wide test before the launch of electrified service in September, as well as the last weekend service change for the Electrification project.
Caltrain, with its partners Pacific Gas and Electric Company (PG&E) and Balfour Beatty, has successfully energized and tested the full 51-mile Caltrain-owned corridor between San Francisco and San Jose.
This 1,000-mile testing process is required to ensure all safety and quality standards are met in order to ensure that the trains can safely operate on Caltrain’s tracks.
