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.
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.
For the first time, the Caltrain Traction Power Substation in South San Francisco, constructed by Balfour Beatty and its industry partners, was energized with power from Pacific Gas and Electric Company (PG&E).
California Transportation Commission has approved the funding allocation for one Stadler battery-equipped electric train and related maintenance, charging facility upgrades to help with the transition to fully electrified service and expand zero emission service to non-electrified tracks.
The electrification of Caltrain has reached another major milestone as electric trains operated under power from the overhead contact system (OCS) for the first time.
