Caltrain, Balfour Beatty and PG&E Celebrate Major Milestone of 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 milestone achievement in the Caltrain Electrification Project signifies major progress in expanding Caltrain’s ability to test electric trains at full speed along the corridor and prepare for electrified revenue service in September 2024.
Caltrain has built two main traction power substations, one in San Jose and the other in South San Francisco. Together, with one switch station and seven parallel stations along the corridor, power substations provide, distribute, and regulate electricity to the overhead wires which will power Caltrain’s new high-performance electric trains.
Caltrain, PG&E and Balfour Beatty’s work to complete the energization was substantial, needing to be safely conducted while maintaining rail service to more than 20,000 customers every weekday who depended on the existing infrastructure.
PG&E infrastructure upgrades include:

PG&E infrastructure upgrades include:
- Constructing two, double-circuit 115 kV transmission connections from the East Grand Substation in South San Francisco and the FMC Substation in San Jose to Caltrain traction power stations in those communities.
- Rebuilding the East Grand and FMC substations that enabled PG&E to support Caltrain’s request for redundant transmission feeds.
- Upgrading three PG&E and two third-party remote end substations.
As crews continue to test electric trains along the corridor, Caltrain is embarking on a public outreach campaign to educate passengers, residents, and businesses about best safety practices along the corridor. The agency has sent out mailers, hosted community meetings and embarked on social media campaigns to remind everyone that all overhead wires on Caltrain property should be assumed to be energized now.

Caltrain’s historic Electrification Project is the first undertaking in North America in a generation in which diesel trains and their infrastructure components are transitioned to an electrified system. Electrification means faster and more frequent service, including doubling the frequency on weekends. The passenger experience will be greatly improved as well with the new trains featuring Wi-Fi, power outlets at every seat, onboard displays with digital trip information, and increased storage capacities.
Electrification will also help meet ambitious regional and state climate action goals by lowering greenhouse gas emissions, improving air quality and relieving traffic congestion. Additionally, electrified service will advance equity as well as sustainability along the corridor by reducing noise and air pollution while increasing access for priority equity communities. It will also set the framework for California’s future High Speed Rail network that will run on the Caltrain corridor.
