Caltrain, Balfour Beatty and PG&E Celebrate Major Milestone of Electrification Project with Energization of Second Traction Power Substation

Energization of transformative undertaking completed this past weekend

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). This milestone achievement in the Caltrain Electrification Project signifies major progress in expanding Caltrain’s ability to test and run electric trains along the corridor.

“Energization of the second traction power substation is a momentous milestone for the Caltrain Electrification Project and continues to keep us on track for launch of Electrified service in fall of 2024,” said Michelle Bouchard, Caltrain Executive Director. “We want to thank the hundreds of people that have been involved in the work and coordination to get us to this moment. Soon we be able to test electric trains along our entire corridor and we are excited to deliver a world-class system for the public.”

“We’re so proud for the opportunity to work with Caltrain in delivering clean, modern, electrified transit service to San Jose, San Francisco and all our hometowns in between,” said Sandra Cullings, Senior Director, PG&E Projects and Construction. “I’m grateful for all the work by my PG&E coworkers who are playing a part in helping Caltrain eliminate diesel emissions, reduce traffic and improve public transit for the Bay Area.”

“We are proud to provide the infrastructure that powers progress on the Caltrain Electrification Project,” said Mark Konchar, Balfour Beatty US Civils President. “This milestone is attributed to the joint efforts of Balfour Beatty, PG&E and Caltrain’s ongoing commitment to collaboration. We look forward to continuing our vital work on the corridor, including the delivery of the Overhead Catenary System, to help our client provide a reliable, safe and sustainable commuter rail service in the area.”

Caltrain’s substation in South San Francisco is also one of two main traction power substations along the Caltrain corridor, in addition to the San Jose location which was energized last August. Together, with eight other smaller facilities along the corridor, power substations provide, distribute, and regulate electricity to the overhead wires which will power Caltrain’s new high-performance electric trains.

As crews continue to install more poles and wire for the electrification system, 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. More safety information about Caltrain Electrification is available here.

The electrification of the Caltrain system will deliver major benefits to the communities that it serves. Electrification will reduce Caltrain’s greenhouse gas emissions and eliminate the particulate matter caused by the aging diesel engines. Engine noise created by the trains will also be reduced.

Service will become both more frequent and more comfortable as state-of-the-art electric trains replace the 30-year-old diesel fleet. Caltrain electrification has also created thousands of jobs locally and throughout the country, both to electrify the corridor and to assemble the new trains, which were debuted to the public in July and are available for a public tour in San Francisco on Saturday, September 23. The infrastructure that is being installed will be compatible with future high-speed rail on the corridor.
