Caltrain’s electrification project reaches major milestone as EMUs begin on-track testing

1 min read

California’s commuter rail service Caltrain has reached a major milestone in its historic Electrification Project as electric trains are now being operated using power from the overhead contact system for the first time in the operator’s 160-year history.

Initial tests will be conducted between Santa Clara and College Park Stations on the Santa Clara Drill Track. Test runs will expand to the main track, between San Antonio and San Jose Diridon stations this summer.  

“The start of testing for our new electric trains marks an historic moment for our agency, symbolizing tangible progress toward electrification,” said Caltrain executive director Michelle Bouchard. “It signifies a future of improved service, reduced environmental impact and a more reliable experience that will benefit both our riders, and the communities that we serve.” 

“Now that our new trains are running on our own power for the first time, it’s clear that the start of electrified service is just around the corner,” added Caltrain board chair Jeff Gee. “I couldn’t be more excited for our riders to experience the future of Caltrain next fall.” 

Owned and operated by the Peninsula Corridor Joint Powers Board, Caltrain provides rail service from San Francisco to San Jose, with commute service to Gilroy. Serving the region since 1863, Caltrain is the oldest continually operating rail system west of the Mississippi.

Looking to the future, Caltrain, as part of its historic Electrification Project, is set to electrify the corridor by 2024, reducing diesel emissions and adding more service to more stations while advancing the agency’s equity goals. 

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 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 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.
