This week, Caltrain marked the first anniversary of its fully electrified service today, celebrating a transformative year that has seen record ridership growth and faster, more frequent service throughout the peninsula.

According to an agency release, Caltrain has recorded a surge in ridership since the launch of the electrified service in September 2024.

Over fiscal year 2025, Caltrain carried 9.1 million passengers, up from 6.2 million in FY 2024. Weekend ridership has more than doubled, and July 2025 alone saw ridership increase 78% compared to the same month the year prior, making it the second consecutive month with more than one million riders.

Special event travel has also increased, with monthly San Francisco Giants ridership up by as much as 82% over last year, and Caltrain running popular themed trains for special events since last December. Youth ridership has also quadrupled since the introduction of the $1 Youth Fare, which launched the same month as electrification.  

“Electrification has completely transformed Caltrain,” said Michelle Bouchard, Caltrain executive director. “We’re delivering cleaner, faster, and more frequent service, and riders are responding in record numbers. This first year has shown what’s possible when we invest in sustainable rail, and we’re only just getting started.”

Electrification has allowed Caltrain to expand service while cutting travel times:

• Express trains now travel between San Francisco and San Jose in just one hour.

• Local trains cover the same distance in 75 minutes, 33% faster than diesel service.

• Weekend service has doubled, with trains every 30 minutes.

• Every station on the line is now served by at least one train in each direction every thirty minutes, with 16 stations seeing trains every 20 minutes and 11 stations seeing one every 15 minutes.

These upgrades have expanded system capacity by 30%, providing more options for riders across the peninsula and beyond.

Additional Benefits of Caltrain’s Electric Service

The new fleet also enhanced the onboard experience for Caltrain riders. The new trains offer free Wi-Fi and charging outlets at nearly all seats, all while being cleaner and quieter than ever before.

The transition to electrified service has also produced environmental benefits, according to the release. Caltrain’s electric fleet is returning 23% of its power supply to other trains or the grid, thanks to its new regenerative braking technology. Additionally, the new fleet is even more efficient than projected, costing $3 million less than expected.

Caltrain has been celebrating this milestone for all of Transit Month, with passenger outreach efforts planned at San Francisco, Millbrae, Hillsdale, Redwood City, Palo Alto, Mountain View, Santa Clara, and San Jose Diridon Stations for this week, offering opportunities for riders to receive Caltrain merchandise for speaking of their experiences on Caltrain. 

“Today we celebrate one year of electrified Caltrain — using clean technology to connect more communities and economies throughout our state while laying crucial groundwork for high-speed rail,” said Governor Gavin Newsom, one of many elected officials who celebrated Caltrain’s anniversary. “I’m proud to back projects like this, showcasing California’s leadership in driving innovation in a way that is future-proof and accessible for all.”

The Caltrain Electrification Project also provided a boost to the economy, supporting more than 33,000 jobs across 36 states through design, construction, and supply chain partnerships.
