Caltrain (reporting mark JPBX) is a California commuter rail line serving the San Francisco Peninsula and Santa Clara Valley (Silicon Valley). The southern terminus is in San Jose at Tamien station with weekday rush hour service running as far as Gilroy. The northern terminus of the line is in San Francisco at 4th and King Street. Caltrain has 28 regular stops, one limited-service weekday-only stop (College Park), one weekend-only stop (Broadway), and one football-only stop (Stanford). While average weekday ridership in 2019 exceeded 63,000, impacts of the COVID-19 pandemic have been significant: in August 2022, Caltrain had an average weekday ridership of 18,600 passengers.[1]
Caltrain is governed by the Peninsula Corridor Joint Powers Board (PCJPB) which consists of agencies from the three counties served by Caltrain: Santa Clara, San Francisco, and San Mateo. Each member agency has three representatives on a nine-member Board of Directors. The member agencies are the Santa Clara Valley Transportation Authority, the San Francisco Municipal Transportation Agency, and the San Mateo County Transit District (SamTrans).
Historically served by diesel locomotives, Caltrain is electrifying 51 miles (82 km) of its route between 4th and King and Tamien; diesel trains will remain in service for trains to Gilroy.[6]
