The southern terminus is in San Jose at the 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 express, limited, and local services. There are 28 regular stops, one limited-service weekday-only stop (College Park), one weekend-only stop (Broadway), and one stop that is only served on football game days (Stanford). While average weekday ridership in 2019 exceeded 63,000, impacts of the COVID-19 pandemic have been significant: in August 2025, Caltrain had an average weekday ridership of 39,985 passengers.
Caltrain is governed by the Peninsula Corridor Joint Powers Board (PCJPB) which consists of transit 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).
