Caltrain (reporting mark JPBX) is a California commuter rail line on the San Francisco Peninsula and in the Santa Clara Valley (Silicon Valley). The northern terminus of the rail line is in San Francisco, at 4th and King streets; its southern terminus is in Gilroy. Trains operate out of San Francisco and San Jose on an approximately hourly basis every weekday, with more frequent service provided during commute hours and for special events (such as sporting events). Service between San Jose and Gilroy is limited to three daily commute-hour round trips. Average weekday ridership in February 2012 was 42,354 persons per day, up 12.1% from February, 2011, and ridership at Baby Bullet stations make up 83.5% of all daily boardings.
Caltrain is governed by the Peninsula Corridor Joint Powers Board (PCJPB), which consists of three member agencies from the three counties in which Caltrain line serves. Each member agency sends three representatives to constitute a nine member Board of Directors. The member agencies are the City and County of San Francisco, SamTrans and the Santa Clara Valley Transportation Authority
Caltrain has 29 regular stops, one football-only stop (Stanford Stadium), and two weekend-only stops (Broadway and Atherton). As of October 2012, Caltrain runs 92 weekday trains (22 Baby Bullet), 36 Saturday (4 Baby Bullet), and 32 Sunday (4 Baby Bullet).
