Caltrain (reporting mark JPBX) is a California commuter rail line on the San Francisco Peninsula and in the Santa Clara Valley (Silicon Valley). The north end of the line is San Francisco, at 4th and King streets; its south end is Gilroy. Trains leave San Francisco and San Jose about hourly on weekdays, or more frequently during commute hours and for special events (such as sporting events). Service between San Jose and Gilroy is limited to three weekday commute-hour round trips. Weekday ridership in February 2013 averaged 47,060, up 11.1% from February 2012, with ridership at Baby Bullet stations making up 83.5% of total boardings.[1]
Caltrain is governed by the Peninsula Corridor Joint Powers Board (PCJPB), which consists of agencies from the three Caltrain counties. Each member agency has three representatives on 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
