context_page_description: Caltrain is a California commuter rail line on the San Francisco Peninsula and in the Santa Clara Valley. The northern terminus of the line is in San Francisco at 4th and King Streets; its southern terminus is in San Jose at Diridon Station with rush hour service running as far as Gilroy. Trains leave San Francisco and San Jose hourly during weekdays, and every 90 minutes during weekends, with limited stop service during rush hour running every 20 minutes, and "Baby Bullet" express service running every 30 minutes. Extra trains are often run for special events held in Oracle Park in San Francisco, Stanford Stadium in Palo Alto, and SAP Center in San Jose. Caltrain operates 92 weekday trains, six of which extend to Gilroy. Weekday ridership in February 2018 averaged 65,095.
  Caltrain is governed by the Peninsula Corridor Joint Powers Board which consists of agencies from the three counties served by Caltrain: San Francisco, San Mateo and Santa Clara. 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.
context_section_description: In June 2004, Caltrain finished its two-year CTX (Caltrain Express) project for a new express service called the Baby Bullet. The project entailed new bypass tracks in Brisbane and Sunnyvale as well as a new centralized traffic control system. The Baby Bullet trains reduced travel time by stopping at only four or five stations between San Francisco and San Jose Diridon Station; the express trains could overtake local trains at the two locations (near Bayshore and Lawrence stations) where bypass tracks were added. Travel time for about 46.75 miles between San Francisco and San Jose is 57 minutes (four stops), 59 minutes (five stops) or 61 minutes (six stops), compared to 1 hour 30 minutes for local trains. The Baby Bullets have the same top speed of 79 mph (127 km/h) as other trains, but fewer stops save time. The CTX project included the purchase of new Bombardier BiLevel Coaches along with MPI MP36PH-3C locomotives. The Baby Bullets have proved popular, but many riders now have longer commutes on non-bullet trains, some of which wait for Baby Bullet trains to pass.
