Caltrain

Caltrain is a commuter rail service that operates in the San Francisco Bay Area of Northern California. The system connects the urban centers of San Francisco, San Jose, and several other cities in the region. Caltrain's primary service area is the San Mateo County coastline, but it also extends into northern Santa Clara County and southern San Francisco County.

Caltrain operates 92 miles of rail lines, with 92 stations along its route. The commuter rail service is the primary mode of transportation for many residents of the region, particularly in areas where there is no convenient highway access. The system's peak hours see over 60,000 passengers per day.

Fares on Caltrain are based on a zone system, with passengers paying according to the distance they travel. The cost of a single ticket ranges from $3 to $12.50, depending on the length of the trip. Caltrain offers several types of passes for frequent riders, including a monthly pass that offers unlimited travel for a fixed price.

Caltrain trains operate multiple times per day, with services leaving from the end of the line at the 4th and King Station in San Francisco and the Tamien Station in San Jose. Some express trains run during peak hours to reduce travel time, while local trains make all regular stops. Caltrain offers additional services, including electric commuter trains and extended capacity weekend services.

Caltrain is owned and operated by the Peninsula Corridor Joint Powers Board, a public agency consisting of representatives from San Francisco, San Mateo, and Santa Clara counties. The agency has an ongoing project to electrify the system and increase capacity, with completion expected in the mid-2020s.
