Caltrain is a descendant of the San Francisco Peninsula’s oldest intercity passenger rail system, which began in 1863 as the San Francisco and San Jose Railroad Co.  The service provides a fast, convenient alternative to driving the heavily congested Bayshore Freeway, (Highway 101) between San Francisco, San Jose and south to Gilroy. This popular commuter rail service continues to attract new commuters and travelers with major upgrades completed between 1995 and 2004.  Up to twenty 80-mph limited stop “Baby Bullet” express trains run weekdays between major stations taking just 57 minutes to complete their runs between San Jose and San Francisco.

Caltrain passenger coaches are of two types.  “Baby Bullet” trains with newer bi-level Bombardier equipment offer 110-volt AC power outlets with tables for laptops and other electronic devices.

Older gallery cars also have seating on two levels. All trains have restrooms, baggage racks, bicycle storage and seating reserved for seniors and people with disabilities. Wheelchair boarding assistance is available at most stops.

Ticket machines are available at all stations. Ticketing is based on the honor “proof of payment” system; if caught on board without a valid ticket during a random inspection, a fine could result in addition to being put off of the train.

The right-of-way from San Francisco to San Jose Tamien station is publicly-owned by the Peninsula Corridor Joint Powers Board. Between San Jose and Gilroy, Caltrain runs on tracks owned by Union Pacific Railroad, a private company that hauls rail freight.

Caltrain projects

Caltrain currently is pursuing electrification.  Electric trains will provide faster starting and stopping, permitting more trains on tighter frequencies.  Construction began in July 2017 and is expected to be completed in 2021-2022. Caltrain is also pursuing various projects to improve tracks, rebuild or eliminate grade crossings, and upgrade its signal system.
