Caltrain is a commuter rail transit system that serves the San Francisco Peninsula and the Santa Clara Valley in the U.S. state of California. It is operated under contract by TransitAmerica Services and funded jointly by the City and County of San Francisco, San Mateo County Transit District (SamTrans), and Santa Clara Valley Transportation Authority (VTA) through the Peninsula Corridor Joint Powers Board (PCJPB). The system's average mid-weekday ridership is 65,095 as of February 2018.
The original railroad between San Francisco and San Jose (known as the Peninsula Commute) was built by the San Francisco and San Jose Rail Road in 1863. In 1870 the railroad was acquired by Southern Pacific. Southern Pacific double tracked the line in 1904. In 1958 the railroad had record ridership, 7.5 million passengers. The popularity of the railroad began to decline and in 1977 Southern Pacific petitioned to the state government to discontinue Peninsula Commute. After months of negotiation, the California Department of Transportation (Caltrans) reached an agreement with the three counties of which the Peninsula Commute ran through to continue rail operation. Under the agreement, the system was renamed Caltrain and operation responsibilities were shared by Caltrans, Southern Pacific and the three counties. The Peninsula Corridor Joint Powers Board was formed in 1987, and it bought the right of way of Caltrain from Southern Pacific in late 1991 for $220 million. The PCJPB formally took over the operation of Caltrain in 1992 and contracted Amtrak to operate the system. In the same year, Caltrain extended to Gilroy. Amtrak's contract with PCJPB was renewed in 2001.
The system has 31 stations. 28 stations are served daily, one (Broadway) is served on weekends only, one (College Park) is served during Bellarmine College Preparatory's commute times on weekdays only, and one (Stanford) is served on Stanford University's football game days only. San Francisco 4th and King Street is the northern terminus of the system, while Gilroy is the southern terminus. The five southernmost stations—Capitol, Blossom Hill, Morgan Hill, San Martin, and Gilroy—are served only on weekdays during commute times, by select trains. Twelve stations are served by the express train service known as Baby Bullet, inaugurated in 2004. Seven stations (Millbrae[a], Burlingame, San Carlos, Menlo Park, Palo Alto, Santa Clara, and San Jose Diridon) are listed on the National Register of Historic Places.
Of the 31 stations in the system, 27 are accessible. The four that are not are, in order from north to south, 22nd Street, Broadway, Stanford, and College Park. The weekend-only Broadway station is planned to be completely rebuilt; upon completion, it would be ADA-compliant. The non-accessible Atherton station was closed on December 13, 2020. Of the four non-accessible stations in the system, only 22nd Street sees regular service.

- Millbrae station's original depot and platforms were closed in 2003 when Caltrain relocated to the new Millbrae Intermodal Terminal just to the north. The depot now houses the Millbrae Train Museum.
- Station mileposts are based on track distance from the former 3rd and Townsend Southern Pacific Depot 0.2 miles northeast of the current San Francisco station. Actual station distances south of Lawrence station no longer match the given mileposts (e.g. current track distance from San Francisco to the San Jose station is 46.8 miles).
- Caltrain charges zone-based fares. Fares are based on the number of 13-mile zones the passenger travels in.
- Three-letter station abbreviation.
- Ridership counts the average number of mid-weekday boardings at the listed station in January & February 2018.
- Bullet service limited to reverse commute (northbound trains in AM, southbound trains in PM)
- At this station, Caltrain applies a "hold-out rule": a train cannot enter the station when a train on the other track is stopped at the station for passengers.

- Prior to 2018, Caltrain counted "average weekday ridership" by counting riders on all weekday (Monday through Friday) trains for one week and computing the average as the sum of all riders over one week divided by five. In 2018, Caltrain shifted to counting "average mid-weekday ridership" by counting riders on trains on two of the three mid-weekday days (Tuesday, Wednesday, and/or Thursday) for two weeks and computing the average as the sum of all riders on the four mid-week days divided by four. An examination of mid-weekday ridership data from 2013 through 2017 showed ridership on these three mid-weekday days is approximately equal. Since Monday (-1% compared to mid-weekday ridership) and Friday (-9%) trains tend to have lower ridership than mid-weekday trains, the pre-2018 "average weekday ridership" results in a count approximately 2% less than the 2018+ "average mid-weekday ridership" methodology.
