Template:Short description Template:Use American English Template:Use mdy dates Template:Infobox public transit
AirTrain is a fully automated people mover at San Francisco International Airport (SFO) that opened on February 24, 2003. It operates 24 hours a day on two separate lines, covering a total of Template:Convert. The service charges no fares; it is funded by a fee charged to rental car customers.<ref>Template:Cite news</ref> The system is located outside of the sterile area of each terminal, meaning passengers must exit and re-enter through a security checkpoint when using AirTrain to travel between terminals.
Lines and stations
AirTrain operates on two lines—Red Line and Blue Line—both of which run every four minutes. The Red Line travels in a clockwise loop around the central terminal area, which takes about nine minutes to complete. The Blue Line travels in a counterclockwise loop, serving the same stations in reverse order, and also proceeding to West Field Road, the Rental Car Center, and long-term parking, which takes 25 minutes for a round trip.<ref name=":0" />

History
A $15 million infill station was constructed to serve the Grand Hyatt at SFO, a new airport hotel.<ref>Template:Cite news</ref> The hotel opened on October 7, 2019.<ref>Template:Cite press release</ref>
AirTrain did not originally provide access to SFO's long-term parking garage and lots; instead, passengers had to take a free airport shuttle bus between the airport terminals and the long-term parking areas. The original end of the track past the Rental Car Center station was only about Template:Convert away from the airport's long-term parking garage; an extension to the garage began service in May 2021, replacing the shuttle buses.<ref name=":0">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The extension is estimated to eliminate Template:Convert previously driven by the shuttle buses each year.<ref name=":0" />
The Harvey Milk Terminal 1 station was closed from July 2021 to April 26, 2023, during reconstruction of the terminal.<ref>Template:Cite news</ref>

The AirTrain system was built by Bombardier Transportation at a cost of US $430 million and is composed of 38 Innovia APM 100 cars coupled in trains of up to three cars. The APM 100 cars can also be found at airports in Tampa, Denver, Atlanta, Seattle-Tacoma, Houston, and Madrid. They are operated automatically under Bombardier's Cityflo 650 Communications-based train control signaling technology, making it one of the first radio-based train control systems to enter service.<ref name="CBTC15">Template:Cite press release</ref> The entire AirTrain fleet is accessible and allows rented baggage carts on board.
The Airport Development Plan from 2016 forecasted that ridership on the two lines would be over capacity in the future (42% and 87% over capacity on the Red and Blue Lines respectively)<ref>Template:Cite reportTemplate:Dead link</ref> and recommended upgrades that would increase capacity. Specific upgrades included acquiring 30 additional AirTrain cars, upgrading existing stations to accommodate 4-car trains, and upgrading the maintenance facility to accommodate additional vehicles.<ref>Template:Cite reportTemplate:Dead link</ref>Template:Clear left
