San Francisco

Salesforce Transit Center (STC) in San Francisco stands ready to receive high-speed rail trains and will serve as the northern terminus of the high-speed rail system.

The center, which is managed by the Transbay Joint Powers Authority (TJPA), opened to the public in 2018.

Salesforce Transit Center (STC)The STC will serve 11 transportation systems, including high-speed rail. The existing building includes all of the bus facilities, a rooftop park, retail, and the basement-level trainbox where high-speed rail and Caltrain trains will arrive. The Authority is working with partners in San Francisco to advance the Downtown Extension project, which is a 1-mile tunnel between the existing rail corridor and the trainbox in the Salesforce Transit Center.

Prior to completion of the Downtown Extension, high-speed rail will stop at the existing Caltrain station at 4th and King in downtown San Francisco.

This station community is part of the San Francisco to San José project section.


425 Mission Street between Beale and 2nd Streets. 


The Salesforce Transit Center was completed in 2018 and the Downtown Extension (DTX) project has been environmentally cleared by the TJPA. In 2020, the Authority, TJPA, and other partners in San Francisco entered into a Memorandum of Understanding (MOU) to advance the DTX toward construction. Once constructed, DTX will provide a tunnel to link the new STC to the existing terminus of the Caltrain commuter rail line at 4th and King Streets. Until the completion of DTX, the environmental analysis is studying the Caltrain station at 4th and King in downtown San Francisco as an interim station.
