San Francisco

Salesforce Transit Center (STC)

The 4th and King Street Station will serve as the interim terminal station for high-speed rail service until completion of the Downtown Rail Extension (DTX) project, which is a 1.3 mile tunnel that will extend the rail corridor to the train box in the Salesforce Transit Center.

High-speed rail trains will use the track built for DTX to reach Salesforce Transit Center — the ultimate terminal station in San Francisco.

STATION COMMUNITY DETAILS

Project Section

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

Location

700 4th Street, San Francisco 94107

Status

Until the completion of Downtown Extension (DTX) project, the environmental analysis is studying the Caltrain station at 4th and King in downtown San Francisco as an interim station.

The station improvements would include:

• Modifying existing tracks and platforms

• Installing a booth for high-speed rail ticketing and support services

• Adding high-speed rail fare gates

To support high-speed rail operations, two existing Caltrain platforms would be raised and lengthened to serve four high-speed rail tracks. Ramps would be installed to provide pedestrian access from the station building to the raised platforms. All other platforms and tracks would continue to be used for Caltrain service.

The Salesforce Transit Center was completed in 2018 and the DTX has been environmentally cleared by the Transbay Joint Powers Authority (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 STC to the existing terminus of the Caltrain commuter rail line at 4th and King Streets.
