Located at the intersection of 2nd and King Streets, the station provides critical rail access for commuters traveling between San Francisco and cities in San Mateo and Santa Clara counties.

The station plays a vital role in regional transit connectivity, linking rail, bus, and light rail services. Since its opening, it has become one of the busiest stops on the Caltrain line, particularly for tech industry workers and downtown employees.

• Opened in 1998 as part of the Third Street Light Rail Project, the station was designed to improve transit access to the growing South of Market (SoMa) district.
• The station is officially named 2nd and King Station, though it is sometimes referred to as Caltrain’s San Francisco Station.
• It is situated just 0.3 miles south of the Salesforce Transit Center, allowing for seamless transfers between regional and local transit systems.
• The platform accommodates eight-car trains, supporting Caltrain’s electrified fleet introduced in 2024.
• As of 2023, the station sees over 18,000 weekday boardings, making it one of the most heavily used stops on the line.

How It Works

2nd and King Station functions as both a commuter rail stop and a multimodal transit interchange, integrating services from Caltrain, Muni Metro, and regional buses. Its layout and scheduling are optimized for peak-hour commuter flows, especially during morning and evening rush periods.

• Caltrain Service: Operates from 5:00 AM to midnight, with limited, express, and local trains serving 22 stations from San Francisco to Gilroy.
• Electrified Trains: Since 2024, electric multiple units (EMUs) have replaced diesel trains, reducing travel time and emissions on the line.
• Muni Metro Connections: The station is directly linked to the K Ingleside, L Taraval, M Ocean View, N Judah, and S Shuttle lines via the nearby Muni Metro stop.
• Bus Access: Multiple San Francisco Municipal Railway (SFMTA) bus lines, including the 9, 14, and 30, stop within one block of the station.
• Fare System: Uses Clipper Card and mobile payment systems; Caltrain fares range from $4.10 to $15.20 depending on distance.
• Accessibility: Fully ADA-compliant with elevators, tactile paving, and real-time arrival displays for all platforms and entrances.
