South San Francisco Station Improvement Project

The South San Francisco Station Improvement Project built a fully-accessible station with a center-boarding platform, a new pedestrian underpass for east-west connectivity, and a West Plaza for easy access to downtown South San Francisco.


The station now features a 700-foot center-boarding platform and pedestrian underpass. Passengers no longer have to cross the tracks to board the train. The improvements also make the station fully compliant with the Americans with Disabilities Act (ADA).

The new platform also eliminates the “holdout rule” at the station. Before trains had to “hold out” outside the station if another train was at the platform. Multiple trains are now safe to enter or pass through the station, allowing for more flexibility in scheduling, which is critical for future increased electrified service.

This $96.6 million project is funded through a combination of San Mateo County Transportation Authority, City of South San Francisco, and Federal Transit Administration funds.
