Southeast Rail Station Study

The Southeast Rail Station Study (SERSS) explored options for future station locations on the Caltrain corridor in southeastern San Francisco.

On July 14, 2022, the Planning Commission endorsed the Study. This resolution urged decision-makers to take all steps for the Bayview Neighborhood to 1) restore Caltrain service to the Bayview, 2) commit funds to advance this long-overdue project, 3) recommend an Oakdale location, and 4) equity and connection should be prioritized. For the Potrero / Dogpatch / Mission Bay neighborhood the Commission urged decision-makers to: 1) advance design for the PAX and changes to existing 22nd Street station and 2) recommend the either the current location or a 16th and Mariposa location. On June 30, 2022, the final Southeast Rail Station Study was released. The San Francisco County Transportation Authority will lead the next steps of the work.

In partnership with Caltrain, the City of San Francisco is planning for the future of the Caltrain corridor between the existing 4th and King Station and the Bayshore Station.

The Electrification of Caltrain service is underway, which will bring more and cleaner train service to San Francisco. Future projects also include the future Pennsylvania Avenue Extension (PAX) tunnel that was adopted by the Mayor's Office and the Board of Supervisors at the conclusion of the Rail Alignment and Benefits Study in 2018.

The PAX tunnel is still under concept development and the final concept may require the redesign or relocation of the existing 22nd Street Station.
