Caltrain Explores Options for New Headquarters

Caltrain has issued a Request for Information (RFI) from property owners, managers or their qualified broker representatives to assist with identifying potential new office space for its headquarters.  

Caltrain currently shares a headquarters with SamTrans in San Carlos near the San Carlos Caltrain Station. In 2025, SamTrans is planning to move to a new headquarters building located near the Millbrae Caltrain Station and has offered Caltrain the option to continue to co-locate. Caltrain is evaluating this opportunity, while also exploring other options to lease or purchase separate office space near a Caltrain station. 

Caltrain is seeking to acquire 27,000–35,000 square feet of office space near a Caltrain station on the San Francisco Peninsula, either through a lease or purchase agreement. Caltrain is interested in hearing from the private sector as well as public entities. Submissions shall be considered as expressions of interest to sell or lease properties described. The RFI is available for download here: 

Interested firms are requested to submit one electronic PDF version of their submission to by 1:00 p.m. PT on Monday, April 22. 

Caltrain’s historic Electrification Project is the first undertaking in North America in a generation in which diesel trains and their infrastructure components are transitioned to an electrified system. Electrification means faster and more frequent service, including doubling the frequency on weekends. The passenger experience will be greatly improved as well with the new trains featuring Wi-Fi, power outlets at every seat, onboard displays with digital trip information, increased storage capacities.   

Electrification will also help meet ambitious regional and state climate action goals by lowering greenhouse gas emissions, improving air quality, and relieving traffic congestion. Additionally, electrified service will advance equity along the corridor by reducing noise and air pollution while increasing access for priority equity communities. It will also set the framework for California’s future High Speed Rail network that will run on the Caltrain corridor.   

The proposed Electrification service plan would see weekday peak hour trains go to 79 stations per hour, an increase from the current 66. Eleven stations would experience four train arrivals hourly per direction, a notable improvement from seven stations currently. Midday trains would cover 44 stations per hour, up from 34 today.


About Caltrain: Owned and operated by the Peninsula Corridor Joint Powers Board, Caltrain provides rail service from San Francisco to San Jose, with commute service to Gilroy. Serving the region since 1863, Caltrain is the oldest continually operating rail system west of the Mississippi. Looking to the future, Caltrain is set to electrify the corridor by 2024, which will reduce diesel emissions and add more service to more stations while advancing the agency’s equity goals.
