As of May 16, 2020, Caltrain’s Hillsdale Station in San Mateo is temporarily closed through Fall 2020 as part of the 25th Ave Grade Separation Project.

During the closure, trains that normally stop at the Hillsdale Station now serve the Belmont Station instead. A new weekday and weekend timetable, effective May 16, is available on the schedules page.

Belmont and Hillsdale Stations are both in Fare Zone 2, meaning applicable ticket prices will remain the same for paper / mobile tickets and Clipper card purchases.

Upon completion of construction, the Hillsdale Station will be relocated about one block north of its current location, between 28th and 31st Avenues. The new station will have an elevated center-boarding platform allowing for safer, more convenient pedestrian access.

What Hillsdale Station Passengers Need to Know


  • If you drive to Caltrain, use the Belmont Station parking lot as it has sufficient capacity. Parking at the Belmont Station is free of charge until the Hillsdale Station reopens for service.
  • The Hillsdale Station parking lots are closed.

About the 25th Avenue Grade Separation Project

Caltrain is working closely with the City of San Mateo to deliver this important safety project. When complete, the tracks will be separate from the road at 25th Avenue reducing horn noise and improving traffic flow; there will be two new east-west connections at 28th and 31st Avenues; and a new Hillsdale Station with updated amenities will better serve the community.
