Temporary Hillsdale Station Closure

Sign Up for Project Updates

Background Information

In order to complete the 25th Avenue Grade Separation Project that will improve safety, traffic flow, and reduce train noise, Hillsdale Station will be temporarily closed for up to six months starting in December 2019. This will allow for the transition from ground-level tracks to elevated tracks; the creation of an east-west connection at 28th Avenue; and the building of the new Hillsdale Station without interrupting Caltrain’s passenger service that serves 63,000 daily commuters. When complete, the new landscaped station will be located at 28th Avenue with updated amenities.

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.
