San Francisco Tunnel Work

Historic tunnel 4_ southernmost entrance.

Construction is advancing along the Caltrain corridor! To accommodate the brand new electric trains, construction crews will begin work in the four San Francisco tunnels starting in October. Crews will create additional clearance in the tunnel sides to accommodate the new trains and will install anchor bolts in the tunnel ceilings to facilitate the installation of the overhead contact system that will power the new electric trains. For more information visit .

In order to facilitate work in the tunnels, trains will not operate on weekends between San Francisco and Bayshore Stations from October 6, 2018 to late Spring 2019 . Caltrain service will stop at Bayshore Station and a bus bridge will transport passengers to the 22nd and 4th & King Stations. Weekday service will not be impacted. For more service information visit .


First wire installed in San Bruno.

The first mile of wire for Caltrain Electrification has been installed in San Bruno! Crews continue to pothole for utilities in South San Francisco to San Jose. Crews also continued construction of the traction power substation in San Jose which will provide power to the overall system once electrified.

What Is CalMod?

The Caltrain Modernization Program (CalMod) includes electrification and other projects that will upgrade the performance, efficiency, capacity, safety and reliability of Caltrain's service. The current electrification project will electrify the corridor from San Francisco to San Jose and replace 75 percent of Caltrain's diesel service with high-performance electric trains, reducing air pollution and providing better service to more riders.
