Over the past several months, Caltrain has been performing work on the four train tunnels in San Francisco to pave the way for Caltrain Electrification and to bring the tracks to a state of good repair. On March 29, Caltrain completed the last of the weekend service shutdowns needed for electrification work which includes the installation of over 630 drop tubes and over six miles of overhead wire and conductor rail! Thank you to all of our riders for your patience as we work to modernize the Caltrain system.
