On the weekends of May 20-21, 27-28, and June 3-4, Caltrain will run regular weekend service. There will not be service shutdowns or bus bridges on these weekends. 

On May 21, Caltrain will run two special service trains in advance of the Bay to Breakers race in San Francisco. For more information on that service, visit the Bay to Breakers Page.

Local weekend Caltrain service will be replaced with a lifeline bus bridge between San Francisco and Millbrae for Caltrain dependent riders. Use alternative transportation options during these weekends.

Buses will have limited capacity for luggage and bikes. Use bike parking options, which are available at most stations. Buses will be ADA accessible. We encourage all passengers to plan ahead and use alternative transportation options when available.

If you are using a Clipper Card while traveling on both the bus bridge and rail service, please remember to tap your card at the Clipper® reader upon boarding the train and again upon exiting the train at your final destination. Caltrain customers using the bus bridge portion of their trip do not need to make an additional payment.

Weekend service shutdowns will affect the following Giants games in June: 

• June 10: Giants vs. Cubs
• June 11: Giants vs. Cubs

Expected significant delays and limited capacity on these dates. Please plan ahead and use alternative transit options. 

For all other home games, Caltrain is still the best way to the ballpark.

We encourage riders to plan ahead and consider alternative transportation options. Riders can also use transit planning services like Google Maps, Apple Maps, or the Transit App.

Why is Caltrain temporarily suspending weekend service in certain areas?

The Caltrain Electrification Project will provide passengers with greener, faster, and more frequent service, and is nearing its final phase as we prepare for the start of passenger service in 2024. In 2023, we need to do intensive work along the corridor to complete critical construction and testing activities. To minimize the impact on weekday service and to ensure the project is completed safely and on time, Caltrain will be suspending rail service in select areas on weekends throughout the year starting in mid-February.

Visit the Caltrain Electrification Construction page for updates on the latest construction activities and testing.

Are the buses ADA accessible?
