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.

Some alternatives to Caltrain include:

• SamTrans ECR – Palo Alto to Daly City via El Camino Real
• SamTrans 292 – Hillsdale Caltrain Station to San Francisco
• BART Red/Yellow Line – Millbrae to San Francisco via Daly City
• Amtrak Capitol Corridor – San Jose to Oakland via East Bay

There will be signage located at the Caltrain stations to guide passengers to the bus stop locations. Look for "Weekend Bus Bridge" signs.

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.

How will weekend service be affected?

On the weekends of March 25-26 and April 1-2, train service for local Caltrain-dependent riders will be replaced with bus service between Millbrae and Hillsdale stations on several weekends. The weekend bus bridge will serve all stops between Millbrae and Hillsdale stations.

Use alternative transit options during these weekends.

• Plan for additional travel time of 60 minutes due to the bus bridge when traveling through the affected area.
• The last northbound train will depart San Jose Diridon Station at 10:05p.
• The last southbound bus will depart San Francisco Station at 11:04p.

There will be additional weekend shutdowns throughout 2023. For the latest information on weekend service changes, this page will have the latest information about upcoming service changes. 

Do I have to pay to ride the bus service during these weekends?

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.

How do I use a Clipper Card when the stations are closed?

If you are using a Clipper Card while traveling on both the bus bridge and rail service, please remember to tap your card upon boarding the train and again upon exiting the train at your final destination.

Are the buses ADA accessible?

There will be one accessible vehicle per trip. Please note that capacity will be limited. We encourage all passengers to plan ahead and use alternative transportation options when available.

Can I bring my bike onboard the bus?

Customers are allowed to bring their bikes onboard the bus; however, please note that space is limited to a maximum of 3 bikes at a time on each bus and there may be as few as two buses on a given trip. Buses are not equipped with bike racks; rather, bikes will be stored in the luggage compartment, space permitting. Use alternative transit options when possible and consider using bike parking options that are available at every affected station. More information at www.caltrain.com/bikes.
