Frequently Asked Questions
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 fall 2024. 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.
Visit the Caltrain Electrification Construction page for updates on the latest construction activities and testing.
