Caltrain Construction Weekly Notice
February 6 to 10
Upcoming Caltrain Weekend Service Shutdowns
To finish critical Electrification construction and testing in time to begin passenger service in 2024, Caltrain will be suspending rail service in select areas on weekends throughout the year starting February 11, 2023. The first shutdowns will be between San Francisco and Millbrae for four weekends in February and March. Riders should avoid Caltrain on these weekends and seek alternative transportation if they are planning to travel. Bus bridge service will be available to Caltrain-dependent riders, but passengers should expect delays and longer travel times. Visit www.caltrain.com/status for the latest information about weekend impacts.
Weekday service will not be impacted. For more information about Caltrain’s weekday schedule, visit www.caltrain.com/schedules.
Caltrain Electrification
Caltrain Electrification is a key component of the Caltrain Modernization program which will electrify the Caltrain Corridor from San Francisco’s 4th and King Caltrain Station to approximately the Tamien Caltrain Station.
The primary purpose of Caltrain Electrification is to improve Caltrain system performance, reduce long-term environmental impact by reducing noise, improving regional air quality and reducing greenhouse gas emissions. An electrified Caltrain system would better address Peninsula commuters’ vision of increased service and improved travel times in an environmentally friendly and reliable way. This also is expected to help accommodate increase system ridership through improved system operations.
