Caltrain is working on bridge and track improvemenets.
As part of the Marin & Napoleon Rail Bridge Improvement Project, the replacement of the Napoleon Street Bridge will require two weekend service closures. Caltrain [did not] operate service to the 22nd Street or San Francisco stations the weekend of April 17-18 and [will not on the weekend of] April 24-25.
On these weekends, free SamTrans bus service will replace train service between the Bayshore, 22nd Street and San Francisco stations. Buses are ADA accessible, will have limited capacity for luggage and bikes onboard and require face coverings while on board.
Riders are advised to check the revised schedule for the affected weekends to ensure they get to their destination on time. Southbound buses depart 25 minutes earlier from San Francisco station and 22 minutes earlier from 22nd Street station. There are no changes to departure times from Bayshore Station and all stations south.
Caltrain strongly recommends riders traveling to watch the San Francisco Giants or the Golden State Warriors on the weekend of April 24-25 to use BART at Millbrae station or an alternative transit option, due to limited capacity on buses and social distancing requirements that will make it difficult to accommodate the influx of riders.
The bridge improvements are needed to ensure the safety of community members and Caltrain passengers. This is the only time over the course of the project that service should be impacted to this extent.
The Napoleon Street Bridge will need to be fully replaced to reinforce its structural integrity. Work on the Marin Street Bridge focuses on minor safety improvements. Additional track work will occur between Cesar Chavez and Jerrold Street.
