Caltrain officials announced they will be suspending services between San Francisco and Millbrae Stations on multiple weekends this month.

The commuter rail line’s trips will be suspended on Aug. 12 to 13, 19 to 20, and 26 to 27 for its electrification project, officials said in a news release Tuesday.

“Crews will install and test the signal system in San Francisco and continue to erect poles and hang wires for the overhead catenary system (OCS),” they said.

Commuters were encouraged to look for alternative transportation, such as the bus bridge service. Riders were advised to expect delays and longer travel times with the bus system.

Under the rail line’s project, diesel trains and their infrastructure components will be transitioned to an electrified system, Caltrain officials said.

“The new trains will feature on board displays with digital trip information, increased storage capacities, baby-changing tables, Wi-Fi and power outlets at every seat,” officials said, adding the project also aims to meet climate action goals.

Caltrain is expected to launch passenger service under the electrified system in fall of 2024.
