Caltrain service into downtown SF resumes Monday

With pre-electrification tunnel modification work set to wrap up for the weekend by 3 a.m. Monday, regular Caltrain service to the 22nd Street and Fourth-and-King Street downtown station is expected to resume in time for the Monday morning commute, the agency said Sunday night.

Such work on the tunnels, to prepare them for future electrified trains, is being carried out each weekend through spring. That work forces trains from San Jose and Gilroy to terminate at the Bayshore station, with SamTrans buses connecting train riders with the 22nd Street station and the downtown station.

Caltrain’s electrification is scheduled to be operational by 2022.
