The Caltrain station at Fourth and King in San Francisco was shut down Thursday morning after a man climbed a power pole, according to the rail agency.
Both inbound and outbound Caltrain service was affected as police responded to the scene. Video showed a man on top of a power pole at the station.
A Caltrain spokesperson later confirmed a trespasser had climbed onto equipment at the station, and police were trying to detain him. At about 9 a.m., the man had climbed down.
Travelers were advised to expect delays and use alternate routes, an alert from AlertSF said shortly after 6 a.m. Even after the man removed himself from the power pole, Caltrain said it would take about an hour to resume operations at the station.
Caltrain said it was running a bus bridge between San Francisco and the 22nd Street Station so riders can connect with trains and get to their final destinations.
There were no further details about the police activity.
