A Caltrain train struck and killed a person Saturday afternoon in San Francisco, according to authorities. The collision marks Caltrain's 11th fatality this year.

The incident happened just after 1 p.m. when a northbound train hit a person just south of a tunnel near Cesar Chavez and Evans streets, Caltrain officials confirmed. The train was heading from the Bayshore Yard to the 22nd Street Yard.

Approximately 279 passengers were aboard the train when the person was hit, but no other injuries were reported, Caltrain added.

The train was allowed to continue north to San Francisco with only one track remaining open with a speed restriction.

Investigators remained on the tracks investigating the incident, but both directions had been reopened as of 2:20 p.m., according to Caltrain.

"The final cause of death and identification of the individual will be determined by the city of San Francisco’s Office of the Chief Medical Examiner," a Caltrain spokesperson told The Standard via email. "No matter what the circumstances, it is always regrettable when a life is lost."
