A person was struck and killed by a Caltrain train at the Atherton Station on Sunday afternoon.

A Caltrain spokesperson told SFGate the incident occurred at 12:53 p.m. with a southbound train carrying over 1,000 passengers.

On Twitter, Caltrain is reporting that delays are expected on trains in both directions, and a bus bridge has been set up serving the Redwood City, Menlo Park, Atherton and Palo Alto stations.

The Atherton station is open only on weekends.

This is the eleventh fatality for Caltrain this year so far. The incident is under investigation.
