Caltrain confirmed on Wednesday evening at about 5:40 p.m. that a fatality had occurred on the southbound tracks near Charleston Road on the Caltrain right of way.
The deceased appeared to be an adult male, according to Transit Police conducting an investigation at the scene.
Following the incident, which was reported by Southbound Train #264, service was stopped in both directions, with trains held at Palo Alto and San Antonio stations.
Caltrain cleared trains to travel on the northbound tracks, with both southbound and northbound trains going around the investigation.
Delays are expected, and Caltrain reported that VTA transit will honor Caltrain tickets. Plans for a VTA bus bridge have been cancelled.
Caltrain launched a "There is help" signage program and website with resources for individuals and those seeking to learn more about mental illness and suicide earlier this month. The website can be found here.
Further information will be reported as updates become available.
