A Sunnyvale man apparently stepped off the San Antonio Station passenger platform into the path of a speeding Caltrain commuter at 5:08 p.m. Monday, according to Caltrain spokesperson Christine Dunn.
He has been identified Christian Edward Archibald, 31, of Sunnyvale, according to Jesse Montano, spokesperson for the Santa Clara County Medical Examiner-Coroner's Office.
The train was a "limited stop" train that was going between 73 and 79 miles per hour, Dunn said.
The train was stopped some distance south of the station and other southbound trains were single-tracked on the northbound tracks starting at about 5:40 p.m., Dunn said.
Caltrains were delayed between 30 and 60 minutes until after 7 p.m.
Tracks were reopened to regular service at 8:30 p.m.
A tall steel fence separates the tracks to prevent any crossover by pedestrians.
Monday night, long strands of yellow "caution" tape prohibited pedestrians from entering the station as a dozen officials combed the scene. A white stretcher stood on the platform, empty.
A few passersby paused to survey the station.
Dunn said the death is the fifth track fatality of 2010, somewhat below the rate of 2009, when there 19 deaths on Caltrain tracks -- the second highest year since 1995, when there were fewer trains running at slower speeds.
