Caltrain has claimed the life of another pedestrian in two weeks. This morning, a man was struck at the San Mateo station. According to reports, "he collision happened at 6:43 a.m. when southbound train No. 206 struck the man who Caltrain characterized as a trespasser on the tracks near 25th Avenue." It is not yet know whether or not this most recent fatality was an accident or suicide. Northbound and southbound trains are operating at normal speed, but you can "expect delays of 45-60 minutes" today. If you recall, a man and a woman, in separate incidents, sat down on the tracks at the San Antonio station earlier this month.
