Heaney was killed when a southbound train struck him just north of the San Antonio station at about 5:25 p.m. on Thursday, Feb. 25. Nobody on the train was injured.
The Santa Clara County medical examiner's office did not immediately release Heaney's final cause of death or his town of residence.
The tracks were temporarily shut down in both directions. The northbound tracks reopened soon after and trains were single-tracked through the area, Caltrain spokesperson Christine Dunn said. Tracks were open in both directions by 7 p.m.
Caltrain also experienced major service disruptions earlier the same day when northbound train No. 101 struck an unoccupied car that had been left on the tracks at Mary Avenue in Sunnyvale at about 5 a.m., Dunn said. (See News Briefs, page 6.)
"These incidents, including the tragic circumstances of this evening, are deeply troubling to Caltrain customers and staff and we regret the loss of life and the immense difficulties caused (to) individuals who depend upon the rail service," Caltrain spokesman Mark Simon said in a prepared statement Thursday.
This was the second fatality involving Caltrain this year.
