SYLMAR — A 24-year-old woman fell from a platform and was killed Monday when she was struck by a Metrolink train pulling into the Sylmar/San Fernando Station, despite a companion’s efforts to pull her to safety.

The victim was struck by Palmdale-bound Metrolink Train 285 just after 6 p.m. at the station in the 12200 block of Frank Modugno Drive, near the border with San Fernando, according to Chris Gutierrez of Metrolink.

The woman had been facing the tracks and at some point turned, slipped, and fell backward from the platform, according to Lt. Paul McLaughlin of the Los Angeles Police Department’s Mission Station.

A man witnesses said was the woman’s boyfriend jumped onto the tracks and tried to pull her to safety, but she may have been unconscious as the man was only able to move her a short distance before he had to jump out of the way, McLaughlin said.

The woman was pronounced dead at the scene.

The man’s leg was struck but he was not seriously injured. He and the woman’s mother and twin sister came to the Mission Station to try and find out the woman’s condition and if she had been taken to a hospital and were then notified that she had not survived, according to McLaughlin, describing a scene of grief when the notification was made.

The fatality halted train traffic through the station and officials arranged bus bridge service to get passengers to their destinations, Gutierrez said.
