A woman was killed Monday evening after she walked — unknowingly and distractedly, it appears — in front of a TRAX train.

Marta Young, 66, was crossing the tracks near 5900 S. 300 West at an intersection, not a station, about 4:30 p.m., said Carl Arky, spokesman for the Utah Transit Authority.

The gates were down and the lights were flashing, Arky added, but Young appeared not to notice, according to a police review of UTA surveillance footage. The woman, who lived in Midvale, had her head down and walked in front of a southbound train.

“Every warning signal was operating properly,” Arky said. “She just wasn’t paying attention for some reason.”

Arky said officers do not suspect Young walked in front of the train intentionally and are investigating to see if she was wearing headphones or was otherwise distracted.
