On Monday, the Everett woman, who worked as a supervisor with Rail Terminal Services, and her husband filed a lawsuit against Union Pacific in King County Superior Court.
The couple is seeking compensation for more than $125,000 in medical bills, Beffert's lost income and general damages for pain and emotional distress, said their attorney, Bruce Clark.
"Over the past six months we've attempted to reach some kind of settlement with Union Pacific, but we've received no offers," Clark said.
The company reportedly was declining comment on the suit.
