A Canadian 'Via-Rail' passenger train derailed west of Toronto Sunday, killing three railroad employees and injuring dozens of passengers, officials said. 'Via-Rail' spokeswoman Michelle Lamarche said the three people killed were all engineers riding in the cab of the locomotive at the front of the train when it derailed in Burlington, Ontario. A fourth 'Via-Rail' worker in the locomotive was injured, she was quoted as saying by the Associated Press. Burlington Mayor Rick Goldring also confirmed that three people died in the accident.
