Police raided the Canadian office of a U.S. railway company to collect evidence in a criminal investigation related to an oil train derailment this month that devastated a Quebec town and killed 47 people. Quebec provincial police inspector Michel Forget said Thursday that officers are searching the offices of Montreal, Maine & Atlantic Railway to collect undisclosed evidence. The company owned the train that was carrying crude oil when it derailed and exploded in downtown Lac-Megantic on July 6. The company’s director of administration, Sara Osborne, says she is aware of the police operation but isn’t offering details. The company already faces a number of wrongful-death lawsuits in the disaster.
