PORTLAND, Maine (AP) — A U.S. bankruptcy judge on Friday approved a $338 million settlement fund for victims of the fiery 2013 oil train derailment that claimed 47 lives in Quebec. The disaster led to greater regulatory scrutiny of the use of trains to transport crude oil amid a production surge thanks to new technologies including hydraulic fracturing. Canadian Pacific owned the track where the crude oil shipment originated and contended it bore no responsibility, since the train that derailed had a Montreal, Maine & Atlantic locomotive and crew and was operating on MMA rail.
