A U.S. railway company whose runaway oil train caused an explosion and fire that killed 47 in a small town in Canada filed for bankruptcy protection from creditors on Wednesday. The Montreal, Maine, and Atlantic Railway (MMA) filed for bankruptcy protection in U.S. and Canadian courts, citing debts to more than 200 creditors following the July disaster in Lac-Megantic, Quebec. MMA chairman Ed Burkhardt previously had said a bankruptcy filing was likely due to service disruptions because its rail line remains closed in Lac-Megantic. The railway also faces lawsuits and enormous cleanup costs following the July 6 derailment and disaster in the Quebec town.
