Canadian National Railway derailment numbers soared before recent crashes: analysis

Toronto

CANADIAN National (CN) Railway's safety record deteriorated sharply in 2014, reversing years of improvements, as accidents in Canada blamed on poor track conditions hit their highest level in more than five years, a Reuters analysis has found.

Canada's Transportation Safety Board (TSB) said recently that track failure may have played a role in CN's three recent Ontario accidents, which have fuelled calls for tougher regulation. The agency said oil unit trains, made up entirely of tank cars, could make tracks more susceptible to failure.
