OTTAWA, Oct. 29, 2013 /PRNewswire/ - Claude Mongeau, president and chief executive officer of CN (TSX: CNR) (NYSE: CNI), said today Canadian railways have a solid record of improving their overall safety performance and remain committed to achieving further safety gains. Mongeau, speaking to The Canadian Chamber of Commerce's International Trade Day, said: "The devastating rail accident in Lac-Mégantic, Que., last summer remains a sobering reminder that safety must be an absolute priority to prevent accidents from harming communities and the environment. "Rail safety is understandably under intense scrutiny as a result of the Lac-Mégantic accident. But as we engage in a review of what the rail industry can do to further improve safety, we should not lose track of the industry's strong safety record and the significant improvement trends achieved in recent years. The fact is that railways' mainline accident rate per million train miles declined by more than 40 per cent between 2001 and 2012 as a result of sizable investments in rail infrastructure, improved safety processes and a continuing focus on employee training and safety awareness. "Another fact to keep in mind is that railways move hazardous materials with a high level of safety. A full 99.997 per cent of rail movements of dangerous goods - many of which are essential to the North American economy and communities across the continent -- arrive at their destination without a release caused by an accident." Mongeau said CN and the rail industry are responding proactively to the Lac-Mégantic accident by taking a comprehensive view on ways to achieve further safety improvements. Rail industry partners are also taking steps to ensure safe loading and unloading procedures, properly identify dangerous goods, and look at ways to improve tank car safety, he said. Mongeau said CN understands that communities have the right to know more about the types of commodities moving their midst. "CN already works closely with communities by helping them prepare for and to respond to a possible dangerous goods transportation incident.
