These incidents happen once in a lifetime. We at CN have never had an accident like this. We learn from every one, but we did not have experience in this one, prior to this unfortunate event.
We have a lot better equipment now to address a spill, if we have similar issues. We have reinforced our protocol for the intervention at the site and the link with the experts who have the knowledge to address these kinds of events and we have extensively debriefed about how to better communicate and deal with people's anxiety with a more effective, more proactive communication program with the people who are impacted on the site.
As I said, this incident will have cost CN more than $100 million. We have learned a lot from it and we hope we never have to use it.
