Thank you, Mr. Dhaliwal.
You mentioned, first, the main-track accidents, and Cheakamus was a main-track accident. The accident subsequent to that, at Lillooet, was also a main-track accident. And that's something that we've been focused on at CN.
Main-track accidents tend to have either a mechanical or an engineering cause—a broken wheel, a broken rail, things of this nature. We've invested tremendously over the past several years to increase the density of our wayside inspection network. We have also increased the frequency of inspections for rail flaws, as well as the number of times we inspect our track for track geometry issues. Accordingly, our 2010 main-track accident experience has been the best on record. Of course, one accident is too many, and we continue to focus on improvements in this regard.
With respect to your comment about safety culture, we used the Railway Safety Act review and the study of this committee as a catalyst. We worked much harder and in a more collaborative way with our union leadership and our employees to develop our safety culture. Based on the catalysts provided by those two studies, we've undertaken a number of initiatives over the past several years, especially since 2007, to work on safety culture. We're pleased that a number of the initiatives we've undertaken at CN, in cooperation with my colleagues at VIA and CPR, have been adopted as best practices in publications that Transport Canada has recently put out on safety management systems and on safety culture.
It's always a work in progress, Mr. Dhaliwal. One accident is one too many. Can I stand here and tell you that we won't have any more accidents? I'm afraid I can't, but it's something we're tremendously focused on. Nothing is more important to us than operating safely.
