If I may, I have a general comment in terms of the requirements for addressing fatigue as well as the safety management system regulations that are in place. We do have work-rest rules that are in place, on top of the rules that are in place that are enforced and overseen by Transport Canada. In fact, some action has been taken where we found problems with compliance to those rules. We have and will take action, and we have no hesitation in taking action.
I would also say, though, in general, that this is an issue that does require considered work and continued work. As in all cases of areas of critical importance to the safety of railway operation, it can continuously be improved. In principle, I think it's fair to say that there are obligations and there are accountabilities. Certainly, the railway companies, the employees, and Transport Canada all work together to address those issues.
