I can't put a number on how many trains or what kind of commodity has been delayed as a result. However, it is an extremely important part of our safety focus. We have undertaken various pilots with our operating unions, not just pilot projects but scheduling schemes in various major terminals to start to get regularity of service so an employee knows when they're going to work. They can better prepare and better plan. We started that almost two years ago and continue to roll it out throughout our system.
For both railways, and I speak on behalf of CP, fatigue and safety are of the utmost importance for us.
