In fact Canada has a framework for what employees can do on the job, specifically the people on the trains, that is much more helpful in being able to give people, those who come in and operate, options for being able to book rest. In the U.S. system—we have a railroad on both sides—it's a different set of regulations and a different set of rules with regard to what the employer and the employees and the union have.
I think Canada has a better system. Employees in Canada are allowed to take 48 hours off on our railroad after they've worked the equivalent of a workweek. They can book rest for 48 hours. They're allowed to book up to 24 hours' rest after they come in from a round trip. Those are things you can't do in other places. I think Canada has a regulatory framework and a fatigue framework, that is further advanced than anybody else's.
