No.
We looked at that system and there's a lot more to it than that. You come in for 12 hours, you have no idea where you are going, which way you are going, whereas right now our on-call people work a pool but they know where they're taking the train to and they know where the train is coming back from. Under that system it was just come in for 12 hours, we'll send you where we're going to send you, or we may not send you anywhere, then we'll put you up for rest for the appropriate amount of time and then you'll go back for 12 hours again.
That's not a system that we thought really addressed any of our needs here. They also have different hours-of-service rules in the United States, so that model was based on their hours-of-service regulations in the U.S. If we adopted a similar system here it may be a solution, but right now it's not.
