I think whenever you have regulations, obviously that's the standard that's set for the general population to deal with it.
In our situation, one of the reasons is isolation; there are times when quite often we need two crews on our train, so we would have four people, not necessarily all working at the same time, but now that we've increased our times and our delivery times, we can run with two and we've just made that decision as a company.
For us, it's about creating an atmosphere of safety among not only your employees but also the people that you travel through. As I said earlier, we made the decision to go to five miles an hour after discussions with the communities. They felt that they would be safer should something happen, and it didn't actually interfere with our deliveries.
