That's a good question. Whether there should be a regulation or not, VIA Rail decided two years ago to work on the implementation of technologies that will achieve a good proportion of what a PTC system could bring at a much lower cost. We're in that route right now. We expect that within, let's say, probably four years we'll be able to put in place technologies that not only will help us understand the accidents but will mainly facilitate the job of our locomotive engineers by providing them with more information on what's going down on the track, and provide us with information on the reaction of locomotive engineers so that the system has the capacity to intervene if there's a reaction that is not in line with what it's supposed to be.
If there's a regulation, that's fine. But right now VIA Rail is not waiting for a regulation. We're working on implementing some technology that we believe will have a significant impact on safety in the short term.
