That is a very good question. I will begin and then I will ask my colleagues to answer your question as well.
I think in terms of fatigue, probably the most significant thing we could do to monitor what's going on with our workers, especially the drivers of trains, is to introduce video technology into the trains.
The one thing that's preventing us from doing that has been a debate about whether that is by unions or in legislation. It's something we're working on. In fact, I had a meeting with the Transportation Safety Board yesterday to talk about this. We'd like to work collaboratively with them to introduce it, but like anything else, it's complex.
To me, it's something that's going to have to happen. The technology, obviously, is a lot less expensive than it used to be. I think the public would have an expectation that in terms of safety, we need to know what's going on, and we need to use that technology to prevent accidents. Whether it's monitoring fatigue or it's determining whether drivers are getting bored and starting to text or to use iPads or any of the myriad of technologies we have today, I think we would see significant benefits from the introduction of that technology.
