I'll give you one example. The CN main line between Montreal and Toronto was running, a year ago--it's less today--when they were operating in a different kind of economy, roughly 85 trains a day, both ways. About a dozen of those trains were VIA trains. They were running roughly 70-plus trains a day.
If you go to a higher-speed model, as it was laid out, you have to anticipate that you're going to try to improve the frequency of the VIA trains. So you may end up with 20 or a few more a day. However, if you look at economic growth over time, and if we achieve some of the things we would like to achieve, with the development of the Port of Montreal and all the other things we want to do, I don't see any scenario in which the number of freight trains on that line is not also going to have to go up. I don't know how much, but it will be significant.
In the days before the recession, our freight traffic was growing at 5% plus per year. When you opt for that option, yes, you save money in the short term, and yes, you may be able to improve service for a period of time. However, you are going to look down the road at an eventual conflict between those traffic patterns. Because sooner or later, you're going to run into a capacity issue of significant degree.
The question is whether you bite the bullet now, put in the separated systems, with the higher speeds, knowing that it's going to have more front-end costs but in the long run will give you a more effective system, or not.
