I'll make two comments. One is the point that was made twice already about integration. It's a comment that I've heard from some of our head offices--we have several offices--and it is that they find it odd that Canada doesn't have an integrated transportation policy for the whole country. There are different groups that are responsible for different levels of transit or transportation in Canada, but there's not one policy for the whole country, and I think that's why we don't have integrated systems.
We have intercity trains coming into certain areas, but they're not connected to anything to get out of the station. Somebody asked me the other day if, when you go to Montreal by train, it is easy to get out of that station, and if there is a major bus terminal right there so that you can get on any bus to go anywhere in the city. I said no, that you get on the subway and you make your best efforts to go to where you want to go. It's similar in Toronto and so on.
About the infrastructure costs, there aren't many numbers out there for Canadian railway infrastructure construction. The rule of thumb for CN and CP, the two major railways, is that basically when you have the land and you're building the best classification of track system under the standards we have today, for single track, you'd be looking at, let's say, $1.5 million per mile.
