One of the factors with maintaining rail in Canada is that we run huge freight trains, and probably the weight of the trains would have more of an effect. The high-speed trains are fast, but they're not heavy. Where you get more damage to the rail and what makes it more difficult is when you run...for example, CP at the present time is experimenting with 30,000-tonne trains. Just prior to a month ago, we thought--and we still think so, to be honest with you--that a 20,000-tonne train is a heavy train. That is a very huge train. They were combining in Kenora, just east of Winnipeg, over the last week or 10 days two 15,000-tonne trains and running them over the track. That would be more of a challenge. There would be different engineering challenges to maintaining high-speed rail, but I don't think they would be anywhere near the challenges there are to maintaining track where you're running even 15,000-tonne trains. Back in the eighties, if we had a 5,000- or 6,000-tonne train, that was a big train. Generally speaking, they kept them below 6,000 feet.
So there's more of a challenge there than there is with the high-speed trains. I think once you build the track and you get the trains running, there shouldn't be as much of a problem maintaining the track.
