I just want to emphasize the point I made at the outset, and which you've acknowledged. This is a very expensive process. The vast majority of those who use the railways can't get that or can't afford to do that. That's why the other measures we're all proposing, whether they deal with data or long-haul interswitching and so on, are so important. We don't want to have to get to.... I mean, this is a last resort. Teck, I think, is the biggest customer of the railways in the country. Is that not right? We don't want to have to get to that point. If we do, we want it to work well.
The other measures we're talking about are to ensure that the system actually works such that we don't actually have to get there in the first place.
