I'd say the similarities are that they both have issues. In competitive line rates, as they exist today, essentially the railways don't compete against one another. That's why it's been an ineffective remedy, and it's been little used over the last 20 or 25 years.
Long-haul interswitching, for the mining sector, just because so many areas essentially are geographically barred.... This morning we even had a discussion trying to figure out who in the mining industry might be able to use it. It's not at all clear to us. Certainly, anyone operating in British Columbia, in the entire province, is barred from using long-haul interswitching as it's defined. That's quite astonishing, but in fact, that's the way we interpret it. With respect to areas in the east, in Ontario or Quebec, because of the corridor definition between Windsor and Quebec City, I can't figure out who might actually be able to use the thing. To be candid with you, unless that geographic piece is fixed, I don't know, at least in mining, who might even use it. Therefore, I haven't spent a lot of time thinking about it.
