I would also say that Mr. Rowden's point has some merit. It has some merit for other reasons, but even if only for the reason that Alberta is pretty flat, or at least the Calgary-Edmonton route is pretty flat. The most expensive part of building any surface transport facility generally, but for rail in particular, is the tunnelling. For none of the routes that we're talking about or that I focused on, and maybe none at all in Alberta, would you need much tunnelling, so that could very well reduce costs.
I don't claim to be an expert on these costs. I was merely reproducing other costs, costs that I have reviewed fairly carefully, and those are the numbers that other people have used. As I say, I put in my document the most authoritative ones, which are from the International Union of Railways and the California High-Speed Rail Authority.
