I don't know whether in the past that was done, but maybe I can clarify one thing that's really important. I deal with many infrastructure projects, so let me take this opportunity to present to you a bit of a sequencing of what happens.
This study, for example, which will be done by early next year, is going to be a feasibility study. It's a key study in helping inform the governments as to whether they want to proceed. But after that study, there are significant other studies that have to be completed.
One of them would be an environmental assessment study. We probably have to do one, because this study is going to look at possible routing options. We would have to define what the exact routing is going to be. Just doing that can be quite a challenge, because you have to identify which properties are required. Remember that if you're looking at high-speed, you can't choose the existing rail corridor in place today; you're going to be looking at building a whole new corridor. It could be on the same alignment or not. Those are all costs.
