Not so much from the perspective of those 56 recommendations, sir, but certainly to go any faster than we're going now in our key Toronto-Montreal territory for passenger trains would be a next step up in the class of track. That involves closer tolerances to the geometry and the geometric tolerances at which the track must be maintained.
Yes, we do see challenges there. We're not saying it's insurmountable. But we are saying that at 100 miles an hour we're at the edge of where the industry is worldwide—other than in a few spots on the northeast corridor—in terms of mixing higher-speed passenger trains and lower-speed freight trains. That's why our goal is that it would be on a dedicated corridor. However, we are willing to work with any and all stakeholders, if people want to do a very detailed review of what it would take to go to the next step.
