Thank you. I appreciate that you're here on behalf of your city, and you're doing a great job. Congratulations.
I'm here speaking for my constituents, and I think my concern is the huge overall infrastructure cost. At the same time, it takes vision, and sometimes those costs have to be incurred. I don't think any one of us wants to stand in the way of progress.
To Mr. McSweeney. We did have some other witnesses who talked about the standards that would have to be established in Canada for the actual rail for high-speed rail lines. My concern is, has the research gone into cement so we know it can withstand...? I know we talked about weather. This is a huge issue. Can cement withstand not just the weather but the weight, the speed? We've been told that this research has not been done.
