You're absolutely correct. If you're going to develop high-speed rail, as Mr. Langan defined it, you need a separate rail system. You cannot operate both of them safely at those speeds.
When I was referring to the current VIA project, what's going on there, is that we're producing longer high-speed sidings and whatnot so that we're allowing more efficiency in the use of the existing tracks for both passenger and freight. That is certainly a part of the system, and it will certainly be required no matter what we do with high-speed rail, because you have to have feeder systems.
I only made that observation to demonstrate that there are ways to benefit both parts of the system, and they don't necessarily have to be in pure conflict. But you're absolutely right, sir: if you want to really develop a high-speed rail system it must be separate.
