^ In all the debate about this, I don't recall anyone laying out a clear proposition that there is any sort of win-win possible between freight and passenger. As freight railways have evolved on this continent, it has become more and more true that passenger rail, while desirable in its own right, just gets in the way of the freight operations. And as we've seen out west, constraint in the freight system goes quickly to the nation's breadbasket.... inability to ship grain, potash, and oil is a far more potent political concern than not having enough passenger trains.
There are places where passenger survives because it is quietly underwriting freight operations - but even there, passenger takes a second seat whenever there is a conflict in priorities or interests.
Untangling all that would be a huge pile of work, and even a compromise would satisfy few. So much easier to just build dedicated passenger lines, and be done with it.
