It’s a bit of a weird one for him to (n o pun intended) rail against. I suspect some of the narrative will be east vs west stuff, why are the laurentian elites getting a fancy train etc… And obviously it’ll get contrasted to the lack of any pipeline project so long as that remains the case.
And considering support for passenger rail, including high-speed rail, is part of the CPC policy book.
The problem with on-time reliability of the current VIA lakeshore service is it subservient to CN freight. Since that is their money maker, CN is not going to agree to give passenger trains priority. We can't compare this to European mixed passenger-freight rail because the amount of tonnage we move compared to Europe is orders of magnitude higher.
They can't run high-speed rail in the current CN corridor, even if there was room - which there isn't - because the alignment of the corridor (curves grades, clearances, etc.) doesn't support high-speed trains, so even if they could expropriate the corridor wider, it still wouldn't work. Even without that, expropriation along or adjacent to the CN corridor would be horribly expensive. Towns and cities have grown up along the tracks as they have in just about every country. That's about as looney as some politicians suggesting that it should be run down the 401.
Unless it was a separate right-of-way, it is still going to be a tenant operation in a corridor owned by CN and is still going to be constrained by their operation rules. Both CN and CPKC are adamantly opposed to electrification of their corridors. Neither railway will idly sit by and accept any change or imposition that threatens their profitability.
If ALTO goes with their proposed northern alignment (very roughly following the former Ontario-Quebec Railway right-of-way), the good news is the area is much less densely populated; the bad news is the area is much less densely populated. Regardless, the point of ALTO is not to serve local needs; it is to improve travel between large population centres. 'They have promised (ya, I know) that local VIA service will continue along the CN corridor.
To hear the people howling about this, one wonders how the 401 or Seaway could ever have been built today.
