I'll clarify, it's not physically impossible. But consider that among the faster Chinese HSRs that top out at 350, not Alto's 300, only about 8-9 lines can hit those average speeds. And that's on mostly elevated viaducts that can better neutralize human and geographic constraints. Alto will not be mostly on elevated viaducts. For 8 to 9 lines averaging >=250km/h, that's among ~50 total lines, including many that top out at 250 to 300. Afaik not a single Chinese HSR that tops out 300 can hit 250km/h terminus to terminus, except for express and non-stops. 500km is not the route length for TO-OTT-MTL.It may be wishful thinking that the high speed service is maintained for the entire route except for stations. Does not mean it cannot be done. Once they release the plans, we can see what they are doing. It is just like how we all can agree that the route will not follow the exact and entirety of the Havelock Sub.
Consider that a 300km/h top speed train takes ~40km and 15 minutes total for two acceleration-decelerations from Toronto to Ottawa to Montreal, that leaves you with 1:45 to cover 510-560 km. That would imply an average speed of 291 to 320 km/h. I am assuming the total distance travelled TO-OTT-MTL to be 550-600km. That's not factoring in a dwell time for Ottawa and slow sections near stations.
So for all intents and purposes, your dreams of 2 hours TO-MTL is wishful thinking. It's admirable to have lofty goals, but when you look at the practical considerations, it's just not feasible in Alto's case.
