Calgary Regional Rail Transit

It's more like HSR is just a "might as well" if they're going to build a new alignment separate from CPKC anyways

I also wouldn't think of a separate corridor as needing to be one of HSR or the other, not HSR. It can be both direct and also stop at every stop along the way. In your own corridor you are your only capacity constraint. Obviously the line will need to be twinned at points to avoid colliding with oncoming trains.

Does it cost that much more to add a third track and a basic stop (not a grand central) in Cochrane, and Highway 40 and Canmore? We have to remember, we are not inventing this, other places have done this, and on much more difficult terrain.

And if you have a consistent technology across your regional and HSR you have all the benefits of using single technologies on trains from Calgary to Banff, Calgary to Edmonton, Calgary to Airdrie, Calgary to Okotoks/High River, etc.

There needs to be more study, but HSR have stricter requirements for curves, grade changes, so it's not as simple as change the trains, the route may be very different. Not to mention the tighter tolerance for rail and higher maintenance requirements.

Their own corridor is pretty important for either. And adding stops are very expensive for HSR, it's why many cities that build it often have a different HSR stop than conventional rail stop, because it's very hard for HSR to curve into the city and exit back to its ROW.

In my experience on HSR, conventional, HSR and even LRT are at the same stop and share platforms. No matter the train it''ll go slower through congested areas whether it is going in a straight line or not and whether it is stopping or not.

Really? Not trying to be sarcastic but genuinely curious where that is happening. When I've taken the HSR in Europe (Eurostar and Renfe), Asia (Korea, Japan, Taiwan, and China) it's always been dedicated tracks and platforms. Even when they're in the same station, it's usually like a separate wing or addition that's a short walk from the main station. Especially older stations where the HSR was added years later.

Fair enough, in Italy I walked off a high-speed train and switched platforms on to a commuter style train. We were going from Florence to Cinque Terre. And just a few months ago in France I switched platforms in the same station to go from a High-Speed train to light rail in Nice. Granted in both cases the High-Speed train was not travelling quickly and was essentially a large and long commuter train.

I think Brightline West is the closest analogue to what "HSR" would be like to Banff
A high speed trainset might also have better performance on grades
