Sounds good on paper, but in reality you have to combine long-distance with proper station spacing. Haney
Mission–Port Haney averages ~79km/h but the stations are 25km apart.
Port Moody–Waterfront averages ~53km/h on ~22km of track.
The whole 69km line averages 55km/h when you account for all the stops and if you only count stations in Metro Vancouver, it averages 47 km/h.
Compare that to:
The Expo Line:
40 minute ride over 28.5km
Averages
~43km/h
Makes 19 stops
The M-Line:
36 minute ride over 25.5 km
Averages
43km/h
Makes 16 stops
The Surrey-Langley Extension:
22 minute ride (projected) over 16km
Averages
44km/h
Makes 8 stops
Regular trains take time to get up to speed and decelerate... and one of the key advantages of SkyTrain is its acceleration profile.

Also, Skytrain tracks, if put on the ground, form an impenetrable 'wall' due to the 3rd electrified rail, requiring the entire thing to be elevated.

I don't disagree. It's only suitable to be ground-running along certain corridors... much like Highways. The YVR section is a good example.

Realistically, I'm a big fan of tram-train as a WCE-style express system for this reason. The only issue is that you either need specialized cars (like https://railway-news.com/aeroliner30...great-britain/, or BART), or squeeze into conventional tram-trains if you want good capacity without having most people stand (not great for a long-distance train). So the trains are going to be more expensive.

Oh, I'm a HUGE fan of Regional Rail, don't get me wrong... I just don't think there are many corridors in Vancouver that are suitable for it. Ideally, I'd LOVE to see the Arbutus corridor used for rail, but where would it terminate on the Vancouver side? There's nowhere for it to go.
