I'm all for elevated systems and I am secretly hoping that Vancouver's Skytrain extension to UBC will elevate westwards after passing Blanca street to save on costs,
but I digress...
One of the biggest problems in Vancouver with elevated lines is that it draws the NIMBYs out from the woodwork with torches and pitchforks. If you thought your NIMBYs were bad now, then just you wait until you propose an elevated line over a high-street to save billions on construction.
I'm not sure how an elevated line handles regular snow. With the very
few snow days we get in Vancouver, our trains do experience delays since our system will detect an "obstruction" on the track. Couple this with the fact that regular drivers are now switching to Skytraining on a snow day, we get pretty regular service disruptions when these super rare snow days happen. Perhaps an angled "hat" on the tracks would make the world of a difference?
To play devil's advocate, I completely agree that having an elevated line directly over busy streets will change the dynamic of a neighbourhood completely, even detrimentally. Therefore elevated rail options aren't right for every location but it sure beats the hell out of having trains mixed with street traffic.
