I'd just like to say that I've been lurking in the shadows for this entire thread and have done much research on this subject over the years, and have come to the conclusion that Skytrain is the best option for this route. Despite the high cost, Skytrain will provide a backbone to Vancouver's transit system for generations to come, and begin to tie the central part of the city into a
simple to use high-capacity / high-frequency network like those found in many other large cities around the world. I strongly believe that while it is honorable and eventually regionally important to build the Evergreen line (Disclaimer: I grew up in the Tri-Cities) Metro Vancouver should continue the push to build a further concentrated metro/LRT network in the city centre, where it will become a part of a tightly-integrated system, rather than just a spur on the commuter trail.
Ground level LRT has its place, but Broadway simply isn't it. (Espcially considering what's already in place and the reality of building LRT on Broadway, and then of course that whole final product/capacity issue that seems to be a hot topic for discussion.)
I've done my best to spread the word about the Skytrain to UBC facebook group. I rode the B-line from Main to UBC for a year, and compared to taking a metro, it's a pretty miserable experience. Especially in the rain...start/stop, humid and barfy.
Just throwing this into the mix, and I know it's more of a transit fantasy type thing, but once Skytrain gets built along B'way to UBC then what next? Something to think about
: I believe a high capacity and fast metro/skytrain line down Hastings from Renfrew-ish to Georgia, continuing down Georgia to Denman, down Denman to Davie, down Davie, and then across False creek to meet up with the Millenium UBC line near Burrard/Arbutus would help tie East and West together better, give people further out better access to Stanley Park/beaches, and provide the super-high-density West End with an immediate and meaningful transit option. The density of these areas could easily support this, and the overall downtown transit flow would increase immensely with more stations and more routes downtown.
Anyhow, that's just my rambling/dreaming, and it'd probably cost way too much, but whatever. Keep up the good work fellas. Seriously, Vancouver needs more positive outlookers willing to sift through the BS and help let people see the common sense that comes with thinking down the road...er, rails.
