Its good to know more people are supporting the idea of a High Level streetcar extension, even if they are taking credit for being the one on here bringing up the idea (Yeah, I'm talking about you Big W
) Anyway, yeah there really are two different patterns that LRT can and has been used for. In Edmonton and Calgary, its being used as a Rapid Transit/Commuter Rail type system, while most european cities and of course Toronto and SF as well as other North American cities are using the same technology as stop a block streetcars, which is just as great, but obviously not for moving large masses of people across a city. Thats the beauty of LRT though, it can be both.
For me the first priority should be establishing a city-wide LRT network to move people from the burbs to the downtown and back, and secondly in developing the inner city (Downtown and Strathcona mainly) as vibrant high density live/work/play areas with streetcars.
As for Jasper West, I'd be happy with a mix of street level LRT and subway together like some European cities have done. Have it connect directly to the existing subway like with a quick and temporary cut and cover ramp around Railtown and have it run on the street level for now until the area redevelops itself, and thats when you complete the subway and then perhaps still operate a streetcar on the surface for local movement of traffic, and a below ground network for moving people to and from Oliver and Grandin. Even though the neighbourhood is dense, I still think it has alot of opportunity to become more filled with people, especially along Jasper Avenue itself. For most of the way its still lined with 1 or 2 story commmerical buildings. Illuminada is probably the first project in a long while that has been built with a tower right on Jasper Avenue with retail at its base.
