The advantage to using modern "Intermediate Capacity" system like that on the REM has several potential advantages:
Yeah, and REM is the 'largest construction project in Canada' at this time, so its visibility is very high, but of course, Van and Edmonton also offer precedents. What seems clear is that it won't be anything that the TTC is presently using. There's real irony in the SRT being the most advanced TTC heavier rail vehicle, and it's on its death bed. REM is going to come up a lot in discussion on this.
I am a huge proponent of elevated, but even don't think it will work through the core.
Totally agreed. It goes without saying, albeit I've got to leave a crack open there, as other cities are doing it in their cores.
I still think cut-and-cover is the answer.
I may disagree with what's apparent, but to not revisit it would be a massive mistake. Deep tunnelling has been sold to us as the only option. With the cock-up this has been from day one, I'm now ready to question anything and everything.
But to be different from the 50's, use pre-cast concrete and other rapid construction techniques for the construction.
This is an excellent point. You see this in trenching operations. The underlying soil conditions must be appropriate though, but again agree, alternatives must be considered. Perhaps less boring used only where unavoidable and c and c in other spots might be doable, albeit that might be a false economy unless done right. To be continued...
Once the DRL gets north of Don Valley, elevated is a definite option.
Not only an option, but a incentive to get some real distance for minimal cost. Some of the locals won't like it, but if they're paying, that alone changes their outlook.
Perhaps if you tried limiting you posts to one or two simple sentence and no more than one relevant (brief) quote, with an underlying link for those that want to read further.
Just because you can't read? You'll notice no-one else had a problem with it, and you continually have problems with others on exactly this point, as
@Northern Light can readily attest.
