Danforth Line 2 Scarborough Subway Extension

[Kyle Campbell]

I'm hoping that they'll at least rough-in the stations they dropped. It will become very obvious (though it's pretty blindingly obvious now) that people will demand in-fill stations a few years after they realize there's a subway right under their feet that they have to travel kilometers to the nearest station.

is there any tangible savings between roughing in and building? I think the cost of doing it in the future would be massive compared to just building today.

They should be designing them and building them now as most importantly they'll never be cheaper, the cost differential is likely not significant from the rough in.

As has been mentioned many times before, roughing is nearly as expensive as building the entire station. When you rough in, you’ve already paid to build just about all of the internal structural elements.

Of course, you wouldn't have to rough in Sheppard-McCowan Station with the current alignment

Lawrence East and Eglinton-Danforth on the other hand...

Yes it negates a lot of the "savings" but I was thinking more operationally. Adding an in-fill station later will result in major service disruptions

I wonder if anyone from China reads this thread and laughs. Probably not. But they should!

Are they even allowed to see it?

Just for reference what would be the definition of a rough-in that people have in mind? A cut and cover station box is obviously very expensive, but there's other options.

Probably something like North York Centre wherein the station box was roughed in but they only needed to knock down a few walls trackside and build the actual station to make it viable. There is also the Willowdale Station option, make provisions for the station in the future but don't do much else.

Not unlike Toronto, where we won’t be allowed to see the revised cost estimates for SSE before the next election, even though those estimates will have been available.

Something like the willowdale option was what I was thinking of

Honestly though, I am curious as to just how expensive it would be to expropriate a strip along the existing RT alignment that would be wide enough to run subways on.

The fact that this is even a question that needs to be seriously asked because it likely is cheaper at this point to expropriate the entire corridor (in an era where Toronto housing prices have skyrocketed), should speak volumes about the problem of cost escalation of infrastructure in this country.

Try anyone from the rest of the world not named NYC.

Subways don't cost this much in either Europe or South American countries with expanding subway systems in metro areas.

If the reported cost is too high one can only hope they come up with a cheaper above ground in some places version.

Did anyone happen to save a copy of the Environmental Project Report for SSE? Or whatever it was called... was the last major document that showed things like a 2D cross-section of the extension. What's the deal with the City hosting it for a month, then completely expunging it from the universe. Is that a normal practice?

Either way SSE costs seem way out of line. Hard to argue with what an engineer says, but I mean c'mon. One station. You'd think with that cost there's a mountain range between Vic Park and SC.

Are you asking for the Business Case?

I got two. One dated to June 2016, and the update dated to February 2017. I also have the Metrolinx subway feasibility report from 2013.

I wish UT had some kind of public document archive. The amount of transit-related documents floating around is staggering, and their presence on the internet is fragile.
