Would they use a Tunnel Boring Machine to get through the concrete or would it be dirt and rock a certain distance east or west of the existing tunnel?

The TBM's cut through the concrete station walls for all the stations .up to Allen Road. Then do it again up to Yonge Street, where they meet the TBM's coming westward.
Um, I think we're getting wires crossed here? This is in reference to the Crosstown, whereas we are talking about the GO trains on the Weston sub?
I'm not sure whether the cost involved with a TBM would be justified for one track. I think there would be some cut-and-cover instead, and restricting of lanes on the 401. It's a bad idea given the traffic situation without restrictions, but it might be the best bad idea we got. The GTS team told me it's just a difficult engineering situation they are still trying to figure out. This stretch of the 401 was built in 1956, and the pilings used to make it are apparently messed up.
That signal bridge looks pretty high and close to the end of the tunnel, I imagine the sightlines are adequate though, it would be a huge screwup is they weren't.

Having overseen some of the design work on the TBMs for the Eglinton Crosstown, I can assure you that you would not use one here. Much more complex machine than is needed, and far too expensive. Those were $16M each.
It is rather bizarre. Though 200 million a year isn't to be sniffed at - not as high as Line 1, but quite impressive given the limited technology they used. The Eglinton line only forecasts 50 million a year, with significantly more capacity than the Canada Line has.Residents of Vancouver are drowning in hatred of Toronto. Just go there--they love to tell you how much they hate us. It's pitiful. The thing is, they don't seem to realize here in Toronto we don't even talk about them.

Oh ... hmm, 200 million would be about 650,000 a day ...and apparently their daily ridership is about 135,000 a day on Wikipedia. So 200 million all-time makes more sense. Hmm, not as impressive - a bit more than double their 99 B-line bus.did i read the wrong article? it seems it is 200 million in 5 1/3 years.

And only 135,000 a day compared to the estimated 170,000 a day on the Eglinton line - which doesn't even go downtown! Not impressive at all.
Not long after reaching its fifth year anniversary this past August, SkyTrain’s Canada Line recorded its 200-millionth passenger sometime sometime on Sunday, November 16.
Yes, it's clear. I looked at it quickly and assumed that on an annual basis simply because otherwise would be well less than 50 million a year would be embarrassingly small for what is essentially a subway line into downtown. But once reading it properly, it's clear that ridership really is that low - only about 40 million a year. Toronto's streetcars alone carry close to 90 million a year!I wasn't guessing....the opening paragraph says:

To be fair, the Eglinton line estimates include Phase 2 to the airport. Though you only have to see the ridership numbers, to see how small a portion that is.Nor, initially, connect to the airport.
