Toronto Spadina Subway Extension Emergency Exits | ?m | 1s | TTC | IBI Group

I'm assuming they went with tunneling above Steeles Avenue, is because it would be more likely to snow in Vaughan, to reduce snow problems.

Our subways don't have very many issues with winter weather. Certainly not enough to warrant spending hundreds of millions on tunnelling.

Guess you don't stay in Toronto during the winter. From this link:

Snow build-up on outdoor TTC subway tracks led to 30-minute delays on both major subway lines, spokesperson Jessica Martin said. The exposed tracks have heaters to melt away a moderate amount of snow, but Monday’s snowfall quickly overwhelmed them, requiring staff to clear the tracks manually.

But, in reality you're right. Doesn't happen a lot... until the next snowstorm.

There always seem to be delays or closures following snow storms somewhere along the surface parts of subway (never mind the RT).

30 minutes delays once or twice a decade?

They certainly didn't choose to put those new stations underground because of the weather!

It happens every snow storm. Sometimes, they run shuttle buses between Kennedy and Warden stations. The TTC has also progressively buried parts of the Yonge line around St. Clair station in the past few decades.

It most certain doesn't happen every snow storm. Many a storm I've taken the subway because it's more reliable than surface transport.

Delays or closures happen regularly when we get heavy snow. It's often just for a few hours (not catastrophic), but the weather does affect service.

Well I guess you don't stay in Toronto during the spring, summer and fall.

I mean, literally whenever there's a large amount of rain, water comes flooding into the stations and tunnels, shutting down stations and large sections of the underground subway for hours at a time.

In fact, given the expected increase in Toronto's temperature annual rainfall totals, the TTC should start elevating all the subways, to mitigate flooding.

Delays and closures have happened during heavy snow. Sometimes in heavy snow doesn't happen.

But a simple claim that it happens every storm is clearly false.

And the theory that the extension to Vaughan is all underground because of this is patently absurd.

I wasn't making that claim, but it will help with winter reliability.

Nitpick - the winter problems that we have in winter usually result from extreme cold, not snow. Sometimes when it snows, it's also particularly cold, so the two may compound each other.

There's no need to bury Toronto's lines to solve our winter problems - but - parking all our subway trains out in the open at night is definitely a problem. If something needs to be buried (or enclosed) it's the yards, not the line itself.

One of the deepest stations anywhere is Paris' Magenta station, which has a huge high ceiling. It's so lofty that it doesn't feel like being underground at all. I'm all for making creative use of any headroom that happens because of the method of construction (all of the Eglinton stations will be excavated, will they not?). But if it's going to cost a lot extra to achieve, then I would question why we would do this. The headroom of our existing stations is not objectionable, it just isn't 'pretty'.

For those who ask why it takes so long to get things done here let's put this into perspective. New York's 7 line extension opened yesterday. A one stop, 2.4km extension that cost $2.4 billion US and took seven years to build. They actually had to drop a second station because of massive budget overruns.

To be fair though, it's building in NYC in a built up area - and NYC is probably the worst example to follow given their record of postwar subway expansion.

Agreed. NYC is literally the worst possible place to compare to when it comes to construction projects. Everywhere there on average costs more and takes longer than anywhere else in the world.

Perhaps but they were delayed a year because the elevators didn't work. That had little to do with New York.
