Calgary's SE BRT for Max Purple, if you prefer the marketing, progressing towards November 19, 2018 opening. This webcam does have a timelapse video you can watch too.

Whats the progress like in Edmonton?

And Rideau. With the scaffolding gone, it's looking good.

Can't wait to ride the Confederation Line when I'm in Ottawa in 2020 for the Bingham Cup!

Those stations are looking friggin awesome! Congrats on such a good looking RT project.

Speaking of dope ass rapid transit projects, Calgary Transit has now unveiled that they are looking at a single-bored tunnel for the 4.5 kilometer Green Line tunnel. The tracks would be stacked rather than side by side. The rationale for this is that this form of construction is much better for loose soils - which Calgary is plagued with - and for minimizing impacts at ground level during construction.

Nice to see progress on the Green Line! Pretty cool to have another Vancouver style tunnel.

Side note, my girlfriend was asking the other day how the LRT in Ottawa might do in increment weather and I was as hoping to ask the Alberta forumers. How do the overhead wires, tracks and trains preform during snow storms, ice storms and other extreme weather? Do your networks ever shut down because of those sorts of conditions? Are the overhead wires ever damaged?

milomilo · #**11351** Posted **Oct 7, 2018, 3:41 PM**

The LRT is pretty resilient to snow and cold, I think there are heated switches, but the overhead wiring seems to do fine, I've never known any issues with that. But we don't get ice storms and our snow is very dry so doesn't stick to the lines.

CityTech · #**11352** Posted **Oct 7, 2018, 3:57 PM**

The Confederation Line has heated switches.

Ottawa and the Alberta cities aren't necessarily good analogues for weather, though. Ottawa doesn't get as cold as Edmonton (-30C is actually very rare in Ottawa, it happens maybe once or twice a decade, whereas in Edmonton it's common enough during cold snaps) so temperature isn't as much of a concern, but Ottawa has lots of freezing rain and ice storms which the Alberta cities don't really have. So it creates a different set of climate challenges.

MalcolmTucker · #**11353** Posted **Oct 7, 2018, 4:02 PM**

Yeah, as long as the crossovers have pretty heavy duty heaters it should be fine. In Calgary with interlining you sometimes have track maintenance people standing by the switches to make sure things stay in operating shape on exceptionally cold days.

For Ottawa I’d be more worried about the signal/automated control system. Edmonton got hung up as the system they bought for their recent north extension counted wheel rotation to accurately show vehicle possition, but in the cold and wet, and ‘extreme’ grades the LRT supports, wheels slipped and the system was unreliable. Thales claims they have found a fix now, and the city will be testing it over the next few months.

Really? That seems a pretty antiquated way of tracking positions compared to newfangled GPS and transponders?

Reecemartin · #**11355** Posted **Oct 7, 2018, 5:05 PM**

I've gotta say the Confederation Line is easily the most beautiful RT line in Canada. Pretty impressive to see how much progress is being made cross country in general.

Speedometers are still pretty standard in vehicles and the response time for GPS/Transponders is poor enough that they wouldn't be able to work that way. Once you have a wheel rotation counter, you might as well use it for other things too.

But... they can work that way?

If tracking vehicle position was going to be important to the line's operation, why would you base it on something that is obviously going to be unreliable?
