Millennium Line - Evergreen Extension | Completed

[nname]

Its just for a temporary bus loop, since the guideway is going to making a turn on top of the south end of the bus loop.

it's just harder to quantify and point a finger at...

Agreed regarding a switch after the station (avoiding the delay of trains crossing in front of each other) increasing capacity - but given the various crossings at Lougheed, will they ever need/be able to achieve that high an ultimate capacity?

That's a good point. I can't help feeling that Braid/Sapperton are a glitch in the design of the overall network because of the way they split frequency for both lines. I guess one option, which I'm sure would be strongly resisted by some, would be to abandon them or at least severely curtail their service level when it gets to the point that they're the bottleneck.

why would you ever abandon those station?? how would that help the system?

Worst. Idea. Ever.

Both stations are getting anchor developments beside them. ToD is arriving and it is too late to consider whether they were good or bad ideas.

The Millennium train can always wait for an Evergreen train. There should be more than enough time to cross over when the Evergreen train is loading within the station. I think the bottle neck is still at the end of the track.

That's that Chicago did.. to the point they ended up just demolish the line all together...

And.. regarding to Evergreen Line construction, today they are demolishing part of the pre-built platform at Lougheed station, stating from the west side

I'm assuming you are referring to the passenger platform, correct?

Irony much? They destroy one chunk of concrete but not another...?

We want photos.

My comment was actually referring to the Evergreen Line trains crossing in front of themselves to get to the correct platforms at Lougheed (and correcting sides after Lougheed) - i.e. independent of M-Line trains.

It looked to me (vaguely between gaps in the plastic sheeting) that they were only demolishing a portion of the platform, presumably where an escalator of elevator would be at the west end.
They've also started putting up boards of wood along the outer edge of the platform where the glass will eventually go.

From the work on the guideway columns on the existing pillars, it looks like they're not planning to take out that bump on the inbound guideway, and it looks like they might keep it at that height (or higher) for at least the first part of the curve.

Cool! Thanks again for the info, dpogue! Your videos are such a fantastic at showing progress.

Looks like we are indeed getting a dual tunnel like Columbia-Sapperton, not the large single tunnel we all were fawning over.

[GeeCee]

I think that's just a support column.

Furthermore the TBM is 9.84m in width per the previously posted TunnelTalk article: http://www.tunneltalk.com/Evergreen-LRT-...confirms-Caterpillar-as-TBM-supplier.php

Caterpillar will supply a 9.84m diameter mixed face EPBM, plus back up, for excavation of the single-bore tunnel section. Specification calls for ability to withstand pressure up to 5 bar.

That is only the cut and cover portion.

[officedweller]

I suspect it's designed with the wall in the middle because Barnet Hwy will be diverted over top of it for a TBM pit to the west of it.

The picture shows the tunnel under Barnet hwy only. The bored single tunnel is west of Barnet hwy. For a live update go to the evergreen website/ webcam
