Millennium Line - Evergreen Extension | Completed

Perhaps a station near Lansdowne Dr with some rezoning would promote some additional high density development.

Instead the line goes essentially straight along the Barnet from Ioco to Pinetree without any stops, future stops, or need for future stops since its light industrial.

Port Moody would have been better served with a route that followed the 97B more closely. Coquitlam could do some rezoning and add density, and PoCo could easier (and more likely) be served in the future with an extension of Evergreen instead of a spur.

It should be noted that there is a potential future station location at Falcon.
I agree it's regrettable that the tour got changed.
However, For all we know, there will be massive redevelopment from Inlet Centre to Coquitlam Central all along the Barnet Highway. There can still be whatever bus service is needed on Guilford, and it will still connect to multiple stations.

True, redevelopment is possible. The property sizes are in general considerably larger along that route than Guilford. Of course that means loosing more light industrial in the area. A valuable resource for jobs and business taxes.

So stations at Queens and Falcon are still possible. I suspect Cameron is no longer possible.

Cameron is definitely not possible. They would have had to raise the height of the track in order to build the station there which they didn't do.

Are you guys talking about a potential station at Cameron and North Road? 'Cause that seems somewhat redundant to me given the proximity to Lougheed. Rapid transit lines should generally avoid having stations spaced too closely together.

Yes but given the incline up North Road and the density added at that intersection, it makes sense. Well, made sense before they decided to not raise the height of the guideway to accommodate a center of the road station.

I could see a lot of development along Barnet Highway.
Remember that Coquitlam is supposed to be a secondary "suburban downtown core" for the region, like Surrey Central is supposed to be (i.e. not just a typical regional town centre). Surrey is just more advanced in the process (maybe because it got SkyTrain earlier).

Surrey Central will the suburban downtown south of the Fraser River (drawing commuters from the Langleys and Abbotsford), and
Coquitlam will be the suburban downtown core north of the Fraser River (drawing commuters from Pitt Meadows, Maple Ridge and Mission)

So in the same way that Surrey Central will have rapid transit branches to Guildford, Langley and Newton,
Coquitlam will also have rapid transit branches to Burke Mountain(?) and Pitt Meadows/Maple Ridge.

...
"The government was prepared to cover the costs exceeding $3 million, if Burnaby paid the initial $3 million to modify the guideway to make provision for a future station. Burnaby countered by asking that the initial $3 million be shared with the government of B.C. An agreement was not reached. Subsequently, the contract was awarded and construction is now underway."

Corrigan could not be reached for comment before the NewsLeader's deadline.

Coun. Colleen Jordan said on Monday that the province simply "weren't willing to come up with any money from the provincial side."

So with the province insisting Burnaby pay all of the first $3 million instead of splitting the cost, its refusal to prepare for a future station came down to a disagreement over $1.5 million.
...

Yeah - Corrigan was being a jerk wrt Highway 1 and asks for a favour from the Province - like that would have happened!

Also remember that the future cost of a station would have been high as well, because it would have required a mezzanine and a cantilevered structure extending out one each side of the guideway over the roadway like Brentwood Station.

That was a consequence of Burnaby and Coquitlam refusing to allow the guideway to sit on either of their sides of the municipal boundary.

If the guideway had been on the Coquitlam side or the Burnaby side, a cheap side of the road station design like Lincoln Station would have been possible.

So for that first pic - do they just rotate the cutter head to use a new unworn face?
i.e. given the 4 point attachment, does each cutter head have 4 "cutting faces"?

So glad our tunneling is going much better than our neighbours to the south:

Although there are probably some lessons to be learned in there for tunneling under more urban areas, like Broadway.

[officedweller]

That's also because their cutter head is, I think, the world's largest.
That's what probably caused the seals on the cutter to fail.
Even being a dual width tunnel, ours is much smaller.

So far as I can tell, this heckuva beam is the reason the tracks are so far apart west of Moody station and the pocket track. With that beam, Evergreen could not be accommodated in the space between existing bridge columns (the space occupied by the previous roadway access to WCE parking lot.)

The most unfortunate consequence of this is that there is now not enough space under the overpass for a bike route from the Evergreen station and parking lot to the north side of Clarke street. Any bike route will now have to cross the difficult intersection of Clarke and Moody at the south end of the overpass.

I'm surprised to see the "after" cutter actually FLATTENED.

These cutters are supposed to rotate on their axis (the brass center) as they are pressed against the rock face. They operate against rock the same way a glass cutter wheel works on glass - it doesn't break the glass, but rolls on the surface & etches a weakness that can be exploited (glass will break along the weak tracing, as will rock)

Seeing the cutter wheel flattened (and I'd guess most of the cutters were the same) makes me wonder what caused the cutter wheels to jam while breaking the rocks.

Something to keep busy during the dull holidays this week.

So Bertha has been stuck for a year?
heads gonna roll.

Yeah, that's what I'd think, too.

I assume they do roll until they eventually become out of round and can't overcome a flat spot which in turn results in that side of the cutter grinding away.

Construction update:

Looks like they'll be testing as of the beginning of 2016. Early open maybe, like the Canada Line? Maybe spring 2016?

[officedweller]

Thanks!

How about this tidbit:

New cars are also coming this summer, but likely they will be introduced first on the rest of the line.

6 months of testing from early 2016 puts opening at mid-2016 -- late summer?
Just in time for back to school and back to work.


Unless the tunnel is late being finished.
end -to- end testing can't be done without tunnel completion.

Exactly in the timeframe from when the Expo Line was completed 30 years ago. Classy.

I vaguely remember the completion date agreed upon was being specific, which is July 29, 2016. Meaning if EGRT finishes before that date, then its good, and they may even get a bonus. But if they are late after that date, then I think they get some kind of penalty. Maybe someone can dig up the old documents to confirm as it has been a few years already....
