That's ok she'll be unhappy until 5 years later when her place has increased in value. That's what happens everywhere. People complain then 5 years after it is built their place goes up by $100,000 and they go "yippy". Well until they see their property tax bill I guess but even then more equity is good.

Yeah the property tax is a problem. Your share of city tax revenue goes up when your house appreciates in value more than that of the average house in the city, and that's exactly what happens to housing near a Skytrain station.

My house is about a 20-minute walk from the Expo Line, which is perfect for me. It's too far away to really impact property prices, but I have no problem walking that distance. And on really crummy days I have two different bus routes I can choose from to get me to or from a Skytrain station.

I saw they set up a huge board outside the project office, and also built the support for two more at the site of Lincoln and Ioco station... Maybe something coming up soon?

[red-paladin]

Hopefully the contract has been signed and they are getting the 'Your tax dollars at work" type signs ready to announce major construction.

Project controller has been hired in the past couple of weeks. Something is coming.

There are a few project signs around here and there.. the one at the office is covered up and has a small platform underneath it, perfect size for a small media event..

Or a pre-election photo op... I think we're going to have wait a couple more months before its 'official.'

The funny thing is James Moore and Mary Polak were suppose to give an Evergreen Line update news release on December 19.

http://www.cbc.ca/news/politics/inside-p...ng-some-news-for-today-jason-kenney.html

On the west coast, James Moore joins BC Transport Minister Mary Polak for a "special announcement" on the "highly anticipated Evergreen Line rapid transit project" in Coquitlam

This news release was cancelled due to that "snow storm"....you know...the same one with the Port Mann ice bombs. We never heard from them since with regards to the Evergreen Line so I guess we will never know what they were going to say. I'm guessing, whatever it was, its probably not important...

[officedweller]

Probably difficult to reschedule a news conference over the holidays, plus Moore probably has to fly out from Ottawa - so hard to find an opening..

So I've found some interesting info regarding the Evergreen Line and its bored tunnel.
The original pre-2008 LRT proposal specified the requirement of a 5.7m diameter tunnel boring machine. [LINK]

This surprises me as it is actually narrower than the 6.1m machine used for the Canada Line [LINK], despite the overhead needed for the electric supply/pantograph.

What it does tell me however is that the tunnels for the ongoing SkyTrain proposal are going to be even narrower than 5.7m (hint hint: key in determining the tunnel width for Broadway subway). I might ask the Evergreen Line office about this, but I doubt they have the info yet as the primary contractor was only recently announced and I'm not sure if the TBM has been purchased yet.

Am I missing something? What pantograph?

[nname]

I doubt the 2007 proposal specified anything.. they were still in the design stage before the project was cancelled.

The Eglinton LRT in Toronto actually uses a TBM with 6.7M diameter...

Referring to the pantograph required for overhead-wire LRT for the previous Evergreen Line proposal

This is random... but while I'm at it searching for statistics, does anyone know where I may obtain access to the 2010 Canadian Public Transit Fact Book? (published by the CUTA)
It is so hard to find T_T

[Zassk]

The SkyTrain cars are smaller in cross-section, yes, so perhaps the tunnel can be narrower... but is there really much savings in a difference of 1m or less diameter on a tunnel boring machine? Surely the main cost is in the distance travelled, which would dictate the amount of upkeep/maintenance required the unit.

[xd_1771]

Price of TBM, amount of land extracted.... there can be a decent savings from minimal TBM diameter.

SkyTrain cars are smaller in width and height thanks to the LIM (LIM brings the train body closer to the ground). This is precisely why LIMs were studied and used for a similar application in Osaka, Japan about the same time the SkyTrain first opened.

Regardless of train width and vehicle height, LRT in a tunnel should usually require much larger tunnels because of the need to accommodate for significant additional overhead for the power delivery (pantograph, wires) compared to a rotary motor metro or linear motor metro with third rail power. This is illustrated well in the Eglinton LRT proposal: a massive 6.5m diameter for each tunnel.

I now realize that the 5.7 value dictated in the Hatch Mott McDonald PDF for the tunnel is pertaining to tunnel size, not necessarily tunnel boring machine size (which might be somewhat bigger) - but that still puts the TBM size at smaller than the one used for Canada Line (considering that on Eglinton LRT, 6.7m TBM is to 6.5m tunnel... therefore I think it's fair to assume that 5.9m TBM is to 5.7m tunnel). I guess the Evergreen Line cars were slated to be very small to help bring the costs down or something? Perhaps it was to use 2.4m LRV offerings (vs 2.65m ART, 3.2m Rotem EMU), but I don't think that addresses the height disrepancy.

Ah, of course - thanks!

Well, its been one month so far. February would be opportune, since they're not actually allowed to announce such things DURING the election campaign (or are they?).

The big EVERGREEN LINE PROJECT signs, and crews not-quite-yet making commuter life hell should be enough to remind people the liberals are building the line.

[KPELLY]

From what I've heard SNC-Lavalin is actually going with a large diameter single tunnel for the Evergreen Line instead of side by side tunnels. The reason being time savings over having to launch the TBM twice, and cost savings over renting/shipping/assembling 2 TBMs. Likely the TBM will be launched from the Port Moody side because going uphill allows water to run out of the tunnel naturally avoiding any need to pump.
