Isn't it better if the station platform is in the middle between the two tracks? Why don't they do that?

It's more expensive to separate the guideway into 2 single guideways (each with their own support columns) for a centre platform
- even after accounting for extra elevators and escalators for 2 side platforms.

With the side platforms, the segmental guideway just runs through as usual.

Out of curiosity on my way to Lougheed this afternoon, I diverted onto Cecile Drive this to see the tunnel grouting work. It is a much bigger worksite than I expected, having previously only glimpsed it through the woods from Clarke Hill. Drill/injection rig, multiple tanks, trucks, pumps, etc. Makes me wonder if they are using directional drilling methods to cement a continuous segment of the tunnel route instead of just a "plug" above the current location of the TBM.

Also, I expect they might do something similar farther south in the middle of Clarke Road where they drilled earlier in the fall and established some sort of well cap about 30 cm in diameter (i.e. NOT a typical geotechnical test hole.)

If nobody futzs with the webcam, there will be a nice time-lapse of how the beams are assembled, and how the gantry moves between the columns.

Unfortunately, with these government projects and their webcams, when there is a part of the project that you would really like to see on the webcam, the cameras will be down for the majority of the job you would like to follow. It happened at least a half a dozen times on the Port Mann project.

Photo I found of the at-grade guideway running alongside Clarke Street in Port Moody (west of Moody Centre Station), from a piece on the Vancouver Sun on the 0.5% sales tax increase:

It sure is a sight for sore eyes to see all these updates (This project along with Vancouver's Turn have been soooo long in the making, and they are finally coming together).

Again, I am so happy that the Evergreen Line was not built as a separate at grade LRT project. Out of all the non-sense that is the one delay I can accept (switching it back to skytrain).

If it was a grade LRT Project I wonder how much more the tunnel would have cost. It would need to be either larger to accommodate the added height of the vehicles or twinned.

Having it fully integrate into the existing SkyTrain was definitely the right decision. I still wish it would have followed the originally intended corridor along Ioco and Guildford Way. It would have done a better job of servicing the existing high density core of Port Moody and allowed for easy extension further into Port Coquitlam instead of requiring a spur line as it stands.

In the end with the tunnel required and the two short elevated sections (connecting to Lougheed station and one over Lougheed Highway in Coquitlam) the LRT project became only around 100 to 200 million dollars less than the skytrain project being built now.

Why are the tracks so far apart? That's got to be at least double the minimum required distance, even on a curve.

Edit: oh, duh, that's just leaving a center platform station.

Thanks for the info

Port Moody heavily rejected SkyTrain in a 2004 referendum (something like 74% voted against.) It was an elevated trackway that most residents didn't want. Most preferred LRT on St. Johns Street or at grade along the CPR tracks.

I went to the funny white spot.

Great view of the catwalks - but the image needs resizing

It's actually west of that. There's the station, then a section with a pocket track in the middle. Then there is the widely separated section you see until the tracks draw together. I suppose since this is all at grade there was no rush to jerk the tracks back to parallel. Perhaps they were thinking ahead about the best speed design.

As someone who lives in the area, SkyTrain does not make sense for Guildford whatsoever. There are no real destinations along that corridor. LRT might have been doable but SD43 at a minimum would have had a fit at it passing so close to two schools.

I think we can agree to disagree on this one. I also live in the area and fully believe areas like PoMo City Hall/Rec Centre/Library, NewPort, Eagle Ridge Hospital would definitely have benefited from such an alignment. 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.

Total agree. I've been turning around in my head how the line will possibly turn around given its northward orientation at Lafarge-Douglas with a lake right next to it. Perhaps a single-platform 180 degree turnaround, as they might do if extending the YVR Canada line portion to Brighouse?

Simple answer. The line won't turn around. They designed Coquitlam Central Station to allow for an extension via a spur towards PoCo. It would be similar to how the Canada Line is set up with 1/2 trains running to PoCo and 1/2 trains (or some other ratio) running to Lafarge Lake. Unfortunate.
