I notice that the diagram you posted shows the pocket track we were just discussing with full access from both directions.

I noticed that aswell, presumably that was the original intention but wasn't viable for one reason or another. I'm guessing because it would have required closing both tracks.

Tire testing for braking in heavy rain

Seems odd you would do this kind of thing that close to a curb/fence even if they know what they are doing.

Well, the ground is flat, there's nothing that's going to magically change the forward momentum of the bus and push it into the fence.

Ive heard that they are in fact retaining the existing turnouts and adding two to give full movement as the diagram in jollyburger’s post shows. The video TL included is simply showing the usual train movements and simply doesn't include the turnouts not used.

Stainer clout stolen again!

The video has good answers for the questions previously asked in this thread.

This is how the structural concrete/steel work is broken down.

The Pocket Track, Tie-in Structure and Flyover Scope includes selective demolition of existing pocket track slabs, parapets and pier caps, selective concrete cutting and coring on slabs and parapets, lowering of existing precast guideway girders, supply and installation of the new guideway piers, pier caps, precast/steel girders, precast deck panels, bridge bearings, track slabs, and parapets. A project brief with preliminary site plans is included to illustrate the intent of the overall project.

Package #1: Structural Concrete Related Works:
• TP 02-05 Demolition
• TP 02-06 Concrete Cutting & Coring
• TP 02-07 CIP Concrete Formwork
• TP 02-08 Precast Concrete Girder and Deck Panel Supply

Looking at this diagram, the fly-over wasn't going to come for the end of the pocket track as I once thought. This diagram is in line with the current video released.

I think the originl slide showed the fly over from the pocket track hence the term.

This diagram and the current video show no fly over. it will all be level at the guideway level possibly rising to keep CP happy. and trains clear of the 2 level freight trains.

Just my Opinion.

[madog222]

I'm pretty sure thet current design has always been the plan, perhaps some misinterpreted 'flyover' to mean of the Skytrain tracks. It will always be an extremely low use line compared to the adjacent configuration at Lougheed, no need for grade separation.

If only Braid would use the land to build a massive park and ride

[officedweller]

There has to be a flyover to cross (fly over) the CP tracks.

The RFQ diagram that Jollyburger posted is consistent with the Translink video graphics (if they just show movements).
The RFQ diagram shows a double track flyover.
The Translink graphic shows double tracks intersecting with the mainline from the yard.

I'm not quite sure how that would jive with the Province's Transit-Oriented Development requirements.

[jollyburger]

The flyover has to also clear that parking lot so I guess that gives a rough idea on how low/high it will be at that point. Most of the overpasses west of here look pretty low (like the Highway 1 crossing) so I doubt they can even fit double deckers in this section.

Apparently Translink has opted for 6 additional Mark V trains.

Alstom will supply 6 additional Vancouver SkyTrain Mark V trains

Alstom will supply 6 additional SkyTrain Mark V trains to TransLink
The contract is valued around €86 million (CA$123 million)
Each train, composed of 5 railcars, is designed and manufactured in Canada

28 May 2024 – Alstom, global leader in smart and sustainable mobility, will supply 6 additional SkyTrain Mark V trains (30 railcars) to TransLink in Vancouver, British Columbia, under a contract valued around €86 million (CA$123 million) *.

“We’re proud and honoured of the continued confidence of TransLink,” says Michael Keroullé, President & CEO Alstom Americas. “This additional order of our made-in-Canada vehicles, specifically designed for Vancouver SkyTrain, will help improve daily commutes in the Vancouver Greater Area.”

The Mark V design features consist of five-car sets, all internally open-ended with walk-through carriages. They have mostly forward-facing seating and include more space for bikes, luggage, and leaning pads. The new digital interior information displays will provide riders with improved onboard transit alerts. Strip indicator lights at the doors will assist people who have hearing loss by flashing when doors close, fault warnings are issued, or when emergency brakes are deployed. The Mark V trains will operate with door chimes and on-train announcements to assist customers who are visually impaired.

Alstom is currently supplying 41 Mark V trains (205 railcars) to TransLink. The first trains have been delivered to Vancouver in December 2023. These are designed, manufactured, and tested in Canada at Alstom’s facilities in Kingston, ON, La Pocatière and Saint-Bruno-de-Montarville, QC.

With 4,600 highly-skilled Canadian employees, Alstom is the only global rail mobility manufacturer to have production facilities in the country.

Guess testing is going well?

These should be the 30 cars announced in 2021 as part of the SLS project.

I wonder if they'll ever get around to installing leaning pads on the Mark IV trains - it seems like a simple enough thing to do. I vaguely rem it being in early images and yet none of the Mark IV trains seem to have them.

Regulatory capture has gone so far that they're boasting about their monopoly status.

Good catch. Makes sense.
