So I actually did briefly look at that site. It would have 7 properties impacted which is 3 more than the other site. The total assessed value is $53.3 million with 90% of that being Land Cost. It is 8.4 ha, but, the site would be long an thin and might not actually work from an OMC design point (it's only 140m wide. In comparison the other site is 200m wide). You might have to get creative and/or limit what the site can do.
I thought it would be more ideal for OMC to have long and straight parallel tracks. This would reduce track and wheel wear and tear, as well as minimize wasted space due to curves. For instance, Edmonds OMC have quite a few wasted spaces between tracks, especially on the curve at the outer edge of the facility. On the other hand, the new Coquitlam OMC3A managed to squeeze in 3 parallel tracks to fit 26 cars in an area that's actually quite long and narrow...

From the cost estimate:


I don't think "at Fleetwood" would fit within the redated space... but "at Langley" would? What about "at Clayton"? "at Surrey"?

Also, any land we discussed that would fit the requirements..?

I'm not sure why the OMC would need to be built anywhere on the surrey - langley line at all. The real need seems to be adding workshop space for maintaining the expanding fleet of vehicles. That can happen anywhere on the system. When both the Langley and Broadway (to Arbutus) extensions are built, then the farthest station from the Edmonds OMC will be Arbutus, not Langley City. If anything a more central OMC would serve the system better. Scott Road is closer to the Millenium Line than Langley City, so doesn't that make it better? It's also closer to any future L line or UBC line extension or expo line extension on Hastings.

In fact I think they could consider a new OMC in Coquitlam at Falcon Drive by expanding the storage facility that is already there.

I think they're worried about a breakdown on the Expo that could cut off one end of the Fraser from another.

I think "in Surrey" would fit in the redacted space.
I'm thinking that a new OMC would have a shed at least long enough for a 4--car MKIII train and probably a 5-car MKIII train.
Is the Edmonds shed long enough for a full 4-car MKIII train?

….You might be onto something. Extending it to the airport could even be, dare I say, building for the future?

I'm assuming that this future is sometime after the next turn of the century - Langley Regional Airport is currently a series of flying schools and the smallest air museum I know of.

If they get too close to the airport then they'll have to deal with the height restrictions. For an example of the impact of these restrictions look no further than the traffic lights at the intersection of 216th St and 56th Ave, at the northeast corner of the airport. They're the most stunted traffic lights I've seen anywhere.

Langley Regional isn't the prize. Langley Memorial, WC Blaire, and LSS are.

MKIII have the same length as MKII cars.

It has the same problem as adding one in Langley.

Maybe. But there's also not much more space at the existing OMCs to begin with. My guess is that they want to bundle the OMC expansion costs with the Skytrain expansion costs as a tactical move to avoid having to spend the money directly.

Also, the Expo Langley-Surrey Section is never going to be one of the most used parts of the Skytrain network, so they can drip Skytrain Trains into the system without having to worry as much about congestion when adding the trains into the system.

the area is already full of BC Government office. (BC Hydro, BCRTC) so it would seem a natural expansion. although it would probably be moderately costly.

Well there's about 4.1 ha of space to expand north of the existing Edmonds facility, if you remove the existing ped path. Problem is that it'd get to land closer to the Skytrain Station, and thus the center of Edmonds, becoming even more of a black hole than it already is. Though all the area is zoned as Industrial in the Edmonds T. Center Plan.
https://www.burnaby.ca/Assets/city+servi.../community+development/LUM+-+Edmonds.pdf
https://www.burnaby.ca/Assets/city+servi...community+development/LUM+-+Big+Bend.pdf

Another idea is to expand away from the Town Center, towards Big Bend. There's plenty of land there. Much of it is ALR, however. The site below uses some lower-value Park Reserve (the actual name of which I can't find, I may edit this when I go home with the actual name), and land zoned Medium Density Residential, but has yet to be developed (mostly) and is on the outskirts of Edmonds (minimum 15 minutes walking from Edmonds Station). There are a couple existing SFHs, however.

Future Expansions would continue to move south into the ALR and SFH lots on Marine Dr. The site shown above is about 18.27 ha in size.

Waves, any help with this one?

The Scott Road one probably has some problems as it's partially located on the Scott Rd. FTDA, whose borders are KGB, the SRY tracks, and the ridge to the East, and a good 7 minutes walking.

Also, I don't think the size of Edmonds is large enough. As was pointed out below, there's already not enough space in the OMCs (something the size of Edmonds would only be enough for about the current amount stored on the tracks proper), and by the time we actually get to building the OMC, things are going to be worse, not better.

We need TransLink to go big so we can avoid going though this process all over again every time we need to expand the Skytrain network. It'll probably inflate the cost of the Langley Extension, but most of the money is coming from senior governments, and the public has shown to be able to accept the more expensive option that is better on the long-term.

Thus, I would also add Serpentine River Golf, which would buy out the Surrey Golf Course for the OMC. It's technically ALR, but it's unlikely to be converted to agricultural any time soon and was only really allowed due to a loophole- so It's 64.55 ha. Which is really overkill.


Therefore, an alternative: The diagram below is 16.3 Hectares. The rest would become agricultural parkland (like most of the Southlands ALR 'exclusion')


I would also advocate a Murrayville Site, on the 'Special Study' area Newland Golf and Country Club (Langley wants to remove this lot from the ALR, an exclusion that has yet to be granted)


The same rules apply to this area as the Serpentine River Golf Site.

Also, Belmont Farms @ Murrayville:

23.57 ha, all ALR land.


The required ~1.2 km Skytrain Extension past Langley Center:


Note that the extension would require demolition of 2 Downtown Langley Retail buildings. However, demolition of those buildings is required if any extension past Langley Center Station is anticipated, so best to do it now.

The Langley Bypass/208 Station at the end of the line would also still be in the Langley T. Center. A station here could probably be justified by its RE potential alone- it's also 15 minutes away from LSS.

There's also the thing that it could divert some bus traffic away from Langley Center, thus increasing travel speed and turnaround time for the 503 and 560.

It's not really optimal, since it makes it impossible to do all-day service when that ever becomes economical, and probably interfere with track maintenance.

Well, City Hall's not going ahead with the Granville elevated deck mostly because it's too much weight for the centre span. The Port Mann is larger and newer, yes, but I think I'll err on the side of caution until the math comes in proving that a SkyTrain guideway works.
We don't know that.
I thought they were still going with the pedestrian path?

Was it built to carry a SkyTrain? These bridges are often pitched as being "BRT/LRT compatible" (and only those two) by the province, then nothing ever comes of it.
There's the 555, which we can just upgrade to 5-minute peak frequency and convert to using double-articulated (and turn to exclusive bus-only use if congestion gets to that point). I honestly don't see why we would be bothering with a Skytrain Guideway on Port Mann... I guess the stop on 152 St has somewhat of a narrow queuing area, but there's not an enormous amount of space in the area anyways, and the 152 Bus Stop pretty much has to stick around for traffic from Carvloth (and soon Abbotsford and maybe eventually Pibbs, BCIT, and Chilliwack).

Skytrain isn't much heavier than LRT (the type wasn't specified, so saying anything with certainty is... hard.)

Original concept. That's been thrown out for something more practical.

Definitely not, but the guideway is (RRT can't go at-grade on a bridge to my knowledge).

That site is also heavily sloped, with about a 40-meter elevation change from top to bottom. That probably removes it from the potential of being an OMC expansion.

If we're talking Skytrain, then I don't see why it couldn't. LIM technology can handle grades similar to road bridges, it would just be a matter of partitioning the track from everything the other bridge users.

The MKIIs are in married pairs so trains can be divided easily for servicing, whereas the MKIIIs are joined in 4s.
Just wondering whether the existing shed can hold a full length 4 car MKIII train or if it has to be divided up.

Great post.

And yeah, when people call me crazy on these forums; I know that they just don't have vision .

But yeah, uhhh Skytrain to Langley Memorial would make this extension legendary.... Let's build it.

SkyTrain can handle the grade, no doubt - my concern is if the bridge can handle the SkyTrain. Might be a failure of imagination, but I've never heard of an RRT crossing a river without a separate deck.

If you build at Langley Airport just build the line there at grade just like the part at YVR or in Port Moody! Once you pass 56 around [Kodiak Aerospace] have the guideway go above grade again and up the hill towards Murrayville using the Fraser Highway right of way...

Maybe? All I know is that even on the ground, the SkyTrain needs something like this - I'd be happy to discover that for the Port Mann, you can just put a track on a lane and be done with it.

Skytrain is "light" rapid transit. You can see that the bridge deck of the Expo Line's Skybridge in New Westminster is no more substantial than that of the Port Mann. I'm pretty sure that a trainset would weigh less than the worst-case Port Mann design scenario where you've got a deck full of loaded semitrailers stuck in congestion.

But yeah, we have to defer to the engineers for the official answer.

And even if the Port Mann could accomodate Skytrain, they might decide to build a separate bridge anyway. That would retain existing traffic lanes and it wouldn't cost very much because rapid transit bridges are a lot cheaper (the SkyBridge only cost $50 million to build in 2018 dollars).

"Light" is usually meant to refer to capacity (even though they are "intermediate" capacity), not weight of the vehicles.

"Light" Rail vehicles, for example, weigh more than SkyTrain cars because they are designed to withstand impacts from vehicles on shared RoWs.

SkyTrain cars are indeed "light" in weight because they run on exclusive RoWs with less risk of crashes.
