Just so catchy.

In theory, yes. But I think Skytrain's problems in snow are due to the intrusion detection going off all the time. That problem is due to being driverless though, I would guess.

The Canada Line is all traction motor powered.

[officedweller]

Yeah, the Canada Line is not linear induction.

For the linear induction trains, they also run trains all night when it's snowing to keep the induction strip clear of snow.
There a tight tolerance between the induction strip and the induction motor - something like 1 cm or less (maybe 0.75 cm), so that can get clogged with snow or ice if they aren't diligent.

If that's the reason it seems like they could retrofit the trains to have mini "snow plows" to deal with that, no?

Regardless, it's hardly a problem in our climate. A few days every few years maybe. Perhaps less in the global warming future.

The frequent trains are enough to blow snow off the induction strips.
You can't have anything "scraping" the induction strip, as it could tear one of them up if a screw is loose.

Snow plan is laid out here:

It's also a good reason for making all the stations have a decent roof over the track. If the snow can't set off the track intrusion system, then there would be much less of an issue.

The other part of the snow/ice problem is trees falling on the track, just like with the wind storm last week. Ice buildup tends to bring lots of trees down.

Metro Vancouver board greenlights eight-lane Massey Tunnel replacement

An eight lane immersed tuble tunnel with a dedicated bus lane. It could be worse. It's a bit of a suprise to me, as I thought a bridge had been more or less decided upon; a tunnel ruled out.

Wtf is a metro Vancouver board of directors? Why is this even news. A bunch of people with no actual power endorsed an 8 lane tunnel. Woohoo

You're totally right IMO, but I think this endorsement will creat sort of a "bottom line" or point of reference, and officially rule out a bridge option. IMO should also unclude a RRT tube but WTF.

Spoken like somebody who has no idea how politics works.

[Metro-One]

I really hope that this project is more than just the tunnel.

The highway and interchanges need a rebuild, especially if we want to have a true rapid bus / transit system.

While I still prefer the bridge over the tunnel and feel much of this has been a stunt, if the NDP can follow through with the above they may have actually swayed my vote (also largely because up to now they have done nearly no virtue signaling identity politics crap)

[connect2source]

Nice summary and I'm in full agreement. Perhaps a glimmer of hope that the bridge option will be revisited.

Although a great opinion piece, the bridge option is over. Millions already wasted with preloading and site preparation, then study after study thereafter. What we are left with is an 8 lane submerged tunnel that will not be finished until at least 2026 given the difficult construction window and environmental encroachment into surrounding areas.

Preloading is not a waste and will be considered money in the bank for future road improvements. Its not like the sand will go bad. Event he test pile that was installed has value as it gives geotech engineers much data on the ground conditions for future works.

Lol, that was an opinion piece written by one of our very own!

Unfortunately, the bridge is dead unless the Libs win the next provincial election.

[ssiguy]

What people who support the 10 lane bridge happen to forget, much to the benefit of the Liberals, is that the bridge was to be tolled. Of course the Liberals never mentioned how much but in today's dollars it would probably come out at around $5 each way. That's a lot of money out of people's pockets. The twinning of the tunnels however, as I understand it, will be toll free.

I thiunk the ideal setup would be 2 lanes in each way connecting Vancouver and Seattle traffic and the other 2 lanes each way be for strictly traffic from Steveston to the SFPR.

[LeftCoaster]

Either way it costs money...

Whether tolls or taxes pay for the bridge it's money out of the pockets of British Columbians.

The tunnel isn't just going to build itself out of unicorn farts.

[officedweller]

The other thing that people forget, however, is that the tolls on Port Mann (and Massey Bridge) are part of an overall scheme
of Traffic Demand Management to extend the period of free flow traffic for the structure before it reaches capacity.
You can already see the increase in usage at Port Mann with the removal of the tolls.
That means it will become congested/overburdened well before it was planned to be.
