Pipelines, energy and natural resources

I will certainly accept your knowledge on that but before anyone buys in they have to know that the barrier will be circumvented.

Kinda like how the government straight up said in the MOU and pipeline plan they would use the exemption system?

However, Eby said in a statement issued Friday that it can’t be the case that projects get prioritized in Canada because a premier threatens to leave the country, referring to the separation movement in Alberta.

A province threatening to leave the country, prompting the country to make offerings? Certainly this has never happened in Canada before.

This will be a tricky question to address, not a lot of room or options to replace it

so now they have to actually state to what extent they are going to do just that. I will buy that but not a sometime in the future promise to do something. I have bought too many used cars on those types of promises to believe them

You tunnel it.
Rail tunnel between Windsor - Detroit is over 100yrs old

Rail tunnel between Sarnia - Port Huron - the first one last over 100yrs. They replaced it with a new one about 25+yrs ago.

Not sure Vancouver is seismically sound for a rail tunnel? I’m not sarcastically suggesting it isn’t; I genuinely have no idea. I just understand the potential for earthquakes to be a bigger deal out there than here… I
could be completely wrong in that mattering.

if you are looking for historical tunnels how about Brockville?

The bluffs on the south end into which the existing tunnel runs are solid rock. The causeway on the north end might not be as solid.

Twinning might be an easy option for the crossing, with the south end quickly joining the existing tunnel.

If a substantial earthquake strikes, there are going to be much bigger problems than that particular chunk of rail, even just among all the rail in the area.

And it's really cool what they've done with it.

No engineer but in order to tunnel the narrows they would have to tunnel under the existing Thornton Tunnel then do a lot of re-arranging on the north shore to enable a suitable grade. It gets very busy with industrial trackage very quickly after the bridge hits land. I would think a new bridge or twinning would be much less disruptive.

This strikes me as CN (and probably CPKC as well) not keeping up on its state-of-good-repair. They had another mainline bridge failure on northwestern Ontario last year or the year before.
