Okay but what about other reasources? Potash?It won't happen, because the economics don't work. There is more than enough pipeline capacity now. This is just resource extraction populism which happens to sound visionary.

With the revenue coming in they could make improvements to the track, you can drill down to under the tundra to create a base using bedrock. You could refrigerate the tundra under the rails to keep it solid, there are tons of technologies that you can use. It just costs $$. Hopefully they can build passing sidings and increase the track speed.
In high-latitude tundra, permafrost – perennially frozen ground – lies a few inches to a few feet below the soil surface and can extend to depths of 2240 feet (683 meters).How deep would the bedrock be there?
You don't need to get down to bedrock, you need to get to a stable, well drained base. Part of the line, roughly from where it turns north near Gillam, is in the Hudson's Bay Lowlands, which is essentially a very large, flat, water-logged peat bog interspersed with outcroppings of silt, sand and gravel. It used to be a sea/lake bed. I tried to find some kind of reference for the general depth of the overburden but could not. If where you want to go allows you to follow on top of an esker, then you can have a decent, well-drained base; if not, you need to add fill, more fill and more fill until it stabilizes - for now. There is sand and gravel but you can't really quarry it because of the water table.How deep would the bedrock be there?
But retrofitting hundreds of thousands of pieces of freight rolling stock is another matter altogether, despite its advantages
It might be possible for certain types of trains. For example if you wanted to do it for double stack well cars or just coal cars or just tankers you could. The trains would need to be fixed to a specific type of car and matched with a locomotive with that coupler.The Digital Automatic Coupling (DAC) programme in the EU is seeking to replace the ubiquitous chain-and-buffers coupler on freight wagons with an automatic coupler that includes air and data. They're going to do this on half a million freight wagons and locomotives in Europe. I got a really good bit of insight from one of the project leaders when I was at the UIC symposium in December:
To most people, the DAC programme is an engineering challenge of testing and selecting the ideal autocoupler, ramming trains together, yanking them apart, etc. But to them, that's secondary. The primary objective of the DAC programme is sorting out how to deal with one fundamental issue: the railcar owners will be the first to incur the expense of retrofitting their fleet, but the last to receive the benefits.
Retrofitting ECP brakes on North American rolling stock would be a similar challenge, and I hope that the AAR(/TTCI) is watching and learning from our friends in Europe, because the European project seems to be moving quickly with very satisfied stakeholders.
I've been following the DAC progress - it's a massive project no doubt, and in some ways it is even more massive and pivotal than any project to standardize ECP braking in North America.The Digital Automatic Coupling (DAC) programme in the EU is seeking to replace the ubiquitous chain-and-buffers coupler on freight wagons with an automatic coupler that includes air and data.

Meh. Every time we ask for change the private sector peeps up and says how expensive it’s going to be. Every time we propose legislation and regulation the private sector cries about how they and the market are best-placed to decide.A second step might be to inject a certain amount of "inefficiency subsidization". eg, more captive fleets. paid for by government.

I say we demand an outcome and a timeline, and let the railways figure it out.
