VIA Rail

Talking about the Electrification of St. Jerome Commuter Line and VIA HFR new tunnel options - This alignment offers significant improvements to St. Jerome, Mascouche, Candiac and Vaudreuil/Hudson Lines by allowing ALL commuter trains direct access to Gare Centrale, while allowing VIA an even better route to Laval/Quebec City, than the Mount Royal Tunnel would have provided....

You may want to look up Avenue Atwater and Rue du Fort on Google StreetView, as both will be in the way when attempting to dive underground anywhere near where your map indicates the tunnel portal. Similarly, vertical access at Gare Centrale would be a massive problem, as the existing tracks are in the way (i.e. between station concourse and your underground station). And speaking of the underground, have a look at a map of the "Underground City" and the Autoroute Ville-Marie to see all the stuff which has already been dug into the ground:

 
Yes - very costly (but quite beneficial!) I was thinking for the tunnel to dive down after Atwater and basically follow the path of the proposed PInk Line - Not sure how much technical work they did on that? The Pink Line presumably had a station under Gare Centrale. But its somewhere to start.

I'm afraid you will need to show at least some inclination to consider all three dimensions, if you want me to take your lines on a map serious...

^The only way I could see doing this at a price VIA and Exo could afford would be to build off the throat at the north end of Central station…. Or perhaps share with rem as far as the new rem station at McGill and branch off there. A short shared operation might be more doable than sharing for the full length of the existing tunnel. But even that is very fanciful as there is likely lots of stuff in the way, and construction at McGill is well along.
I do think you have picked a good location for the tunnel to join the Quebec/Ste Therese line. It’s that first 750 metres from Central that’s the killer.
One senses that Montreal may consider some Exo lines as expendable once Rem and maybe the pink line are built.

Would like to know how much research went into the Pink Line route... As the Southern part of my route would essentially mimick that alignment. (including the portal) The Pink Line was expected to surface around the area of my portal and travel at grade in the corridor until Montreal Ouest ...and there would be space for a station under everything else. Pink lines route is not too close to the Ville-Marie, and it passes under the REM.

There is neither the space, nor the money nor the stomach in Montreal to digest the construction of two underground rail corridors across the city. And I couldn't blame my fellow Montrealers if they chose a Metro line over an intercity tunnel which would only benefit passengers travelling between Montreal and Quebec...

Yes I agree that there wouldn't be the stomach for two new rail tunnels. But to be fair, the intercity tunnel wouldn't just be for the benefit of people travelling from Québec. It would also serve all of the northern and eastern suburbs via the St Jérôme line, and Mascouche Line, respectively, as well as the VIA long-distance services from Jonquière and Senneterre (and more importantly, Shawinigan and Joliette). And as drawn, it would also serve the western lines (Vaudreuil-Dorion and Candiac), providing them with a new connection to the various services using Gare Centrale (REM, VIA, Amtrak and other Exo Lines).

If the tunnel were to be funded by the City of Montréal, then certainly they would choose a metro over an intercity line. But large infrastructure projects like either of those are typically funded mostly by the province and feds, so the fact that the benefits are spread across the province is actually a point in favour of a mainline rail tunnel.

Well I don't think this dotted line on a map was intended to be a design submitted for construction. It's clearly just a theoretical concept.

Which is how planning works. First you start with a concept, then you dig deeper to see if it is feasible, and if so, how it compares to other alternatives (including Do Nothing). The more interesting reponse would be to provide examples of obstacles which would make the new tunnel infeasible.

My point was that only a much smaller proportion of Montrealers (i.e. those people who would have to suffer most of the disruption caused by the construction) would benefit from the operation of a heavy rail tunnel than of an additional subway line...

[rant]Which is exactly what I did (even with a link to an older post of mine in this very thread, where I already discussed most of these concerns in great detail), but this commenter chose to hand-wave away all the concerns I mentioned (e.g. Avenue Atwater and the Rue du Fort tunnel are too close to each other and too steep to dive underground inbetween, an underground station underneath the existing tracks would be inaccessible from the existing station concourse and in the way of the various arms of the Autoroute Ville-Marie tunnel and the underground city prevents you from being anywhere close to the street surface), rather than considering the possibility that someone who has actually lived in this city for 9 years, worked for VIA for 6 years, lived within walking distance of Avenue Atwater and the Rue du Fort tunnel for 2 years, been involved in the negotiations with the CDPQi and read more HSR/Higher-Speed Rail studies than most of you have heard of might have a more profound understanding of the engineering challenges of ploughing a railway tunnel through this city than a Crayonista who arbitrarily draws lines over a map...[/rant]

Honestly I dont expect anything but the current routing the Mascouche Line takes out of Gare Central becoming permanent and HFR simply following the same route.

The entire purpose of the Côte-de-Liesse REM station is to provide a transfer to the Mascouche line. The station is located on a spur relative to the CN line, so in practice trains serving it will need to terminate there. I don't think we know yet whether VIA will terminate its Jonquière and Senneterre services at Côte-de-Liesse or bypass it using the current huge detour route to Gare Centrale.
