Forget it - they (Paris RER) have a railway ring road planned.
In fact, Paris had one historically, much of it now used for RER:

And if VIA is cut back, would Ontario backstop some of that service with its own fleet and service contract?
The 'HSR' guise is peculiarly suited to do just that. Rather than the scenario you suggest, I think the re-alignment of the Windsor (Or more realistically, London) to Quebec City Corridor will become a provincial partnership, Ont/Que, with the Feds spinning the rest of VIA off into another org, and being a partner with Ont/Que, and Private Enterprise for the 'Eastern Corridor'. I don't see how the present status quo can remain much longer, VIA being starved to death at present, and the re-alignment of vehicle producers/operators.
France open to linking Bombardier with Siemens-Alstom merger
But:
Alstom, Siemens to merge rail businesses to counter China's CRRC
And:
Bombardier should consider rail deal with China's CRRC: Caisse CEO
Something's going to give, and it will be BBD, probably, if not inevitably, in pieces. European operations bought up by Alstom/Siemens, North Am ops bought up by CRRC (who have incredibly deep pockets to finance *entire* train operations, not just build rolling stock).
This thought gives a lot of excitement of the potentials of future orders (especially for rail- enthusiasts); the beginning of seeing Alstom and Siemens vehicles/consists in Ontario/Canada.
Yup, and I think we're seeing Metrolinx hedging bets on BBD. No more orders for equipment, just to continue running some services.
Let's be honest, its almost natural to expect that SNCF and Deutsch Bahn to have strong friendly partnerships with the two respective manufacturers.
Actually not. Procurement must meet EU regs, and it's very strictly enforced. And it's open to more than either Alstom or Siemens. None-the-less, consolidation is the name of the game right now, with some very good but smaller producers still in the game. Stadler is hitting way above its weight at this point in time. Even though Swiss, and technically not part of the EU, there's very tight EU trading agreements that render Swiss products *effectively* inside EU. (EEA and EFTA)
