@Urban Sky
I appreciate your analysis that this would be an undertaking that's a large step forward. The thing is, I'm not sure how VIA is really sustainable without that step forward. VIA's average speed have dropped over the years. And it's getting worse with more freight congestion. If VIA is to actually contribute to effective relief of the 401 (which might need triple lanes in both directions going forward), we'll need proper rail service in the corridor. And to do that, you're going to be building an exclusive right of way anyway. And again, if you're doing that, the cost of going to full HSR is rather incremental.[...]
This could be what happens to VIA HFR incrementally if HFR is a big success -- high speed trains gets introduced later as we add grade separations & track upgrades that speeds up sections.
So 20% true HSR and 80% HFR, we might be running high speed trainsets mostly on non-HSR routes initially just like these routes. Speeding up the train as true HSR track upgrades are added in additional legs.
The main challenges faced by VIA Rail is a continuously deteriorating travel time and on-time performance, which together with its inability to increase the frequency of its trains translates into a declining ridership (and a cost-recovery rate on the Corridor which has fallen to 60%, as operating costs are proportional to travel times) and the main objective is to tackle these challenges as soon as possible and to get independent from federal subsidies in the medium term. Given the federal government's lack of appetite for large-scale passenger rail infrastructure spending, the solution has to be as financeable (i.e. affordable) and cost-effective as possible. This is why a design speed of 110 mph was chosen (i.e. the maximum allowable speed which does not require grade separations) and the need for greenfield alignments was almost entirely avoided by choosing former or currently underused ROWs. Naturally, this means that the new dedicated infrastructure will be of limited use for eventual upgrades to HSR, but HSR does not play any role in VIA's planning horizons anyway and VIA won't make it HSR-ready unless the federal government (or its private investors) agree to pay for the associated cost premium. Furthermore, an incremental introduction of HSR would require the trainsets to be Hybrid, as it is extremely unlikely that CN will ever allow electrification of its Kingston subdivision, and be subject to the same capacity constraints and frequency limitations VIA faces currently.
[...] HFR seems like an attractive alternative at first blush. But the more I look at it, the more skeptical I become. The Peterborough route they are proposing would be politically untenable since it would really harm service for all the smaller communities along the corridor. Also, we can't be sure they'd have lots of traffic by cutting out all those smaller communities. It's riskier to base such massive investment solely on tying Toronto, Ottawa and Montreal. But if the alternative is then going to be following the Lakeshore, why would we not build HSR? Don't even have to electrify at first. First build the corridor and run semi-high speed diesel services. Perhaps run out the current rolling stock. Electrify down the road (when GO RER is up and running).
VIA's current Corridor trains between Montreal, Ottawa and Toronto are basically hybrid trains which try to serve two different markets, i.e. the MTRL-DORV-(OTTW-FALL)-OSHA-TRTO
express inter-city market and the
regional inter-city market for all the cities in between, which unfortunately have conflicting demands (short travel times for Express and frequent stops for Regional). HFR will therefore allow to serve both markets more effectively, by having frequent and fast
Express trains and less frequent, but more frequently stopping
Regional trains on the Kingston subdivision. As with "making it HSR-ready", VIA is open to build HFR electrified from the beginning, provided that its investors agree to pay the cost premium.
[...] I agree that political will is lacking. In no small measure, because we get hooked on the price tag, rather than the reality of incremental development. HSR in the Corridor for example would be built in parts over 20 years. Toronto-Ottawa-Montreal by 2030. Montreal-Quebec City and Toronto-London by 2035. London-Windsor by 2040. With inflation that's a max of $40 billion spread over 24 years. $1.7 billion per year. It's doable. But it requires a firm commitment, on a multi-decade undertaking that should hopefully survive successive governments. [...]
Okay, let's look at how your plan for HSR on the Canadian Corridor compares with the leading HSR nations. I have retained Japan (as the first HSR nation), France (as the first and leading European HSR nation), Germany (as the leading hybrid HSR nation where High-Speed trains and Higher-Speed inter-city trains use a mix of dedicated and shared tracks) and Spain (as the world's densest HSR network), while removing Italy (too similar to France) and China (too dissimilar with Canada's political, demographical and geographical reality). As you can see below, your plans appear to be well in line with 3 out of the 4 countries:
Note: The x-axis should rather say "Years passed since government approval of the construction of the first HSR line segment"
However and as I have already mentioned further up in this post, I still insist that comparing the HSR network lengths is a valid measure for the
evolution of HSR networks, though not for the
final network length itself. Relative to the respective population figures, you plan on having completed MTRL-OTTW-TRTO 2 years earlier than even Spain has managed to reach such a density (15 mm/capita) and that is assuming that the go-ahead comes this year. Furthermore, you are planning to complete QBEC-MTRL-OTTW-TRTO-LNDN during a period in which only Spain had reached such a density (25 mm/capita) and France had only reached half of that. The same can be said about the period in which you want to have completed the entire Quebec-Windsor Corridor (29 mm/capita), with Japan being this time the HSR nation which had only reached half that figure (and let's not talk about Germany):
@MisterF is correct.
I was surprised when I found out how close the densities were.
Southern Ontario: 86/km2
Spain: 92/km2
France: 116/km2
And I'll be if you re-adjust for the high population of Paris, the rest of France looks even more like Southern Ontario. Germany is an anomaly. Even in Europe. [...]
I'm afraid that
Spain and France are the anomalies, while among the 11 European countries with dedicated HSR infrastructure, only Switzerland and Italy are closer to the average density of these 11 countries than Germany:
