I understand these concerns, but if we only focus on investments which are HSR-proof, then what can we actually build now to get the frequencies we need? Also, the question of "future-proofing" does not just work HFR vs. HSR, it also works Higher-Speed Rail vs. "full" HSR, as the F-200 scenario described in the Ecotrain study was assumed to be designed for a minimum radius of 2,500 meters (2,000 m with tilting trains), whereas the E-300 was to be designed for a minimum radius of 6,000 meters. As you might imagine, the resulting alignments differ significantly in certain areas (especially: Dorion - Casselman and Napanee - Port Hope)
Note: The F-200 alignment is shown in red, whereas the E-300 alignment is shown in blue and a more detailed map can be found in
Deliverable 9 (Appendix I) of the Ecotrain Study

Given that the infrastructure cost premium of E-300 over F-200 is only 18.6% for Quebec-Toronto ($14.04 billion vs. $11.84 billion in 2017 values, see Post
#5,002 for these and all other figures mentioned in this paragraph) or 21.6% for Quebec-Toronto ($9.41 billion vs. $7.73 billion), while reducing travel times between Montreal and Toronto for an additional 51 minutes (2:47 vs. 3:38 hours) or 23.4%, there seems indeed to be little reason to settle for a Higher-Speed Rail rather than a High-Speed Rail future. This is even more the case as two-thirds of the cost premium fall on electrification.
Okay, so let's identify the sections where investments will reduce travel times for the current services and remain "most compatible with an HSR future":
Note: ROW sections eventually shared with HSR are highlighted in green, whereas existing and new ROW sections which will not be eventually shared with HSR are shown in yellow and red, respectively.
Compiled with: distances obtained from
historic CN/CP timetables or measured with Google Earth and routings obtained from
The Globe And Mail (for HFR) and the
Ecotrain Study (Deliverable 5).
You can check yourself, but I can only identify 3 segments which meet both criteria:
- The Montreal Subdivision from Gare Centrale to Dorval Est (14 km, owned by CN)
- The Alexandria/Beachburg/Smith Falls Subdivisions from Casselman West to SmithsFalls North (104 km, owned by VIA)
- The Kingston Subdivision from Port Hope West to Toronto Union (94 km, of which: 60 km owned by CN and 34 km owned by Metrolinx)
Combined, these 3 sections account for only 212 km (or 33.5% of the total distance between Montreal, Ottawa and Toronto) and the CN-owned part of the Kingston Subdivision only accounts for 60 km. Even worse, these 60 km omit the nodes (Coteau, Brockville) which are presumably the choke-points of the Kingston Sub, while none of the triple-tracked sections falls into this part which will be hopefully used by HSR one day. I would therefore like to know from you and from
@crs1026 how you are planning to reach the frequencies required to justify HSR investments (by demonstrating that the Corridor is commercially viable for InterCity rail) without massively investing into infrastructure which will no longer require these enhancements once the HSR line we are all hoping for will finally open...
