A firm nod towards my
signature (as in: please note that I'm expressing nothing but my own interpretation of what synergies there might be lying between HFR and the Pickering Airport):
First off, I'm no fan at all of the aviation industry, as they are responsible for some of the most obscene destruction of our species' own livelihood (heavily taxed by the taxpayer to the point where people don't only choose the plane because it's the fastest mode, but also because its ticket prices make it often the cheaper than other, much more appropriate chances) and building additional infrastructure (just as with roads and cars) just encourages further, highly unsustainable growth. That said, I have to fly myself regularly to see my family and friends which live in my native Germany, even though I'm planning to limit myself to one return-flight per year in the future, following the
call of clima activist Greta Thunberg to boycott aviation.
That said, in order to reduce road traffic to and from the airports and the demand or the need for short-haul flights, there needs to be a strong integration of the airports within the transit and rail networks. Also, rail advocates are painfully aware of the highly detrimental effect of not anticipating future expansion needs when planning transportation (or other) infrastructure which often violates former ROWs. As you write yourself in the
article you've linked, you don't anticipate that Pickering Airport would be built before HFR (and god forbid that you will be proven wrong!), so this is more a question of making provisions for a future stop at the airport.
With this preamble, I would like to share the following brainstorming activity:

- Assuming that above map is still representative of your plans, I would believe that you can forget about the Y-shaped tracks into a rail station next to your planned airport terminal, at least where it concerns HFR trains, as this would add at least 10 minutes to their runtime, while a platform built and served along the Havelock Subdivision should at least halve that travel time penalty. You also seem to be unaware of how long your train station would have to be, especially if it was to host GO trains. Thankfully, all what a future station along the Havelock Subdivision would require at this point is to simply plan the HFR infrastructure with such a future station in mind, which only means placing signals or switches in a way so that they won't need to be moved later and should cause no non-negligible additional costs.
- For understandable reasons, you seem to believe that passengers will rather connect from downtown Toronto (i.e. GTHA-based passengers substituting the car to access Pickering Airport) than from Ottawa or Montreal (i.e. passengers substituting a connection flight), but the problem is that Transport Canada classifies VIA Rail as "intercity" rail, which prevents VIA from selling more tickets than there are seats on that particular departure. This means that whereas there will presumably be an abundance of seats available for downtown-to-airport travellers in the early morning or in the evenings, there might be a shortage at a time which might be the most critical for Pickering Airport: the afternoon peak around 5 pm, as any intercity rail operator who can sell every seat only once will rather sell it to someone paying $100* for Toronto-Ottawa than $10* for Toronto-Pickering. (*all these ticket prices are completely arbitrary and only provided for illustrative purposes)
- In order to solve the previous point, you would need to attract much more riders which are willing to travel between a Pickering Airport rail station and HFR destinations east of it, which will require an abundance of affordable parking spaces and a convenient integration into the regional road (and especially transit networks, with the first (affordable parking) being in short supply at almost every airport, while the third (transit integration) is a common weakness of the kind of secondary metropolitan airports like the one you are hoping to build. This would allow to sell the same seat for $10* to a Toronto-Pickering passenger and for $100* for a Pickering-Ottawa passenger. Otherwise, the afternoon peak downtown-to-airport connection could be offered by a future GO service (potentially extended to Peterborough), which would anyways be most likely to offer service during that time of the day.
- Unless you are on a Shinkansen line in Japan, any intercity service will offer frequencies which are inferior to that what downtown-to-airport rail links commonly offer (for which UPX with its 15 minute headways is a very typical example). The same frequency which your future passengers might consider as "frequent" for connecting towards Ottawa or Montreal, would be considered as "painfully infrequent" to connect towards downtown Toronto.
With all of that said (and despite my at-best luke-warm enthusiasm for Pickering Airport), I deeply appreciate your support for HFR and your determination to see HFR as an opportunity rather than threat for your vision!
You sounded so certain that I didn't even doubt your claim. It was only when I checked the report for explanations as to why the costs had been so sky-high that I re-checked the table...
Indeed, but your over-inflated cost figure made the whole HFR costing (wrongly) appear implausible...
You won't be surprised then that it was of course said deer friend
@steveintoronto, who provided two professional/academic articles about maintaining high frequencies on (partly) single-tracked infrastructure:
Given that the second paper is older than myself (and arguably the most relevant when discussing single-track meets), I've uploaded the Petersen et Taylor (1987) article
here.
In addition,
@steveintoronto also identified the following two impressive examples of high-frequency single-track operations (both of which I have witnessed myself):
It is posts like the above which make me highly regret his forced absence from this forum...
