Is their a study supposed to be happening on HFR?
There's a number of them already completed.
When do we expect results from that and is there really a chance in hell that it happens?
It would take an FOI request to see them. I'm led to believe two are not supportive of a business case by VIA's terms, one is, but they were based on faulty assumptions.
Is there a chance this really happens? Yes, an excellent one, but only a very slight chance that it's within VIA's domain save for being the prime tenant. If Private Finance has the pockets to invest in this scheme, they'll do it 'right', and that's HFR+, and inevitably with off-the-shelf tried and trued EMUs going faster than the present via stock or Corridor Replacements.
The Class 7 track and 125mph is a bit of an anomaly in Canada, as max speed, let alone common sense, is dictated by grade separation. If it is catenary (inevitably) then at grade crossings are an invitation to disaster, let alone from collision. This also means that top speed will approach that of HSR, But there's another distinction, as the cost of going full HSR as opposed to HFR+ pushes up the cost geometrically for very little gain.
This won't be a case of Private Investment being brought into the Infrastructure (or other) Bank. It will be a case of the IB along with VIA being taken into a P3. And the Ontario and Quebec Gov'ts also might. This will make an excellent commuter route as well as premium express freight. As prime tenant, VIA gets to choose pathings and slots along with the consortium's own Express EMUs, either under the VIA flag, or their own. Electric locos might also be available from the Consortium to take Corridor Fleet diesel hauled consists along the electrified length, like locomotive tugs do on the Panama Canal, for instance.
The money is certainly there to do this and vastly more. Just not government money. The reason the Feds will have a share of this is to allow the Consortium preferential treatment under present and future Law.
The demand is there, It will get built.
