Are 3 min frequencies even physically possible?
Are 3 min frequencies even physically possible?
Yes with a significant investment and more than a bit of land expropriation to continue to allow longer-distance GO service. A pair of tracks dedicated to the service with zero interference from any other GO services would be required.
For a North American example see the tunnels under Hudson River from Penn station to New Jersey. They've been handing 24 trains per track during the peak AM hour for over a decade.
You are getting into the same ballpark as a relief ine, definitely.
That is why SmartTrack needs to be converted into a Toronto-specific fare zone with more Toronto stations along the GO-RER corridors.That's why Smarttrack is redundant. If every GO line runs at 15 minute frequencies, they would combine to have frequencies anywhere from 3.75 to 7.5 minutes in the central part of the city. Obviously that's an oversimplification, but you get the idea. I still think that Smarttrack will get rolled into the RER system and not be a separate layer. At most it will result in a few more stations and accelerated fare integration. Which of course would be a good thing.

"Toronto downtown relief line still a fantasy"
Indeed.

Quite possibly. Your list does not include any expertise relevant to the core of transit building - ie urban planners, transportation engineers, civil engineers, railroaders, transit operators, etc. That's ST's huge flaw IMHO, great on sizzle but wouldn't know a good steak if he chewed on it. Ultimately, ST is still a napkin proposal. Every new Tory pronouncement underlines this. Hopefully the staff studies arrive soon to put some meat in the discussion.
Perhaps I should rephrase my question.
Anything is possible with enough money. But how much investment would be needed? There's never been a solid number put down, but I've seen estimates well beyond what a relief line would cost.
I wouldn't mind seeing in the long run, subways from RHC being interlined with a Relief Line LONG option north of Lawrence, to boost Relief Line frequency from 3.5 minutes down to 2.35 minutes (akin to Line 1) south of Lawrence.A route that I think is very much possible to see subway-like frequencies is the Richmond Hill line. And not as an upgrade to improved GO/RER, but rather a complete shift into the subway/metro category (i.e complete grade-separation, high platforms, automation, very high frequencies, etc). Considering its similarities to the DRL's route, I think this would work with the two morphed together as one line. Example: the City's Option A or D plan for the south end, Mlinx's Surface/Long for the central section, and a fully grade-separated RH corridor to RHC in the north end. This isn't so much an RER, but more like a subway that uses sections of the GO corridors - not unlike the GO-ALRT plan of yore.
