This proposal would eliminate the RH-GO line altogether, and replace it with just a single subway/metro rapid transit line.I used to be into something kinda like this, but I don't think it really works. Even decades ago it was deduced that any RL line should be a subway/metro class system, i.e one separated from both road and mainline rail. We can't exactly mix the two, and I doubt there's enough space to put a 2-track subway guideway while leaving space for the mainline.
RH line should definitely be improved upon/extended, but the same goes for all GO corridors. Not to mention the building of new corridors (something we haven't seen since the early 70s probably). I think there's definitely room for outside-the-box thinking, using surface corridors, different types of rolling stock, open-air infrastructure etc with the RL... But it seems pretty cut and dry at this point that the line must be subway/metro.
My understanding is that RH-GO corridor is not shared with freight? It is fully owned by Metrolinx south of the Doncaster Diamond.
(*also I have to correct my earlier posts, I forgot that RH-GO passes Don Mils north of Lawrence, rather than north of Eglinton)
