Gaa. This seems to resurrect once or twice a year on here. If anyone can find a politician, local or otherwise, saying they are willing to spend gobs of both money and political capital to expropriate and tear up Barrie's essentially brand new and still infilling water front, I'd like to hear it. Similarly for somehow cutting a greenfield ROW around Barrie. A lot the land around Midhurst is zoned for redevelopment so, while not necessarily built-up yet, the land value is high. There is also a non-insignificant grade to deal with. It's no mountain railroading but it would either cause a circuitous route or a lot of cutting. And once they connect to CP, then what?
Sure, anything is possible with enough money and an iron will. Same with bulldozing a line to Wasaga Beach or the base of hills at Blue. Given the cost, for what benefit? Maybe there is a fantasy thread here somewhere.
