Transport Action Canada is an advocacy group and can propose/dream anything they want. CP might have something to say about it. |I don't know how much additional storage Metrolinx will need in the future - they seem to have a fair bit in the current Allendale yard and, if they needed more, finding property just east of Ferndale or down the Beeton spur would be closer. If nothing else, building a s/b - e/b connecting track at Utopia would require buying up a number of commercial properties. I'm also not sure how well the Canadian would weave into Metrolinx's planned service.
I'm quite confused. The old Allendale station is not on the alignment of the BCR; it's not huge, about 60m away but certainly not adjacent.
Metrolinx doesn't operate the Canadian, so I'm not sure why their rules would apply.
Who are you proposing using the Mactier sub? Metrolinx - they have their own route out of Barrie. Via - are you suggesting, between the two posts, that the Canadian come down the Mactier sub, go into Barrie, then back out to Utopia?
