It would be fun to take WislaHD's base map and use it to create a full catalogue of the semi-disjointed PATH networks in the core. (Not just Yonge/Bloor, but the ones hanging off Bay, too.)
Do I read Wikipedia correctly that the PATH is only 3 km shy of overtaking Montreal's RESO as the largest underground city in the world? http://en.wikipedia.org/wiki/Underground_city#Canada
I have actually been filling in future sites and extensions of the PATH network gradually over the past few days. I haven't done any 'hanging' off of Bay though, do you mean at Bay station?
And yes, the PATH is pretty unique even globally, I am pretty sure it is already the largest shopping complex in the world. If we keep fostering its growth, I am confident it can become a uniquely Torontonian landmark and tourist attraction. We can even utilize it to overcome some of our biggest problems, like the physical barrier between our lakefront and our downtown created by the Gardiner, Lakeshore and the rail corridor.
One small suggestion for WislaHD's map: the BD subway should be green instead of yellow. You also might want to consider adding the Yonge station platform on the BD line, although there are no direct PATH tunnels connecting to that platform.
I have been doing some minor adjustments here and there. I've added the future extensions of Harbour and Church streets, fixed up the Bloor-Yonge subway intersection a bit, and yes added the Yonge platform at B-Y. I will look at coloring line 2 green. Speaking of which, does anyone have an accurate map of the locations of the subway platforms and tunnels? I was mostly guesstimating when I was doing it.
