Or, crazy thought. Instead of ripping up the 82 kilometers of existing track in a painful, expensive, piecemeal conversion process that will balkanize the streetcar network, we could build the not-yet-constructed, still-not-in-existence Jane/Finch/Eglinton LRTs in the same gauge as the rest of the city?
I think not using the same gauge as the TTC's network was Metrolinx's dumbest moves (and they've made a lot of dumb moves so that's saying a lot). The streetcar network is longer than all the LRTs they're currently constructing combined. The streetcar order is larger than the LRT orders. So why not have an Ontario gauge and make everything compatible?
I mean, if we were starting a network from scratch I would definitely use Standard gauge. But we have North America's largest legacy streetcar network. The purpose of a standard is so that everything is the same, but we already have a standard in Toronto (even if it may not be an ideal one).
Actually, TBH I don't care that much since I don't think a Jane LRT will go south of Eglinton since it would have to be buried because of how constrained the ROW is.
