Its a bunch of huge high speed elevators with large volume throughput.
Its an engineering solution to a problem, something we are unfamiliar with here in Toronto.
Toronto = "we paid a consultant firm with very specific outlines of what we wanted the results of the report to come up with, and not allow for any innovative ideas, because we favor a specific outcome over coming up with solution"
That end result is usually a half assed approach (ie no grade separations here, or a pedestrian walkway for the Waterfront LRT) or to abandon the project entirely.
The results are usually based upon "beautification" ideologies, for example with the ones I listed, "oooo at grade LRTs are so pretty" or "a walkway is so chic and European"
Just look at how the renderings for this favour the look and feel of the at grade LRT option, or how they played up the walkway for the Waterfront LRT as some kind of art installation thingy

Meanwhile Mississauga gets a fully grade separated transitway, and York region a tunnelled subway with behemoth stations.
