There are multiple options within the LRT technology choice on Eglinton. One option (which Steve Munro would prefer) is to run a short-turn "tunnel" service in addition to the long-haul Crosstown service. Those short-turns would provide additional capacity in the most used central part, as well as schedule stability.
Another proposal, from Karl Junkin: in the surface parts, run part of service as "local" and another part as "express". At "local" stops, local trains would pull to side tracks while expresses would run on the two central tracks. Thus, four tracks will be needed at each stop, but only two everywhere else. In the tunnel, both services would share same stops.
But even if TTC prefers SRT-style operation, speedy and fully grade-separate, for the whole length of Eglinton, it makes sense to use LRT type vehicles / gauge / power, for compatibility with the rest of the system. Basically, build an "LRT+" line on Eglinton, that is fully grade-separate, and has speed and capacity similar to ICTS.
Such "LRT+" will cost more than the originally planned LRT, and probably no less than ICTS. But there will be advantages of larger vehicle orders, common maintenance facilities, common station at Pearson (with Finch LRT and possibly Mississauga routes). Light rail is coming to GTA big time, even if some lines are upgraded to subways.
@Rainforest, the thing about LRT's flexibility is that while Steve Munro touts LRT over ICTS for that reason the TTC's love of schedules over headways will always make them look at full segregation adoringly.
