True but the current SRT has quite a bit more capacity than this thing, and that's with the vehicle shortage. So, you're talking about something with similar capacity as a 2 lane BRT.
If you built it with capacity matching Eglinton, the stations would need to be quite a bit larger. Chicago loop stations are smaller than what would be required today without code changes, so imagine something over the street larger than that. I'm going to be a NIMBY due to stations.
Also curious as to how our firecode would deal with a large vehicle that doesn't have any emergency exit capability. Inflatable slides?
The Pearson Airport train gets away with it due to the low capacity. A single ladder truck could unload it in an hour. A stuck train with 900 people on board would result in a 4 alarm call just for the equipment to unload everybody. I've been trapped in gondola's on more than one occasion for more than a few hours while they roped people down -- not an easy thing to do when everybody on board is physically fit. A typical Eglinton train during rushhour in 2020 will have ~200 people who have severe difficulty with stairs (assumption of boomers still taking the train into their 60's and obesity continuing to worsen).
