I mean we'll just have to wait and see how things work out when the line and its extensions open, but I don't think the line will have to be split. There are many lrt lines that are just as if not more prone to delays that are longer and manage. I think having everything ready to split the line in two at science centre will be good for if there are any delays on either side, but having the line split in two during normal operation kind of ignores the point of having a "crosstown" line in the first place.Science Center is a far more important transfer point because of the Ontario Line connection. Forcing all trains to short turn earlier because of a single at grade crossing is just sad.
Sure, but any form of delay will have serious knock on effects. Remember we're considering Eglinton here including the Eglinton East extension, so now if you want to transfer to the Ontario Line northbound, or even trying to reach Scarborough Center, you know have to get off your train, wait for another train to pass, and them maybe you can now continue east just to ride it out 2 stops, all because of some accident at UTSC. The thing about YUS is that while delays do happen due to its length, at least its fully grade separated so the causes of delays are limited to some guy decided to run on the tracks, or someone held the door. With Eglinton, trains in Etobicoke can be delayed due to anything from some passenger taking too long to cross, to a car resting on the tracks because of congestion, a car accident, poorly timed traffic signals, or some idiot walking along the tracks (far easier and far more likely compared to the subway).
