Service can only run so often through a intersection, once service frequencies drop below a certain point then half of the trains will have to be short turned at Laird even though a large number of riders will be going to Don Mills. If the line is separated through to Don Mills then presumably there will be no need to build storage and crossover tracks at Laird, this would likely save a significant amount of money and disruption as those tracks more than double the length of the underground structure required.
The seems to be a much larger about of left turning traffic at Leslie and Eglinton than at most major intersections as it is T shaped. As I recall, currently at Leslie and Eglinton there are dual left turn lanes for the south and east bound directions; and eastbound through and southbound left turning movements can be made at the same time. The planned layout for this intersection will remove one of the eastbound left turn lanes and no longer allow for southbound left turns to be made at the same time as eastbound through traffic. So the planned design would have a greater effect on traffic at this intersection than at most, so I would say it is worth the effort to change the design.
Good points...I'm convinced!
