Many of the GO train lines could share the same stations. If they had the proper signalling system.Is there room for 2 more tracks along that alignment, with it already carrying the Milton, Kitchener, Barrie, UP lines - not to mention VIA and possibly the proposed GO Bolton service?
Though I scratch my head about using 2 of the 6 possible tracks on Lakeshore East for a short distance with a line that could be tunnelled; as it's looking like Lakeshore East, Stouffville, and both the VIA HFR and Kingston services are going to to on there; possibly GO Peterborough as well.
Look at New Jersey, with all their trains going into Penn Station in New York City...
