This should make use of the existing tunneling equipment being used currently for Spadina, to build the tunnel between Finch and Steeles. So in the end it's just a tunnel, and then when funding becomes available they just have to build the stations?
That's a short way to tunnel for all the headache of trying to load a TBM in though. The launch and retrieval shafts alone would probably be like 1/3 of the distance between Finch and Steeles.
And I can see why they wouldn't want to build the station. No sense in relocating all of the 'terminus' infrastructure (large bus loops, etc) when the terminus would only be temporary. It's already at Finch, leave it there.
