Different projects have different needs. Spadina didn't need a new yard (well, the TTC Wilson yard expansion was budgeted as a different project), Eglinton needs a yard. Spadina ties right into Downsview station, Eglinton needs to entirely rebuild every interchange station. Eglinton station's subway platform will be completely rebuilt 70m to the north. Kennedy is getting a complete facelift and reconstruction. Spadina is constructing subway stations in large, undeveloped plots (other than Finch West, which is in the street), Eglinton is building stations in dense urban environments. The differences are large.
Eglinton when entirely buried in the Ford era would have cost $8 billion for the whole thing. Surfacing the eastern 8km gives you $3 billion in savings. The Broadway line is for Skytrain, which is much cheaper to construct than LRT for underground. TTC had a very negative experience with Skytrain tech too, remember that.
station spacing on the surface portion of the line averages over 650m, not sure where everyone is getting 300m from. The shortest station distance is 300 metres, sure, but there a part that is 1.2km from station to station.
station spacing starting at Laird and going to Kennedy is as follows:
1250m
930m
420m
660m
960m
860m
430m
470m
300m
770m
530m
640m
Hardly 300m station spacing, there is only one stretch under 300m, and most are above 600m.
"never considered elevating it", well part of the line
that is actually getting built is elevated. So I don't know what you are going on about.
If you want to compare completely different projects like the Evergreen line, lets do that within vancouver as well. Why the heck is Broadway so expensive? 5km of rapid transit for $2 billion? Vancouver is building 11km for $1.4 billion right now!!!!! Different situtations require different solutions. Period.
This whole subject has been rehashed probably 100 times at this point in this thread, I'm getting sick of it. Every couple of months someone pops in and says "but no grade separations and 300m stop spacing!!1!!1!" Cool story, too bad its exactly that, a story, not a fact, and it is ignorant of the planning context that the line has been planned and is being constructed in.
Different contexts require different
