Well, I'm trying be pragmatic and realistic about this. SELRT in all likelihood cannot be stopped. It, along with SRT revamp and TYSSE are Pan Am Games priority lines which it make it an uphill battle to convince TPTB to cancel or even alter these projects in any significant way. SELRT will be completed by 2013, so that gives us less than 3 years to find an influential politican that's pro-subway and who can convince the Prov./Feds to defer payments from SELRT to commence subway expansion. Considering the way the TTC operates, that $950 million would get us a subway no further east than Warden Avenue. Meanwhile service east of that point would get no improvements. I don't count on the TTC building dedicated bus lanes if I'm gauging the hostility towards BRT correctly based on my experiences here. So baring all that in mind, I'm willing to sacrifice the Sheppard corridor for now. It's a billion dollar mistake which I think will cost Toronto for generations to come, but I'd rather focus my energies now on saving Eglinton crosstown from the same ruination. Hopefully the TTC reconsiders its terminus design at Don Mills to make the LRT platform vis a vis with the subway's to at least minimize the affects of transferring. I'd also hope long-term that if the LRT is there to stay that they'll consider an interline branch that runs down the Uxbridge Sub to link up with the SRT guideway into SCC. That way at least some semblance of the NYCC-SCC higher-order transit link is retained.
But without Sheppard in the picture, this places extra emphasis on extending B-D to Scarborough Centre. 2 lines aren't needed here immediately but one more than certainly can be added. And the intermediates would be very well used considering half the routes that feed into Kennedy Stn today could terminate at Brimley. To build a 2 storey platform area, including a set for the future Eglinton subway connection sets the stage for ongoing subway expansion. Montreal itself has done this, both at the Lionel-Groulx interchange stn and at Snowdon which by the mere existence of the infrastructure makes it easier for STM to one day extend the Blue Line into Montreal West. Likewise in the west end, building the first phase of Eglinton subway gives us the opportunity to build a complex interchange stn at Mount Dennis while it's still relatively affordable to do so; which can lead to fasttracking the DRL to be completed within the next 25 years.
