What can be done with Scarborough Subway, now that Ontario Line route is more or less set.
SRT corridor to Hydro corridor to Thorncliffe.
Here it would temporarily interline with the Ontario Line. The next phase of this Scarborough Line would forge it's own way downtown, through the valley, up Rosedale Valley, and down Jarvis.
Cost.
$0.2B for funicular from Lawrence East to Kennedy (1.5km connection to B-D).
$1.0B to rehab track from McCowan to Lawrence East (5km, 5 Stations).
$2.0B to elevate from Lawrence East to Thorncliffe (6 Stations, 8km).
$1.0B to lengthen all planned Ontario Line Stations to accommodate this additional demand.
Other phases
$0.8M Throncliffe to Sherbourne (6km ,1 station).
$1.5B to mostly elevate from McCowan to Malvern/Finch (4 Stations, 6km).
$6B? Down Jarvis, across King, and up Roncy? (haven't really thought about this route enough - maybe 12km up to ~St. Clair).
