Let me suggest, on the subject above,
@Reecemartin's issue w/the tight curvature.......
He's not wrong..........
But may be overlooking secondary motivations for the alignment.
I would suggest that development opportunity may be a consideration. Its easy to see why. Though, I would argue, that would still be ill considered even if that motivation were primary.
I think a faster line that hits key marks, near redevelopable lands could be found to the west and be at least as interesting if not more so.
To be clear, I don't expect the choice here to be revisited, for better or worse. But I'll throw this out anways:
View attachment 706808
Justification:
Shorter distance
Gentler curve.
Leaves existing Oshawa GO/VIA station where it is.
Allows for a Station at Simcoe, close to downtown.
Concentrates new development opportunity next to GO Station and Simcoe which is also likely a future higher-order transit corridor.
The routing is slightly sub optimal, but I was seeking to minimize adverse impact o the valley lands.
