As much as I like Option 4 (and I think most people here prefer that one as well), I think there is going to be lots of pressure to go with a cheaper version of option 3 and use the money saved to push LRT further east and west.
By a cheaper version of option 3, I mean the idea David Jeanes brought up on Tuesday, about extending the current O-Train to Bowesvile (which would be simpler than building a Transitway from Greenboro to Bowesville).
The questions I have about this option are:
1)Jeanes & Co are suggesting additional passing tracks be added to bump the service frequency up to every 7.5 minutes between Bayview and Greenboro... how feasible is this? Will service reliability be affected? With trains every 7.5 minutes, does the level crossing of the VIA line start to become a problem?
2)The OC website says the O-Train has a capacity of 285. If service from Bowesville was every 15 minutes, this means hourly capacity is 1,140 per direction. If it was every 7.5 minutes from Bowesville, capacity is 2,280 per direction. Is this sufficient for the 2031 demand? If we went with an option like this, are we going to screw ourselves at some point in the future when it reaches capacity and can't scale upward?
(Based on this diagram:

3)With the O-Train stopping at Bowesville and Bayview, someone coming in from Riverside South needs to transfer twice before they reach downtown (once at Bowesville, once at Bayview). Someone from my table suggested bringing the Talents down Sparks to the corner of Sparks & Bank- to me, the Talent trains seem to big to do this; does anyone have an opinion on the feasibility of this? This would be in addition to the tunnel.
I'm just trying to think of some other options- some in the east and west would send nothing to the south, but there is a lot of traffic coming from the south that needs to be accomodated, and we need to grow south instead of pushing ever farther east and west.
