Also the other question this whole document raises is where exactly are they putting the station at Kennedy?
Kennedy to Agincourt GO is 300m, meanwhile a full length subway platform is 150m. I really hope they don't just plop the station east of Kennedy, and require people to walk 150m to reach Agincourt.
A station at Agincourt meanwhile would allow for far better transfers, and I don't think diverting the Kennedy busses 300m east to reach it would be the end of the world. The only big issue I see is no direct subway connection to Agincourt Mall, but I think a direct connection to the Stouffville Line should be a higher priority.
In all options the station will be on the west side of Kennedy. A transfer from mode to mode is contemplated here. That can be seen on the maps.
The exact nature of the connection will depend on what grade we're looking at, but if, for argument's sake, the train were underground at this location, given that its depth would have to be sufficient not to disturb the rail corridor above, and that it would have go under the water table here as well, you can traverse quite a distance just going up escalators off the end of a platform.
For rough purposes, the escalator horizontal distance will be double the height it must traverse.
