Updated January 24: A video showing the proposed new layout of the eastern GO Concourse is available on the City of Toronto’s Union Station site.
The virtual tour starts looking down into the moat from Front Street at the east end of the bridge linking the sidewalk to the station building. Note that the moat is at a lower level than today and provides a direct path with no stairs between the subway mezzanine and the new lower level of Union Station. Although the moat is shown with no cover in this video, there will be a transparent cover over this area to protect from weather and to prevent water and snow buildup in the crossing. Also, the number of entrances through the north wall of the station will be greater than today to handle the large pedestrian volumes between the subway and the railway station.
The tour “flies in” through the north doors to the new concourse level. This is in the same space as the existing GO concourse, but at a lower elevation giving a very high space for this entrance area. The point of view pans west toward the centre block of the building. Although it is not immediately obvious, there will be a stair up to the concourse under the great hall. There is already a change in elevation at this location, but it will be greater because the east concourse will now be lower. There will also be a connection into the Via Arrivals level.
The tour pans back and looks toward the east wall where you can see a stairway up to the east teamway. This is roughly where the exit to the teamway south of Front is located today.
Next, the tour flies south to the escalators up to the new GO concourse level. In the video, all six of the escalators are running “up”, but in practice this would be adjusted depending on flow conditions. At this point you can see the diagonal undersides of some of the connections up to track level. This design gives more open space than a simple box with a stairway inside it.
After we fly up the escalators, the view shifts to look back to the north and eventually comes back to the north end of the concourse. The layout, with the escalators a considerable distance south of the subway connection, is designed to spread out the pedestrian flows. In the original design, this connection was further north and the pedestrian modelling revealed that there would be congestion problems. My shifting the escalator south, GO passengers enter the concourse in roughly the middle of the space rather than at one end, and travellers waiting for trains on this level don’t block people trying to continue further south. Schedule and departure information screens are provided throughout the concourse to avoid congestion problems with many people clustering around few screens.
Finally, the tour looks down into the lower concourse from north to south, toward the bank of escalators.
