As I understand it, the only real difference between a Transit City line and the St. Clair right of way as-built, is the stop spacing. I might be wrong, but I always assumed that the station infrastructure for a TC line would be very low tech: a longer, wider shelter, unmanned and without any fare control, and where access to the street or the other platform is done at the surface on a crosswalk.
Really, I can't see it any other way, with the TTC's absolute insistence that Transit City right of ways must be placed in the middle of the road (including the idiotic Eglinton alignment through Etobicoke where the Richview corridor is a huge strip of grass).
TC and ST Clair will be the same, except TC will see wider platforms as well longer ones since they will hold more than one car. I don't expect to see centre poles for TC.
There are places been look at where TC will be on one side of the route in places like Cherry St.
The biggest issues facing TC is the short distance between blocks as well driveways. This force the ROW to the centre of the road.
The Richview can support one side of the the road for the ROW, but some changes will have to made to make it work.
Any new LRT will work on St Clair and St Clair was to be the showcase for the new system, but the city kill that vision, not TTC.
Stop spacing is an issue regardless if it TC or St Clair. There are stops on St Clair that should not be there now.
As much as ppl want fast service along the lines if they are getting on near the end of the line, you got to think about the ppl who live in the middle as how far they would have to walk to a stop to please the fast trip riders.
400-450m is the max distance using the box or triangle to determined the walking distance on either side of the ROW to a stop. The distance in a straight line between stop would mean a rider has no more than 200-225m to a stop if they live in the middle.
Based on some stops I know that are being remove under TC, the walking distance will become 900m vs. the current 300m. Goes against the 5 minute walking distance to a stop.
