Have you every walk, bike or driven on that section to see what the issues stopping the line to be extended?? Its a very narrow road with parking on it. Any transit line will have to be in mix traffic with on street parking remove.From link.
What about the 505 Dundas streetcar? Couldn't the TTC extend the 505 east from Broadview Avenue over to Carlaw Avenue, then north on Carlaw to loop at Gerrard Street East and Old Gerrard Street?
From link. Gerrard Street used to be a jog at Carlaw Avenue to get around the railway. The TTC could reuse the old street as a right-of-way to loop the 505 streetcar to serve Gerrard Station.
As for Roncesvalles stops, there was a huge fight doing what there and one reason some stops are there that shouldn't be there. Seen very little confit between riders waiting for a streetcar and cycles. Seen a few cycles not willing to stop to allow riders on or of the cars.
There was a plan floating around and not sure who it was for that cars would be able to drive over a similar style platform like a cycles. I would oppose it as it open the door to a lot of issues with riders seeing the same thing like today were cars bomb pass flashing open doors with worse results.
Transit priority traffic signals is a no no in Toronto and how does a streetcar use one when there is a car in front of it??
