Yes, we need innovation in transit. We need LRT, transit priority signals, automated subways, and fare cards. Innovation means new solutions to problems. Whether you like it or not, we will keep on adopting innovations. Vancouver uses the same innovative technology as the SRT, and I think they're proud of their system, a fully grade separated rapid transit system that has as much trackage as ours for a city with at least a million fewer people, built in less than half the time as our rapid transit system.
LRT, signal priority, automation in metros, and fare cards are not innovations. It is tried and proven technology, is it not? LRT has been around over one hundred years, automation since the 60's. Innovation MAY mean a solution to a problem, but can also lead to costly fixes in future, the SRT being a perfect example. Skytrain works in Vancouver because Vancouver took on the project themselves, due to UTDC's incompetence. Vancouver is pretty much stuck with the technology now, and using the Canada Line as an example, are willing to move away from ICTS. Unfortunately, the premier has the final say in BC. and he wants to stick with ICTS, and seeing as Translink is having a funding problem, it's unlikely the next extensions of Skytrain will be built anytime soon.
The technology also has nothing to do with the speed of construction. It was politics that slowed the expansion of transit in Toronto, not technology. The Network 2011 plan, and the Transit City plan would have more than doubled Toronto's rapid transit network, and politcs got in the way.
Ground level power collection might never be that affordable, but if the kinks can be worked out, there are probably some prominent areas where it could be done with a high concentration of tourists, locals. I see as something worth considering at least on a limited basis for parts of the city where we'd like to show our best.
You do realize there are ways to make OCS look "invisible". The technology is already available to reduce the presence of OCS in an area. Toronto needs a quality transit system that works, not a system with a few "cool" toys. How many innovative ideas were presented that got nowhere in Toronto? Maglev in the 70's, ICTS, which used some ideas from the Maglev debacle, Cable-cars, Hydrogen Trains?
I do not see ground level power collection as a solution. New trams will be required, and specialized skills to maintain the system. Not to mention, only 2 companies are offering the tech, and neither are compatible with each other. Another problem with "innovative" products. You are stuck with one provider.
