First of all I never said anything about a bi-directional bus, although they are an option, but rather bi-articulated buses. These electric buses can now be up to 28 meters which is hardly much of a gap of the current 34 meter streetcars. Remember that much of the massive growth in the area will also be served by the Ontario Line and vastly increased GO service, assuming ML every gets around to offering it. Also, why does Union need a streetcar loop for this line when they can just run standard bi-direction trains. They already use them on Eglinton & Finch so what's the problem? As for the legality of bi-articulated buses, they can become legal with the stroke of a pen like UPX and OTrain was.
This amount of money for a little stub of a non-rapid {and rest assured it WON'T be rapid transit} would be comical if it wasn't so obscene. This money seems like the City has built bureaucracy, corruption, and incompetence into the line before shovels even hit the ground. Let's say this Union section costs a billion, although there is no reason it should, and the Cherry tunnel costs $200 million, that leaves a whopping $2 billion unaccounted for less 3 paltry KM. How many fingers are in this pie?
This is scandalous and if it even comes in at just half this price it will still go down in history as this planet's most expensive streetcar. If this goes ahead, I hope the City will never bitch about transit funding again but, unfortunately after the politicians and politically connected businesses have gotten their share of the largess, it will still be the long suffering transit users of Toronto that will pay the price.
