The bored section of the Canada Line with just the raw tunnel with liner and unfinished station boxes cost 55 million per km. When you added rails, electrical, and trainsets, the cost was more than double that.
If you use existing b line buses and do cut and cover to save even more money, there would be considerable savings over building rrt. Technology will allow brt to match train capacity as well, so really, rrt is not needed at this point, and is actually a big waste of money.
Also, when the buses are moving twice as fast in a dedicated busway, you need only half the amount of buses to achieve the same capacity.
