If you want to pay for it, then do it the way you want. It's that easy. How's it coming so far? In the event, it will be paid for by private enterprise, it will be 'off the shelf' and it won't use side valve hand crank engines and 6V batteries. Why did VIA have to choose what it did instead of using forty year old designs? Steam engines would have been much better! And why replace the older streetcars with newer LRTs? And them buses, eh? Nothing wrong with the old GM two-strokes.
Flip the question over, and don't be so Toronto for a moment: Why is the 'metro' type vehicle
by far the most popular transit mass people mover system in the world right now?
Here's cities that have adopted the Alstom Metropolis
alone! And there are four major competitors and lots smaller who build them:

And then there's airplanes. Nothing wrong with DC-3s. What's with all these new fangled jets anyway?
There is irony though: Toronto was actually a leader with the SRT. And blew it ever since.
