I think we need to get back to reality when it comes to articulated buses. Cities across the country, most of which get far more snow than Toronto, run arctics with little issues. And I've been left high and dry by standard 40 foot buses because they've gotten stuck in inclement weather.
Yes, the arctics Toronto got back in the 80s were duds. But they were built 25 years ago in the USSR! The Soviet Union was not known were their auto workmanship qualities, and the technology with arctics has improved to improve safety, stability, and reliability.
I think the real reason so many here are so against these buses is that they see them as a threat to our streetcars, which is ridiculous. Despite what Boogyman Ford says, they are not going anywhere anytime soon. We've invested too much in completed infrastructure over the last couple of decades to simply tear them out and replace them with buses. Plus once the new LRVs start making rounds in the next couple of years turning our current antiqued tram routes into ultra light rail, there will be no turning back. No, articulated buses would be used mostly along suburban arterials with high passenger volumes and higher order express and BRT lines as well.
