In some parts of the city, I haven't seen anything BUT low-floor buses for years. So all the buses I saw running during the storm were low-floor buses. I saw no high-floor buses operating during the storm. But I haven't for months ... so statements like that don't mean much. Personally the only time I've encountered them recently was on the 510 Spadina Bus!
If you look at the
Service Summary, the TTC only has 237 buses that aren't high-floor. Over 87% of the fleet is low-floor - therefore one would expect 87% of the breakdowns to be low-floor buses.
Further, those high-floor buses are only found in 3 of the 7 garages.
And if you dig deeper, the non-low floor buses are only used on Dufferin, Finch East (39, 139, and 199), Keele North, Middlefield, Nugget, Scarborough Center Rocket, Steeles East, Weston Road North, and Wilson.
If you don't use these services, and they aren't in your neighbourhood, then everything you see broken down will be a low-floor bus!
