I've not seen very many at all - the odd mid-day car perhaps. There's none out this morning.I've been seeing a lot of the new Flexity's on Queen lately running as 501.
Where did you see this?
It's probably 504, 509, 510, 512, and 514 cars, that all have to run down Queen East, and even Queen West to Bathurst to get to their routes, from the barn on Leslie south of Queen. Many are signed as 501s - and there's a never-ending stream of them at 6 AM or so, as service begins.
