We've never shut down the entire system during rush hour or on the weekend.Hmm i missed a couple events last summer because of closures on the on yonge line on the weekend. The closures were due to signal upgrades. Arent signals there for safety reasons?
Didnt we shut down a couple of weeks ago or months ago during rush hour due to a fire? Maybe not for day. But it has happened frequently. And almost everytime its for safety reasons.
