Snappy Answers runs every Saturday afternoon. Send your questions, be they tough or trivial, to snappyanswers@torontoist.com. What's up with the longer-than-normal wait at Chester Station? I know the reason for the one at Coxwell; the drivers change. But at Chester? I'd been planning to email the TTC and ask, but I imagine you'll answer my question in a much zazzier way. Thanks, J.......
