I take the 29 Dufferin bus on a regular basis, commuting to and from work. It's an essential line for me and for other Torontonians, and I do quite appreciate its existence. The thing, though, is that the buses of the 29 Dufferin clump up badly and leave the line underserviced for long periods, and do so badly that Toronto transit expert Steve Munro devoted a category of his blog to explore just how it goes badly. Two nights ago, I saw three buses clumped up; the morning after, four.
