As for the 504, yes, it’s a mess. I am working on a large collection of vehicle tracking data for a series of articles on the evolution of service on this route over past years. What is abundantly clear to anyone riding the system is that managing for headway is a myth, and short turns to keep operators on time are more common than ever. Meanwhile the King route supervisors cluster outside the John Street Tim Horton’s in an obvious display of wasted manpower.
