It would have been far easier and less confusing if they had simply created another branch of the 72 that would only run between King and Commissioners. When the route numbering was changed it would also have made sense to have bitten the bullet and officially changed the routing so that the bus will go permanently to the King and St Andrew subway stations. This temporary change has clearly resulted in far more ridership as the 72/172 is now a very viable alternative to the (too often short-turned) 504 streetcar.
