Mr. Hugh Creegan:

It happens. The thing is that when you want a permanent solution, even explaining to the public that on some services the route will start at this place and on another service it starts in another place is a bit of a confusing message to communicate to people if that is the long-term fix. That is why for the long-term fix, we can do the short running if we need it but, in general, we prefer to bring the service back to the start and then people understand that is a service every eight minutes or ten minutes, whatever it is.
