Ms Anne Graham:

We hoped that we would not have to make such extensive service changes. When one begins operating through a very sophisticated signalling system throughout the busy city centre, one must operate it for some time to see what impact it has on other transport services. One can predict what may happen and that was part of the management programme we put in place in terms of trying to improve the infrastructure on the quays and in other parts of the city. One predicts as much as possible but the big test is when it is operating and in service and one can tweak the signalling system to try to make improvements and, ultimately, make changes to the services in order to improve the system overall. I do not agree that there was chaos. Rather, it was part of the learning experience of moving a significant piece of infrastructure into the heart of the city centre.
