Shane Moynihan (Dublin Mid West, Fianna Fail)

In somewhere such as Dublin, for example, where there are consistently large events on in the city centre, how quickly is Mr. Hann able to go back to the NTA and have an updated weekend timetable, stating that Dublin Bus has seen a steady increase in the number of people going into the city centre, that it was 100 and it is fairly sure it will go to 120? How quickly can that be turned around into an updated timetable? How long does that take?
