Iarnród Éireann needs to take a fresh look at its operational strategy. Large, lumbering American locomotives designed to haul freight across the Rocky Mountains are used to pull passenger trains. The turnabout times for these locomotives can vary from one to two hours, thereby severely reducing the number of journeys each train can make daily. If Michael O'Leary can turn a Boeing jet around in 25 minutes, Iarnród Éireann should aim for a similar turnaround time.
