When the upgraded Enterprise started in1997 it was routine to reach Drogheda in under 28 minutes with under 26 minutes not particularly uncommon. My fastest trip was marginally over 24 minutes. So 47 minutes is almost double what uncongested infrastructure would deliver.
The amount of slots north of Connolly allocated to DART is already grossly disproportionate to the traffic carried, the revised timetable greatlly increases the imbalance. Even at the busiest point immeduately north of East Wall Junction DART only accounts for 58% of the numbers travelling.
Interesting this timetable proves my concerns about DART underground - without additional physical tracks trains more DARTs mean more congestion and slower journey times. This is not a strategy that will result in extra business but wiil simply drive people away.
