Hopefully it has dawned on the relevant parties that the proposed 10 minute interval DART timetable is impractical without unacceptable disruption to InterCity and longer distance users.
Ironically there is little benefit for DART users either as the reduced turn up and go waiting times are substantially eroded by increased journey times. More congestion and smaller peak hour trains would further erode any residual benefit for DART users.
Hopefully the effort will now turn to improving services for all users and in particular to the elimination of half-sized DART trains at peak periods. Better alignment of commuter services with the existing 15 minute interval DART and upsizing some of the DART trains would be a big step forward.
Any significant changes in frequency, other than on the already speed restricted section between Connolly and Grand Canal Dock will require additional tracks and/or overtaking facilities if some degree of service quality is to be maintained.
