People are generally unhappy with the frequency and as of late, the reduced size of trains, with 2-car trains being used as early as 7pm.
One of the big problems is that not only is the frequency poorer than desired, it also suffers from erratic spacing, e.g. the 30 minute gap at 9am from Howth, partially due to DART having to leave gaps for longer distance services. The only section that can be considered to have a decent frequency is Connolly to Grand Canal Dock.
Luas generally provides a much better frequency.
