What IE didn't say is the line from Dun Laoghaire to Bray is closed from 24:00 to 05:00 to facilate testing of trains
Passenger numbers are crap and to be honest the only reason I used it last year was since the 12:30 service was normal fares while Dublin Bus charged €4. The normal fares thing is thanks to the RPA since I argued it with the suburban office last year and they changed it on the website an hour later,

Dublin Bus provide a service on nightlink that is very good and centrally located in the city and its fast and gets you closer to home in most cases, there was always the joke that certain routes got a better service at 3am than at 8am
I have travelled on late night DART every year the service has been provided and the passenger numbers on one train would be less than on a busy nightlink route, but the train carried 2 ticket checkers, 2 security and a driver all on overtime, Dublin bus its a rostered turn no overtime
Who fancies walking from Temple Bar to Pearse afterall you pass the nightlink stop on the way it can't work, Dublin Bus have cornered the market with a better product which has a 10+ year history
