The bus network is being improved and this is very welcome. Newer buses are very comfortable and are competive vis a vis cars - you have Wi-Fi, power outlets etc and it is safe to work or use your phone, as opposed to being at the steering wheel of a car.
The LUAS is an attractive mode for travel - people like being above ground, with easy access. The line to Lucan should be prioritised and a LUAS to Finglas/Swords/Dublin Airport would be better than an underground Metro in a city the size of Dublin. Overground feels safer and this would help to reinvigorate areas of Dublin City and County.
The Dart is still one of the fastest options. Extensions to Maynooth etc, will make a marked difference and will help residents, workers, students and tourists. There is a sense that the fleet/line is old and unsafe, so options to increase a sense of safety are needed.
Commuter rail is a way to reach out to the greater region. Pricing needs to be revised. It is much, much cheaper to get a bus to Maynooth than a train to Kildare town, even though both are close to Dublin.
