The Dart+ project is a good one and is much needed along the Maynooth line. It must be remembered, however, that not all journeys in Fingal are to the city centre and closing the level crossings will have a huge impact on the population of Dublin 15 (and beyond), who cross the rail line daily for work, family, school, retail etc. CM024 therefore is premature - a final decision on closing the level crossings has not yet been made and it shouldn't be seen as a done deal. Mitigation of impact will not be needed, if Irish Rail invest in signalling and if post-covid capacity reports show that a 24/7 closure of the level crossing is no longer necessary.
Reflecting the fact that many journeys within Fingal are not to the city centre, I support CM025 and CM027, both of which aim to increase public transport routes between Dublin 15 and the airport/Dublin 15 and Swords.
