The reason the Northern Line is at capacity is that there are a number of train types using the line at different speeds i.e. trains going non-stop to Drogheda, non-stop to Howth Junction or stopping at every station en route. Trains to Dublin airport could easily be accomodated if they ran non-stop to Howth Junction and then stopped only at Dublin Airport if they ran 2 minutes behind Trains running to either Drogheda or Howth Junction that didn't stop at each station.
Getting a connection to the City Centre from the airport is the objective not operating a train that becomes a Dart as soon as it hits trhe northern line; do people in Raheny have a god given right to a no-change route to the airport or do people in DCU have a similar right?
I also question your usage patterns on the North Commuter rail belt which excluding Swords is a series of quaint but small villages in the greater scheme of things. Look internationally there are very few international cities with a similar population to Dublin and none that I know of with similar development patterns that have ever spent this scale of expenditure on an underground rail link that wasn't a 5kms or less project interconnecting two irrationally split rail systems.
I would love to see each kilometer of the metro be analysed on cost benefit grounds and each station's projected passenger numbers as a proportion of the local population to see what contribution each station makes to operational revenues.
nice point. one small problem. trains going non stop to Howth junction run at a frequency of about 1 every global depression.
there have been 2 CBAs done for MN.
MN costs are in line with similar projects in European cities.
In 10 yrs time the mortgage type payments will be peanuts relatively speaking.
rail users Oirland seem to have such a fetish for mainline trains they can skew any logic to justify their schemes. not impressive.
