Metrolink south of Charlemont

I am slightly less pessimistic than bk about DU because I think ML and the likely conversion of GL to ML will in fact spur on calls for more underground solutions. I also think that DART+ (especially SW) & fourNorth will seriously build the case for DU as passenger numbers coming in from Hazelhatch etc. increase to use up any capacity the PPT & Loop line can deliver (the latter not much really). Then we will have overloaded DARTs again and there will be no avoiding the obvious solution in DU, especially if fourNorth is in place.

You might be surprised to hear, but I totally agree with you. I think it is more of a case of difference in timing. I don't believe we will go straight into DU once DART+ and ML finish, I think we will have to live with them for at least a decade, for demand to increase (new housing developments to the West of Dublin) and build up to a level where we have no choice but to do it.

I think in the 2035 to 2045 period the focus will be on multiple Luas lines, fourNorth, Navan, ML upgrades on both ends. But as you say once Navan and FourNorth are done, the pressure for DU may well be there then.

Really it is a pity that we didn't build out the DART network over the past 30 years. We could have been at that point now!
