Metrolink - Alternative Routes - See post one for restrictions.

I’m sorry, but I really do not understand your point at all. Are you proposing that the metro utilise this alignment as part of its route? That is a completely stupid idea.

The GL alignment would swing the metro wayyy of course and the correction needed to bring it from Liffey Junction back up towards Collins Ave would be stupidly expensive and wildly unnecessary.

It would unnecessarily elongate the journey from Swords, the airport and all of the as of now UNSERVED areas of north Dublin toward the city centre, and cost far more money than just digging the straight line tunnel. I say UNSERVED, because Drumcondra - the dead and buried horse which you so tiredly keep flogging - is currently already served, and will in the very near future be even better served, by direct trains to the city centre.

The cost is another element which you seem to forget about too. Digging the tunnel is arguably the least expensive part of building a metro once the TBM is in the ground. Resurfacing the line at Broadstone to use the 1.5km of track (yes, only 1.5) to then have to dive underground AGAIN at Liffey Junction, would mean the Metrolink project would need 3 TBM sections instead of just 2 as things currently stand and make each one less efficient and less likely to pass a CBA.

As well as this, where do you propose to reroute the GL on its way to Finglas?? A tram is the perfect model for Finglas - metro would be complete overkill - and a metro is the perfect model for Swords - a tram would be severely underperformative. You hardly propose rerouting the metro to Finglas and the GL to Swords do you…?

Your argument about the lines being too close and affecting catchment is also completely moot. The stations are far enough apart, as @Consonata has demonstrated, to support seperate catchments. Luas has stops much closer together for local service and Metro has stops spaced farther apart for a more express style service. The alignment spacing does not matter if the STOPS can be justified, which in ALL cases I (and I think everybody else on here would agree with me), believe to be the case.

Also if catchment at the two Cabra and Phibsborough stops are slightly affected, it’s not the end of the world. This northern part of the Green Line already serves TUD’s main campus at two different stops, a mainline rail and bus interchange, and will go on to serve the very busy suburb of Finglas, and a major Park and Ride facility in Charlestown with a promised increase in tram frequency from the 7.5 minutes you quoted, so I think it can afford to lose a few passengers at two of its more quieter stations and not face closure.

Finally I’m just confused about your consistency on this case of ‘building a brand new rail line so close to an existing one.’ You yourself have suggested very (VERY) often that the metro be built under Drumcondra Road instead and that the Luas Balgriffin Line be placed directly above the metro, on the street. This, if I’m not mistaken, under your logic is the direct duplication of an existing rail alignment with a new expensive one… isn’t it…?

I think I speak for everyone - posters, readers, and moderators - when I ask that you please give it a rest on the obsessive Metrolink alterations. It may not be a perfect plan but it is a great one and it’s the one that is in ACP as we speak - it is not going to be changed. You have been asked countless times by mods and other members on here to accept that and have been given counter argument after counter argument proving that the current alignment is better than all of your suggestions but yet you keep harping on about Drumcondra and the Green Line’s alignment. Please. Just stop.
