      i have already tried to float this on platform11.org . . .

      in the short term do we really need the whole interconnector: the idea of the interconnector as i understand it is to relieve congestion on the loop line bridge and allow a kildare dart service to run through to somewhere sensible. can’t these two aims be achieved by building a short tunnel from spenser dock to a new station underneath pearse and using the phoenix park tunnel?

      so, you build a four platform station under pearse along with a shunting tunnel and connect that to spenser dock with a two tracks. the kildare dart and the maynooth dart will run from under pearse and via spenser dock, the current dart will stay going along its current route.

      obviosly, the interconnector would be better, but this would be much cheaper, the tunnel is only a quarter as long and doesn’t go under so much so there will be less of inspecting peoples homes and paying them compensation if there delft is broken.

      the two problems with this is that pearse isn’t stephens green and it doesn’t add capacity between heuston and stephen’s green, but the figure of eight luas proposal, running past pearse would help with this.

      In 1998 there was a proposal to create a central rail terminal on Spencer Dock complete with inter-connector from Barrow Street allowing Pearse and Tara to return to more urbane uses and to cut down on the diesel electric pollution. This was taken up by the Dublin Chamber of Commerce and was supported by one of the major political parties, all prior to Spencer Dock becoming the site for the Conference Centre (obvious).

      hey shadow we registered the same month, cool!

      you mean that there would be an interconnector from the southern dart line at Barrow St? How would it get across the river, a bridge?

      and you got two highly qualified structural engineers explaining to you why it is not a good idea in term of costs versus return etc. Just because they did not give you the answer you wanted does not imply you were snubbed.

      To add my own perspective, the purpose of the Interconnector is not simply to connect Connolly-Spencer Dock and Hueston together so we have have a connected rail network in the city – if that was the case it would be a huge waste of money as the Park Tunnel route could do just this. This is how it was first marketed, and is sadly how Brennan is stil view it and it is much more than a DART conneting line.

      The purpose of the Interconnector is to move 60,000 per hour though the city centre with intermediate stops between Heuston and Spencer Dock as well as make conections with all other modes. The Interconnector is only part of a Dublin Rail Plan which will allow people from Newbridge to travel under the city centre and on to Drogheda allowing them to get on and off at several stations in the city centre. The Maynooth commuters have the same option, but going to Greystones instead. We are talking about a very high-frequency commuter rail network serving a vast hinterland were the current option for most commuters is to drive. The Dublin Rail Plan will have the capacity to transfer 25 million people onto public transport per annum and deliver them at several points in central Dublin. Each DART unit can carry 1200 passengers – the Interconenctor allows DART train running at high frequency to get to places like Kildare, Dunboyne, Maynooth and Drogheda – just think how many cars that will take out of the city centre.

      Bearing in mind that the main function of the Dublin Rail Plan/Interconnector is one of a car congestion buster – your mini-connector, will like the Airport Metro do little or nothing to solve this problem. This is why railways are to be developed – to provide a real alternative and not just to join them all together for the sake of it like some massive Hornby Model Train set.

      The Interconnector and the Dublin Rail Plan is quite simply brilliant in its design, scope, massive passenger capacity and potential to transform the city of Dublin and indeed a huge part of Leinster from a giant carpark it is now and will continue to be if Seamus Brennan gets his metro from the Green to the Airport serving areas of low car ownership and already excellent bus services.

      This Interconnector is such an important project it should be developed in full. What you are suggesting is no better than when Mary O’Rourke got out her crayons and a map of Dublin and decided that two broken LUAS lines was intergrated transport. We have to get out of this mentality in this country and do things properly once and for all. Enough half-assed transport projects already.

      Of course not. It is merely Irish Rails dick extension. They are looking for too much and as a result, will likely get nothing.

      The proposal included a tunnel 1.5 kilometres long arriving at an underground rail station with vertical connectivity to buses and other ground-based transport.

      sorry P11 Comms, i didn’t mean to
      imply i was snubbed, i was just referencing the other thread i case people wanted to see what was said there.

      nor of course am i against the interconnector and of course i am very pro rail and want all the things you say, but, if the only benefit from the whole interconnector is to allow people to get from Newbridge to Drogheda without changing trains, it is worth asking was the relative cost are.

      so here is my question again, what is the added benefit of the interconnector relative to a short tunnel from pearse to spencer dock apart from allowing people to go from maynooth to greystones without changing trains?

      oh and don’t be so pompous.

      I think that could also be called a two phase metro project, i.e. build the first phase as you say and then funds permitting finish the job. 😉

      shadow, you mean there was an underground station at barrow st?

      No the proposal was to reengineer Barrow Street to allow for a cutting to a tunnel which would re-emerge under Spencer Dock.

      but then it wouldn’t have passed under pearse?

      how were they planning to split up the routes?

      It was a theoretical proposal. Pearse and Tara would be retaken by the city.

      So, given that noone is so sure what the interconnector adds to the phoenix park tunnel connected under the river and given that seamus brennan is convinced we need a metro to the airport and given that turning around a tunnelling machine at stephen’s green will be expensive and awful here is my new plan: the metro line goes swords, airport, blah blah blah, broadstone, o’connell street, stephens green, pearse, and then spencer dock and hence onto the existing suburban network parts of which could then be electrifies. trains from the airport would go straight through the city centre around via spenser dock and then out along either the maynooth line or via heuston to kildare.

      this way the tunnel starts and ends out of the city centre, the trains will run through and don’t terminate at an underground station, travellers from the airport can get out at a variety of city centre stops and so can travellers on kildare and maynooth dart lines and if you really wanted you could travel from kildare or maynooth to the airport. it would also intersect everything.

      i will also post this proposal on platform11.org so people wanting to tell me that i am probably the sort of person who enjoys travelling on trains between cities and should therefore shut up can go and say that there.

      If the Metro was extended from Swords to Balbriggan (Could be done overland as there is bugger all out there you could connect it to the Northern line so people travelling to the airport from the North (if you look at the long term car park note the amount of yellow reg cars) and those in North County Dublin, Meath and Louth (myself included) could change trains to get to the airport.

      Could also open up development land in North Co. Dublin. We need lines to link up with existing ones, not just terminate on its own.
