Has anybody ever come across the Institute of Engineers of Ireland's "Vision of Transport in Ireland in 2050" in which they propose building a rail link under the Irish sea connecting Ireland to Britain and Europe.
Do you think this is affordable (both as a project, and to keep running in the long run). Would you take a 3.5 hour train to London instead of a flight, and a 5 hour train to Paris?
Before you decide, consider this. Did you know that the Dublin-London route is the busiest air route in Europe, and second in the world? Also could it be that many people would be willing to exchange their plane tickets for a train ticket. Considering that (1) between travel to the airport, (2) having to be in the airport 1.5-2 hours beforehand, (3) another 30-60 minutes between boarding, going through the scanner, walking to your flight port, boarding the plane, and 30 minutes for it to start on the runway, and (4) another possible half an hour trying to get out of the airport on the other side.
This is very stressful and means that a flight to London is probably really 4-5 hours, and about the same for Paris. So would it be better to have an easily accessible International train station in the centre of Dublin (linked up with buses, metro, luas, interconnector etc), which would bring you right into the heart of London or Paris- than all the time and energy that goes into air travel. Simply buy a ticket, show your passport, hop on the train- and enjoy the journey (and the scenery of course).
(p.s. if Michael O Leary is reading, don't worry i'm not running a Tusker tunnel company out to get at the airlines!! )
