Instead of spending 15 billion, how much would the following cost?

Upgrade Heuston-Cork:

200kph
electrified
all level crossings eliminated
station upgrades
bridges/tunnels all upgraded to allow 200kph all the time
Journey time for 266km to be 2h on limited stop trains, so 133kph average speed, including the stops

All to allow a mix of non-stop IC, limited-stop IC and stopping regional trains, for example:

Limited stop IC would stop as follows:

Portarlington
Portlaoise (end of stopping trains from Dublin)
LJ
Mallow



Upgrade Connolly-Belfast:

200kph all the way, electrified
Separate DART from IC
(put new tracks in tunnel under DART tracks?)
(or make the mainline a new line via Dub airport?)
Journey time of 90 mins - might that be possible with stops at Drogheda, Dundalk, Newry, where else, ??

I'm pretty sure all those questions are what a feasibility study could answer!

I don't know if it is just how the media are reporting this, but I understood that this proposed study was to look at all options, from removing pinch points and speed restrictions on existing lines, all the way up to a brand new high speed line. A review of the entire network along the Belfast - Dublin - Cork / Limerick corridors.

I am of the opinion that a strategic rail review should be carried out every 20 years or so.
