Default High speed rail... feasibility study... maybe

From the proposed deal to restore Stormont
The Irish Government is supportive of serious and detailed joint consideration through the NSMC of the feasibility of a high-speed rail connection between Belfast, Dublin and Cork, creating a spine of connectivity on the island, which could be progressed as a priority.

Good news for Parsons or whichever consulting shop gets the contract to write that study to fill shelves and attract dust

Is there any practical possibility of getting current lines to 240km/h?

Because that would be a lot cheaper and still make Cork-Belfast possible in c. 2 hours.

Of course you still have to get across Dublin and that is where the real expense would lie.

I can't imagine there's enough demand for a greenfield line to the north and west of Dublin. Could there be enough demand for Cork/Limerick/Galway-Dublin Airport to make this a possibility? Most people would be traveling Cork-Dublin or Belfast-Dublin, not Cork-Belfast or even Cork-Drogheda or Belfast-Limerick. And we know the interconnector, whatever its status hasn't been planned for InterCity trains.

It's interesting that high speed rail comes up for discussion as the UK is leaving the EU. A cross border route between two member states would qualify for EU funding. A cross border route to a non-EU country wouldn't, though I'm sure some funding could be wrangled under the heading of "peace process".

Has anyone even thought about whether this would be a new route, or upgrading the existing lines? Upgrading would have the advantage that other services could take advantage of the higher speed tracks, and would probably be less costly, but would have the downside that high speed could get stuck behind slower service, delays could arise.

The rollout of high speed lines in Spain would be worth analysing. Some of their lines have quite low population density, and it's hard to see them ever being viable without massive government subsidy.

There is an election coming

Dublin Belfast is underserved it should have double if not triple the current demand, but due to the long dragged out peace process and now Brexit the uncertainty is killing it. You could justify electrification but only in conjunction with commuter services.

Dublin Cork does well but bear in mind some sections of the line see only a train an hour in each direction (Limerick Junc - Mallow)

Neither route has air competition so the end to end time is not critical, you could start with

1. Tunnel from Killester to Airport to Rush And Lusk (shared with all trains from Drogheda/Dundalk)
2. Enhancements to 200-225kph + selective 4 track/dynamic loops around stations
3. Diversion around Armagh to address the long standing routing of the Dublin Belfast route
4. Some 4 tracking into Belfast
5. Cut stops down to bare minimum Connolly, Airport, Dundalk, Newry, Belfast
6. 75 minute end to end.

Dublin Cork, if you could deal with the Curragh and Portarlington 200-225kph would be possible across almost the entire route, no need for a new line as there is little traffic on the current. Add in electrification and you would see a serious speed up

Mark: I would agree with much of what you say.

Dublin-Belfast through traffic is relatively low and hourly services are a pipe-dream, without the extensive capacity-enhancing measures you mention. Long-distance travel on the Cork line is far greater.

On the Belfast line, I think you mean diversion around Portadown rather than Armagh. Also there is a pretty unavoidable severe speed restriction at Drogheda, and the track curvature over a lot of the line from the border to Portadown restricts speeds quite significactly.

A proper high carbon tax should enhance the competitiveness of rail over road and also vastly enhance the attraction of electrification. After all we aim to electrify private car transport, which is quite a tall order.
