Re-open Rosslare-Waterford Line, and join routes in a loop

This week the Phoenix Park tunnel reopened, which now means trains that used to only be able to travel to Heuston Station, can now travel to Connolly Station and beyond.

Over the years I have oft taken the train to Rosslare, which starts at Connolly Station, and this got me thinking.
A few years ago the line that linked Rosslare Harbour Train Station to Plunkett Station Waterford was disgracefully closed.
With Iarnroid Eireann having to cut back even more due to a shamefully low subvention from the government (A mere fraction of what state train companies in Germany Holland etc get), so any area where efficiencies can be found, should of course be grasped.

With the re-opening of the tunnel, it has poppede one such efficiency measure into my mind.
 Why don't we combine the current Heuston-Kildare-Athy-Carlow-Bagenalstown-Kilkenny-Thomastown-Waterford line, with the Dublin Connolly/Tara Street/Pearse Street - Dun Laoghaire - Bray - Greystones - Wicklow - Rathdrum - Arkloow - Gorey - Enniscorthy - Wexford town - Rosslare lines?

For this to happen, as well as using the newly reopened Phoenix Park Tunnel, now closed stations in Wexford would have to be reopened.
These would be: Bridgetown, Wellingtonbridge, Ballycullane, and Campile stations.

So A train would leave Connolly, travel the existing route to Rosslare Harbour, but THEN travel the old Rosslare-Waterford line, whereupon it would continue on what is the current Heuston Waterford route, but instead it would turn off before Heuston, onto the Pheonix Park Tunnel and onto Connolly.
there would also be trains heading the other direction - Dublin(Connolly)-Kildare-Carlow-Waterford-Wexford-Wicklow-Dublin.

This will allow greater connectivity on the rail line. Though of course it would be a quite longer roundabout way of getting there by car, you would now be ablle to get from Wicklow town to Carlow by train without having to take two trains and a LUAS.
It will also mean greater capacity on both the exisiting routes, with twice as many train stopping at Wexford en route to Dublin than is now the case.
A lot of people in Wexford have to go to Waterford hospital for appointments, and this too will help them greatly.

I know people will come straight back to me and say "Who's going to pay for it? It will lose Irish Rail more money as not enough will use it to make it viable!" etc.
The simple answer is NO efficiently run train service makes a profit, Deutsche Bahn in Germany, SNCB in Belgium are heavily subsidised by the state.
But this means goods and people can be transported efficiently from A to B, and overall leads to greater revenue for the country, as the positive spin off of more companies choosing to setup there because of the excellent rail links.

Thus it is long past time that the government started properly funding our rail network, so we can have more and speedier trains running, which WILL see many more people ditching their cars, which can only be good for Ireland trying to meeting it's obligatory carbon emissions targets!
