It's possible to do, sort of, but it's not necessarily easy and there are a number of transfers involved. The basic plan is to go from Rome to Liverpool by rail, then take a ferry from the Liverpool suburb of Bootle to Dublin. However, getting from Rome to Liverpool will have you on at least four different rail systems (add two more - Thameslink and the Underground - if you don't want to walk a half-mile or so in London); you'll need to get on yet another rail system (or a series of busses) to get to Bootle, and then you'll have to walk to the ferry dock.
For a comparable journey in the US, you'd be far better off flying ... it wouldn't be much if any more expensive and you'd get there faster. My understanding is that rail travel in Europe is a much more viable option than it is in the US, but I still wouldn't absolutely rule out just hopping on a plane.
The flight time from Dublin in Ireland to Amsterdam is approximately 13 hours and 9 minutes. The exact travel time will vary as it depends on factors such as weather conditions, flight speed, refuelling stops and delays. Your airline can provide additional information.
No. Ireland is an island so there are no trains from it to other countries. Flying to Rome would be fastest. You could go to Wales and go by train to England and get a train from London to Paris through the Channel Tunnel and then get a train from Paris to Rome. Paris to Rome by train takes just over 11 hours.
Night Boat to Dublin was created in 1946.
There is no train from Dublin to Waterville. You could get a train to Tralee or Killarney in county Kerry, the county that Waterville is in.
Dublin is in Europe, so you could say the answer is zero. The nearest European country would be Wales, which is less than 2 hours by boat. To mainland Europe, which is probably what you mean, it can be done in less than 2 days. There are no actual ferries from Dublin to any mainland Europe country.
There is no direct train journey from Dublin to Glasgow. There are a wide variety of ways you can make part of the journey by train. You could get a train to Belfast and then a ferry from Larne to Stranraer, and then a train to Glasgow. You can fly from Dublin to Prestwick, and get a train from there to Glasgow. You can get a ferry from Dublin to Liverpool and travel by rail to Glasgow that way. As there are many different options, then there is no single answer to your question.
Yes. There are regular train services from Dublin to Cork all day long.
