A return trip from belfast to dublin (obviously you would only need the dublin-belfast part) is as low as £10 but im not sure if you can book online and print your ticket from home. Check the Translink NI website for that. Otherwise, you will have to check the Irish Rail website as the north and south of Ireland are two different companies (although they do work in conjunction on the Dublin Belfast line). From there, check what a single ticket to Belfast will be. Id certainly recommend taking the train for the trip to belfast from dublin as it runs (mostly) at 90mph, but the train from belfast to derry is a different kettle of fish! Here id recommend you take the express service bus instead. Its at least 30mins faster and on top of that theres huge engineering works starting in the summer on the derry rail line. As far as i know the line will be closed at Coleraine and you will be put on a bus for the remainder of the journey making the trip even worse. When you get to Belfast (Central station) by train either get a local train back to Great Victoria st station (its only a 10min journey, 3 stops away) or grab at taxi outside and ask to be taken to the Europa Bus station (again this will take no more than 10mins and cost about £5). Once there, buy your ticket to Derry. The bus goes a much more direct route and is quite comfortable. Any enquiries about these buses or northern ireland trains are all via the Translink website, or this number: 02890666630. They are the same company.
Forget Translink/NIR completely for the Dublin - Belfast part of the journey. Their website doesn't allow you to book online, and buying their web fare means you get a voucher *posted* to you (no, I'm not joking - I'm surprised they're not using carrier pigeon...).
www.irishrail.ie is the place to go to book your ticket. There are single fares available from Dublin - Belfast there for as little as 10 Euros. Plus you don't need to get anything posted to you. :-)
Like horizon says, getting the bus from Belfast to Derry is likely to be more convenient in August, given that the rail line between Coleraine and Derry is going to be closed from July onwards.
Even without the planned rail closure, the bus from Belfast to Londonderry is quicker. Go for the 'Maiden City Flyer' route or the Express service via Dungiven. Avoid the service that goes via Omagh, it takes much longer. Journey time is about 80 mins. Buses leave from the Europa bus centre in Belfast. Also, the bus terminal in Londonderry is more convenient than the train station as it is closer to the city's attractions.
The fare is about £10 return in memory serves, check Translink.co.uk for up to date schudule and pricing.Edited: 14 March 2012, 17:09
They want to cover the trip by train. So the best advice is to get the train to Belfast and the express bus from the Europa bus centre in Great victoria street to Derry. I wouldnt fancy a bus the whole way from Dublin to Derry! Anyway, the bus you must get from the Europa is the Goldline 212 Service. Look out for that.
