What kind of rolling stock is used in Ireland these days,about 20 years ago i got the early morning service from rosslare to Dublin which was loco hauled with mk 1,s, then the express from Dublin to cork. Has it gone the of this country with units and no windows to hang your head out of.
The only locomotive operated passenger services are those from Dublin to Belfast, which are Die Dietrich (1996) built pushpull sets, and the Dublin-Cork route, which is operated by CAF built (2005) mkIV pushpull sets (not related to the BR mk4s). Both are powered by 1994/5 built GM 201 class locos.
All other passenger services are worked by railcars. The Rotem built 22000 class work most of the Dublin based Intercity services (apart from those mentioned above, though they do work one or two Cork turns). Outer suburban Dublin workings are mainly either Tokyu Car (2000) built 2800 class or CAF (2003-5) built 29000 class railcars. Non radial routes and Limerick/Cork locals are worked by either the Tokyu Car (1994) 2600 class or the Alstom built (1997-8) 2700 class railcars, as is the Ballina branch.
With the exception of some ex-BR brakes converted to steam heat and generator vans, there were never any mk1s in Ireland, nor was the term mk1 ever used. The coaches you are referring to are probably the 1963-67 built Cravens, which in terms of structural integrity, age, etc have more in common with a mkII. These were withdrawn over the course of 2006 and ten have been preserved in Dublin by the Railway Preservation Society of Ireland (RPSI) for use on excursion trains. Predating them were a variety of carriages built in the 1950s (Park Royals, Laminates, older wooden-bodied stock) but again these were never known as mk1s.
The mkIIds were withdrawn over 2007/8 (two preserved by the RPSI at Whitehead), with the mkIIIs being withdrawn in 2009 (apart from a brief reprieve to work a one-off railtour for charity in 2010). The secondhand ex-BR mkIIa/b coaches were withdrawn back in 2003.
All in all the system has come along way in the last half a decade or so, with efficient railcars allowing many routes a greater service frequency than ever before (Dublin-Sligo now has a train every two hours, there used to be only three a day!).

As for the price of Rover tickets, there is due to be a fare increase (on average 3%) from March 1st 2011 so it's probable the prices of some of these tickets will have risen slightly by the summer.
