Ironically, up north , the nearest line to Belfast international was mothballed a few years ago in order to improve the other line North . Every now and then a letter appears in the paper about how daft it is to not have a railway link. I find it insane that there has been no concrete plan to connect our airports to the rail system . North or South. It is almost deliberate. I wouldn't knock a rail connection to Shannon either. If you consider that visitors to our island generally come from bigger countries than ours, many would consider flying to Shannon, then an extra two hours on a train to dublin or cork on the train to be of no consequence whatsoever. A two our train ride in Russia is minute in distance, for example. I actually think there is a real need for more passenger rail, subsidised or not. Population trends indicate it.
