I was surprised to see a discussion of overcrowding on a Westport-Dublin train appearing on the WRC thread.
Leaving that aside, I have just read the 2 Irish Times pieces (Friday Aug 23) on overcrowding. They refer to experiences on one service, the 0945 from Westport. Loads of human-interest stuff but no attempt to find out whether severe overcrowding was rare, occasional, or typical. Also one might think that before a journalist went on with the "why don't they put on more carriages?" thing, that they might inform themselves about the nature of modern trains, which are multiple units and cost millions and you just can't magic up an ould carriage and hook in on.
Of course the real reason for the overcrowding is the chronic inability of Shane Ross, the NTA, The Dept of Transport and no doubt other bodies to make investment decisions and actually implement them.
