For anyone of my age (50) these ticket validation measures are just the latest in a long line of expensive, poorly thought out ways of trying to replace staff at stations. I have lost count of the enormous numbers of different ticket barriers tried out in the Dublin area over the last four decades. Possibly the worst aspect of this latest attempt is the way that the most ignorant, badly motivated staff seem to have been placed at the barriers to 'help' passengers who experience difficulties.
