I commute from drogheda to dublin 3 days a week (it used to be 5..) it is tough going but the service in the main is reasonably reliable and there is a great range of trains in the morning. I suppose the main gripe I would have is the lack of space, I mean surely irish rail realise how many people use the service and longer trains/extra carraiges would make a hell of a difference. It is crazy trying to get on a train in the evening, it does seem to bring out the worst in people !!
The price difference is crazy and it bugs me that they increase the cost of a ticket on fridays !! it is another example of rip-off ireland that said the annual ticket works out fairly reasonable for regular users of the train and it has tax benefits too….
My dh uses the Train somedays he always gives out that you cant buy a weekly ticket on the Automated machines and only at the counter, which the other day there was nobody at counter.
On a friday you have to buy a 5 day return ticket rather then the normal 3 day return ticket, so Fridays ticket is about 4 or 5 euro more expensive.
