If you live in Gormanston you pay €5 a week, but the new plan is to charge €8 at further stations where charges are applied. Its a different company to the one currently used.
So 48 week year at €8 per week €384 which is 43% increase over the normal Dublin rail annual ticket of €890
I quite deliberately did my piece for TV3 from Booterstown car park, they tried to charge there before, it didn't happen.
