Are these yours?
I know you don’t normally do this but…..I found a set of keys down the side of my seat at the window on the 5:15 from Westport to Heuston, I got on the train in Portarlington and only noticed them when I was getting off. Have a feeling they belong to someone who got off in Portarlington due to what what was left on the table, could have been any of the stations in between though all the tags seem local to Westport i.e. SuperValu, Tesco, Dunnes, Treacy’s pharmacy.. If they are yours I have left them with the Information desk in Heuston, contact them and they should be able to get them to either Portarlington, Westport or any station in between.
