Well from the conversation with them, he said the train from Cork is a 5.20am not 5.30am so maybe thats changed and there's a train to arrive Portarlington at 7.30am. There is a train that runs straight through Portarlington at this time ,it probably is a Galway train so my guess is they're probably going to now have that one stop. However that would guarantee standing room only from Portarlington upwards
So its Standing for all Lilywhites onwards
