A little reminder about train prices

i mentioned a while ago about the cost of train travel and that I paid a little under 12€ for a return ticket to Porto and back. Well I am in Liverpool and I got the train down to Lisbon to get my flight to Liverpool. My return this time was 18€ and that was for a return journey much further than my previous trip but remember I am a Senior here in Portugal not an OAP. So I hope this reminder gets to people who may be taking a journey by train.
