CP does not have a service to accompany minors. However, if the minor is mature enough to travel alone, CP does not raise any difficulties. Minors who travel alone, with a ticket, are their parents or guardians' responsibility.
Children aged three or less, when accompanied by their parents or guardians travel for free s long as they do not occupy a seat. If they do take up a seat, they have to pay half-price. If they are over 3 and under 13, they pay a half-price ticket on Alfa Pendular, Intercidades, Regional, InterRegional and Lisbon, Oporto and Coimbra urban trains. See Children - half prices for further details.
