I'm trying to buy one way train ticket to Porto from Lisbon on January 1st. And I get this error message on their website
"WS1: No dia de viagem escolhido o comboio de ida não se encontra disponível para venda, pois não é possível assegurar a sua realização. Lamentamos os incómodos causados."
which google translates into
:WS1: On the chosen day trip train trip is not available for sale, because it is not possible to ensure its realization. We apologize for any inconvenience caused."
I also checked on the Christmas day and looks like I get the same message. I'm assuming I can't buy tickets online on major holidays? or does this mean the train might not run that day? Or do I just buy it at the station?
Thanks in advance!
