Hello,
tomorrow I want to travel from Marseille St Charles to Madrid-Puerta De Atocha with Train RSC 9731.
Because it was planned at short notice I went to the ticket office at the train station in Marseille. Unfortunately, it was not possible for me to reserve a seat for the train tomorrow. I could only buy a ticket with a seat but since I already have the Interrail ticket I only need a seat. Unfortunately, there is no way to book the seat reservation online or via the app.
What am I doing wrong? What option do I have now?
Best regards, Max
