Hello, I am trying to reserve 4 train tickets for the TGV 9702 TGV INOUI from Barcelona-Sants to Paris Gare de Lyon on the 2. of August at 10:00 am. I think these reservations are only available as paper tickets.
If I try to make the reservation on the eurrail/interrail website it tells me that the amount of available seats is unknown. How can I reserve seats, if the website doesn't know how many seats there are?
Also I read on a different page that reservations for Spain can only be done at train stations, so how is it possible to do one on the website? I am very confused and would be grateful for some help.
