Cannot.
NO, SNCF in FR will/vcannot help you. RENFE=de spaanse sporen, has its very own and hardly shared IT-system.
It should be doable in Sants=main station in Bcn=BUT use right windows.And check as plan B when next train will run after yours. EXITing at Sants may also take quite a while as you have to find someone who is willing to open a gate for you.
SO; RENFE has its own system-and in PBou this should also be possible, and be less busy. How much time you have there?
(sorry, but just to be NL-rude: het gebeurt vaak zat in ESpana dat personeel geen sjoege heeft van hoe/wat en dan maar zegt dat trein vol zit)
Ahh, thank you so in Port Bou it should be possible? They are not too “small” doing this?
Is there a France part and a Spanish part in the station?
I can make it into a 1.5 hour stop over if I want to Guess that would be enough.
Dutch reply @mcadv dan hoop ik dat ze het wel snappen in PBou, het lijkt me niet een groot station ? ..
Portbou heeft een RENFE-loket en dat zou inderdaad reserveringen moeten kunnen verkopen.
