Ah. Another one of those incomprehensible SNCF sales systems
The (Lyon-)Nevers-Nantes Intercités is NOT compulsory reservation
But the train I’m to take tomorrow is listed as “fully booked” but yet I can book a fully flexible ticket for a later one. Which if it’s fully flexible would allow me to take the earlier one!
(I’m on Interrail anyway so this is immaterial anyway, but the system makes no sense)
@joepie91 this isn’t a compulsory reservation train. That’s the POINT. It hence cannot by definition sell out.
