As said reservations are required on some trains (extra costs), particularly in Spain, France and Italy.

Barcelona - Paris is a long journey across France so you want to make sure you can arrive safely at your destination.

Book the required reservations in advance (possible without a pass) as if they're sold out you'll have to take a slower route. Fortunately looks like plenty of seats left on a February weekday. Your itinerary will be as follows :

- TGV Barcelona-Sants - Paris Gare de Lyon 09:28 - 16:12 or 13:25 - 20:18 35€

Which day are you going to Switzerland ? There are plenty of options on this route :

- direct TGVs to Basel for 29€

- TGV to Mulhouse or Strasbourg for 10-20€ + reservation-free regional train across the border

- etc.

Fortunately reservations aren't a thing in Switzerland (and optional in the other countries). You're always allowed to board.

I'm not sure whether you can buy a paper Eurail pass in Barcelona. You could call Renfe (+34 91 232 03 20) to ask in advance.

You can buy a mobile pass anytime though, also after arriving in Spain.

thanks very much for the advice and info..will do.thanks again....
