The Renfe Talgo fast train from Peñiscola to Barcelona only takes 2 hours to travel 250km, you get a reserved seat and they’re  OK confort wise. It cost 80€ return for Mom & I.

There are 2 small tv screens in each carriage which play movies but its pretty difficult to see them clearly, the headphone sockets are rubbish so you cant hear the movie either.

The only power outlets are in the restroom so I couldn’t charge my tablet when the battery ran out 🙁
