Hi, there should be trains,

but you have to do with spanish railways RENFE. They do not share completely their timetable or often late. Check directly at RENFE the timetable. 

A quick check on OEBB and Renfe suggests there are regular services in the next few weeks so I assume Renfe are just being their usual tardy selves on releasing the new timetables. Just check once a week.

www.raileurope.com is quite good for Spanish timetables (instead of the les-than-optimal RENFE website). You can also set an alert for when booking opens. You can't book pass holder reservations there but you'll be able to check the timetable.
