Zefiros,
I checked for you on the renfe website and I am sure you have done the right thing in getting the schedule. It says it does not allow searching for train schedules after June 15, but it does not accept that day either. Until June 14, the morning and evening train are daily and the schedule changes in that in the afternoon on sundays. I guess you can call their number on the site because I highly doubt they dont know the schedules, it may be they are not available online yet. Good luck!
