The Antequera-Granada high speed line opened 2019-06-26. When I search for tickets on the RENFE website, I find tickets up to and including 2019-12-15 for trains Granada-Madrid and Granada-Barcelona, but none after that (only MD rail replacement for the old line). I'm aware that RENFE are often very late in opening bookings after the December timetable change, but other AVE tickets such as Madrid-Barcelona and Madrid-Málaga are available for sale and have been for more than a week, so it appears to be something about the new line to Granada.
Is the high speed line Antequera-Granada still open after 2019-12-15 or is it closed?
