Jean - Now that I'm sleuthing around about this, I checked the link that Carrie included and it won't translate to English on the site - even though there's an English option up at the top. So Google translate it is - which isn't great, but I can get the gist of things. I read the translated site and then I did some dummy bookings for various days on my Trainline app. Trainline give a bus warning - due to storm damage, not accident damage - for the next few weeks and then it reverts to train departures.
Another thought - if switching your flight home costs a lot of time and/or money - a private driver, if you're desperate because the train isn't going and the bus won't work for you. I ended up booking one for one of my transits due to my (typically poor) decision to arrive in Malaga right during Semana Santa.
I booked Solhop transfers and their price for Cordoba to Malaga is 249 Euros, which is clearly a lot, but might be a good back up plan to have while you wait to see if the trains will be going.
