FEVE Oviedo to Cabañaquinta/Collanzo?

Does anyone know if you can still travel by FEVE from Oviedo to Cabañaquinta or Collanzo? It was recommended on a thread from 2013, saying that there were some beautiful walks around there but I am using the FEVE timetable section of the RENFE site and nothing is coming up. I have searched online and can't find a definitive answer, so wondered if anyone knew.

Thanks in advance.
