From this station to the next one, Ciudadela, the machine must bore a tunnel of about 1900 m and the speed will remain around 20 m/day, therefore it will reach the wall of the third station approximately in February 2018. If all of this is correct the tunnelling will end in April 2019 but the detailed works could continue until 2021...

Erratum


Everything I've said about the tunnelling has been debunked by someone who has more information. Ramos Mejía will be reached hopefully in July 2018!
