This is a debate that has been going on for a long time and it is the possibility of opening the metro on weekends at night. It would be important to know if it is a positive measure or too expensive for what it reports to the city.
We do not need too high a frequency, but we do not need more than 20 minutes, because if we had to change trains, it would drive many people back. It would be interesting,
if someone knows a little more about the subject, to know the cons that this would have, because I believe that currently, there is no metro in the world that is open at night, so I do not think it is an easy task.
