Five minutes at Chamartín

8:15. We are finally leaving the stressful, dark tunnel and the train is approaching the Chamartín station. The sky is pink and I am thinking that the weather forecast must be wrong as it seems we are going to have a nice day. Enjoying it like every day, I watch people to leave and board and other Cercanías trains entering and departing the station. At that moment, I look at the Cuatro Torres and the tops of the skyscrapers are slowly disappearing in the advancing fog. In less than a blink of an eye, everything is sunk in thick white milk.
