The railway station is inscribed as an interference in this linear landscape. This principle of triangulation contaminates the protective envelope which, through its aerodynamic aesthetics, constitutes the first signalling sequence: this is not a building, nor a façade, but a deflector. The fusion of the embankment and the envelope, in a unique dynamic, generates a precise insertion of this landscape, infrastructural, signalling object...
