The architect Klaus Hornberger presented the train station as a gateway to the city. The triangular geometry of the building was already set about a hundred years ago by those who planned the tracks. With the pedestrian passageway at city level the railway station connects the two quarters of Metalli and Grafenau. At dusk, the light installation by artist James Turrell transforms the imposing station building into an ethereal glowing object. And that by only using the three colours red, blue and green and the resulting shades emanating from their flowing movements.
