Separating roads (1986) Peter Jansen & Matthijs van Dam
Beyond Graskruid metro station in Prins Alexander, the metro line splits into Line A, direction Ommoord-Binnenhof, and Line B, direction Nesselande. These lines split in the middle of the green Albert Schweitzerplantsoen. Because the metros have to make a turn, they keep to a certain speed. Artist duo Peter Jansen and Matthijs van Dam have based on that speed gradient determined the colors of a V-shaped metal plastic, which is placed near the junction. In the park, sixteen three-sided metal tubes, each 7 meters high, have been placed in two converging lines. The outwardly facing sides of the tubes are light gray with a signal yellow cut at the top. The other sides are orange-red and blue, colors that refer to the former color scheme of the RET and its metro trains. When the metro goes through the bend, this creates a plane with white, blue or red lines. Jansen also called these colored transitions a kinetic effect.
