LightRail is the world’s first subway-responsive light sculpture. By visualizing the real-time movement of underground trains along Market Street, it will transform San Francisco’s main artery into a scene of wonder and awe for millions.
Two LED strings in the center of Market Street will stretch two miles from Van Ness Avenue to The Embarcadero. The LED strands will be suspended safely above SF MUNI lines by anchoring into existing light post infrastructure. They will use BART and MUNI APIs to brilliantly illuminate the movement of underground trains. After BART and MUNI have closed, randomly distributed small pulses of light will move along Market Street, simulating the passage of pedestrians. The piece will thus be a celebration of the many sustainable modes of transit that make up city life.
