The lighting design for Green Line Station in Dubai, UAE, besides responding to functional and maintenance requirements, also augments the three visual personalities of the station — the passenger experience, the far view of the station, and the visual experience for the drivers on the adjoining highways. We developed a dramatic yet respectful lighting scheme for the Green Line Station that would attract both travelers and visitors. A monochromatic wash of light sweeps though the terminal as a train arrives and departs. When a train is not in the station, the exterior shell emits a white glow; a gradation of colored light pushes through the station gradually as the train arrives and trails out as the train departs. The concept for the lighting scheme comes from the pumping motion of a piston in steam engines.
