Underground stations and transit hubs often have little in the way of daylight. A new transit hub in New York has tried to combat this with a specially-designed artwork-cum-skylight. The atrium of the Fulton Center features a huge kaleidoscope-like dome that pulls light deep into the building.
Rail infrastructure has a tendency to split cities into two, beyond just its physical route. A station in Denmark, however, will use clever design to negate any such sense of separation. Vinge Train Station will use an undulating concourse that allows the city to flow seamlessly across the tracks.
