The upper platform hall, which runs east–west, is 321 metres long and consists of the arched, column-free, glass roof structure, which is supported by the two outer railway overpass structures. In the glass surface, a 2700 square metre photovoltaic system with a capacity of 330 kilowatts was integrated. The hall is between 46 and 66 metres wide and a maximum of 16 metres high. It consists of three sections, with the western segment 172 metres and the eastern 107 metres long. In between lies the 50 metres wide and 180 metres long north–south roof, whose barrel vaults with the main roof form a flat viaduct. Parallel to the north–south roof, the two "ironing structures" span the main roof of the platform hall and carry the north–south roof. These ironing structures contain 42,000 square metres of office space.
