Allé station are a reference to the lime trees that line the avenue above the station. Three stations, among them Nørrebro, were given

white glazed brick panels, inspired by the numerous monuments at the nearby Assistens cemetery. Angular panels such as those at Gammel Strand or colourful details on the bottom edges of the brick panels at Vibenshus Runddel station further highlight the design diversity.

KIT-BUILT STATIONS Overseeing architects at Arup were a key element in the Copenhagen authority’s mission to become carbon neutral by 2025. The new line seeks to achieve this in part by encouraging more residents out of their car and onto a more environmentally-friendly mass transit network. Now that it has been completed, Cityringen ensures that the majority (around 85 per cent) of Copenhagen’s residents will be within 600m of a train or metro station. During the construction, Arup approached each

station as being a gigantic kit of parts made up of a cost-effective construction system with individual modular parts that can be easily assembled, installed or removed as required. According to Arup, every element of the design had to work hard. Beyond their functional use as air vents,

the asymmetric, sculptural skylights allow natural light to flood the stations and in a similar dual-use approach, the lighting design is fully integrated with the architecture and uses the angular ceilings as reflectors, complemented with bespoke LED lighting that helps avoid glare. The architects were assisted by the proposed use on

the line of the existing compact, driverless rolling stock as used on other parts of the Copenhagen underground system. The use of such trains enabled a more compact and efficient approach to be taken in the design of stations, tunnelling, services and equipment.

HIDDEN SERVICES Another advantage of the modular kit-built approach to station design is the ability to use the cladding as removable access panels to service ducts containing existing facilities as well as accommodating future communication systems as technology moves on in the future. According to Anders Nøhr of Arup, the panelling

system met the architectural requirements, saying that they chose the ceramic panels because, when used on a large scale, they reveal a highly distinctive material and surface structure with a relatively low weight and are an extremely resilient, robust, vandal- proof and age-resistant cladding system. “Furthermore, the ceramic façade is a non-metallic

cladding that allowed us to install antenna cables for radio communication in the 150mm cavity behind the panels,” he says. Now that the Cityringen circle line is up and

running, it will be able to begin fulfilling the promise to help the city of Copenhagen to take a further step forward in its goal of being climate-neutral by 2025. Arup hopes to prove that the architecture of

railway systems can contribute greatly to a city’s identity, with a design that can be maintained, cost-effectively, long into the future. T&TH
