Cityringen Metro, Copenhagen

Cityringen: a metro system for a carbon neutral future

Copenhagen is one of the most densely populated areas of Denmark. The new circular metro extension, Cityringen, expands the city’s existing system, and is a key part of its drive to become carbon neutral by 2025. Metroselskabet, Copenhagen’s transit authority, appointed Arup in joint venture with Cowi and Systra to act as the multi-disciplinary technical advisor for this ambitious design and build project, the city’s largest construction project in more than 400 years. 

The new line seeks to encourage more residents out of their car and onto a more environmentally-friendly mass transit network. Now that more than 16 kilometres of twin-bore tunnels and 17 new stations have been completed, Cityringen ensures that a majority of Copenhagen’s residents will be within 600 metres of a train or metro station. 

Arup led the architectural design, taking a user-centric ethos at every step of the way. Our intuitive-minimalism, inspired by the Scandinavian design tradition, has led to spacious, light-filled stations with distinctive internal façades that echo the local spirit of the areas they connect to. 

Project Summary

17 new stations

16 kmtwin bore tunnel

-- year project


Arup led the architectural design team on Cityringen and designed most of the fixtures within the 17 new stations. The firm’s biggest challenge was to develop a state-of-the-art solution for a project that has already won a clutch of international awards.

Arup’s specialists are creating a desirable experience for the passengers who will travel on Cityringen when it is completed in 2019. The goal is to create spaces that meet the intuitive and natural demands of the travellers and to provide them with positive and memorable travel.

A train station is much more than just a platform, getting a train from A to B. Cityringen stations are all about meetings and departures, expectations of the known and the unknown, light and reflections, shadow and brightness. The architecture and design will be simple, easy to understand and capable of incorporating all technical solutions in a human and straightforward way.
