# 1/7 Cityringen: Railway track construction for Copenhagen's new “Cityringen” metro. GCF Copenhagen Site Manager Francesco Costa Medich illustrates the progress of railway track construction for Copenhagen Metro's new M3 line, known as “Cityringen” because of its ring shape. The project, a leading European example of bicycle-friendly urban intermodality, will contribute to making Copenhagen the world's first “carbon-neutral” capital.
