The commissionning of metro line 14's northern extension

After several years of extraordinary works, the fully automated and underground Paris metro line 14 has been extended to Mairie de Saint-Ouen – Région Île-de- France in line with the aim to relieve congestion on metro line 13 by 25% and improve service quality for its 650,000 daily users. The works included a 5.8-km extension with four new stations built in a hyper-dense urban environment and the construction of a new train maintenance and storage depot. This involved major technological feats with three tunnel boring machines operating simultaneously, a new command station for the line, a new automatic control system, new trains and more, with delivery completed in the height of a pandemic.
