The northern extension of line 14 should open in mid-December - Mario FOURMY / SIPA

Originally, it should have seen the light of day in 2017. The coronavirus crisis has once again postponed the entry into force of the northern extension of line 14. In a press release published on Thursday, the RATP indicates that three new stations - Pont-Cardinet, Clichy-Saint-Ouen and Mairie de Saint-Ouen - will be inaugurated in mid-December. The last one, Porte de Clichy, will be usable from January 2021. A delay which can be explained in particular by the fact that this station, more extensive than the others, requires more work.

[# ProlongementNordLigne14] Impact of the health crisis: #RATP plans to commission the northern extension # ligne14 for mid-December 2020 with the opening of 3 stations (Pont Cardinet, St-Ouen, Mairie de St-Ouen) and the opening of Porte de Clichy in January 2021. ⤵️

Originally, the commissioning of this part of the line was planned for the summer of 2020, but the confinement greatly slowed down the progress of the works. The RATP nevertheless maintained traffic tests between the Madeleine and Porte de Clichy stations or work on electromechanical equipment in stations, such as installing escalators or elevators.

The purpose of this extension is in particular to relieve congestion on line 13. According to various studies, 25% of travelers could refer to it. In order not to saturate the new line, the RATP plans to enlarge the trains. From September, "subject to the successful completion of final tests", the trains on line 14 will consist of eight cars instead of six.
