Here is the Paris metro of the future
This page is translated from the original post "Voici le métro parisien du futur" in French.

The future Line 15 subway has completed its first test runs today. Its development begins ahead of an opening scheduled for late 2025.
The future Line 15 subway is entering a new phase before its official opening. The first wheel turn of a train took place on Tuesday, November 28, 2023, in Champigny-sur-Marne, in Val-de-Marne. An event that heralds the start of dynamic testing, which will begin in summer 2024.
During dynamic tests, the performance of the future Line 15 metro trains is tested under operating conditions on lines closed and reserved for testing. Braking, acceleration, safety, comfort — everything will be thoroughly examined.


The future Line 15 is divided into 3 sections that will be gradually put into service:
- By late 2025 for the southern section connecting Pont de Sèvres to Noisy Champ
- By 2030 for the eastern section linking Champigny Centre and Saint-Denis Pleyel, and the western section connecting Pont de Sèvres and Saint-Denis Pleyel stations.
Forming a 75 km ring around Paris, connected to the rest of the network by numerous connections in four departments, the various sections of the future Line 15 will drastically reduce daily travel times across Petite and Grande Couronne, eliminating the need for transfers in Paris to travel between suburbs.
