Completion of the transition of the Line 4 fleet of 52 trains to driverless operation was announced on January 19, 2024.
Running for 13.9 km from Porte de Clignancourt to Bagneux-Lucie Aubrac, Line 4 is the second-busiest line on the Paris metro, carrying 700,000 passengers a day.
Conversion to automatic operation has cost €480m, met entirely by regional transport authority Île-de-France Mobility. Work on the project began in 2016 and has been undertaken without major closures.
RATP highlights the increase in line capacity, the ability to adapt the train service to meet demand in real time, and the reduction in headways between services from 105 to 85 seconds.

All in all sounds rather impressive....
BTW, the busiest line in #1, fully automated since 15 December 2012.
