A small crowd waited on the platform at Porte d'Auteuil station for the arrival of the brand-new MF19 on the morning of Thursday, October 16. In notable silence, the train – which to the untrained eye resembles those belonging to Lines 11 or 14 – opened its doors to Valérie Pécresse, president of Ile-de-France Mobilités (IDFM, the Paris region's transport authority), and Jean Castex, head of the Paris public transport operator (RATP) who will soon depart for the French National Railways (SNCF), for a ceremonial first ride.

One notable fact: The first MF19 train, built by Alstom, has entered service two weeks ahead of schedule, marking the culmination of more than five years of major work that will allow half of the Paris metro fleet to be renewed by 2033. The cost is enormous: €3 billion for rolling stock and €4 billion for infrastructure and maintenance centers, all funded by IDFM.

Although the average age of a train set is generally 40 years, this model, described as "cutting-edge," replaces units that are over 50 years old. Its many features include ergonomic seating, real-time information displayed on screens and cooled ventilation. The new train is quieter, more spacious, more energy-efficient and designed to be accessible for people with reduced mobility.
