RATP has also awarded Alstom the contract to equip lines 7bis and 3bis of the Paris metro with this on-board technology.

Deployment Strategy and Timeline

The deployment on Line 10 is part of a broader strategy by RATP. Lines 5, 6, 9, and 11 are already equipped with the Octys solution developed by Alstom for RATP. The new trains will run on 8 lines of the Paris metro network, with Line 7bis following in 2026, Lines 3bis and Line 13 in 2027. From 2028, they will operate on Line 12, on Line 8 in 2029, Line 3 in 2031, and finally, Line 7 in 2033.

The MF19 metro train offers adaptability and modularity to suit the needs of eight Paris metro lines. It can be configured with 4 or 5 cars and measure between 61 and 77.5 meters, depending on platform length. It is available with automatic driving or a driver’s cab. On Line 10, MF19 trains are equipped in the “comfort” version, offering 146 seats and a total capacity of 586 passengers, rising to 828 during peak hours. This configuration also meets the needs of Lines 3 and 12. On other lines, the MF19 will operate in high-capacity versions providing 122 seats.
