The MF19 trains, built by Alstom, must enter service on line 10 at the end of 2025 at best. They represent an investment of nearly 5 billion euros between now and 2035.

In total, the 410MF19 trains will ultimately transport 40% of the metro network's passengers. The new trains will be deployed on lines 1, 2, 4, 5, 6, 9, 11 and 14, as well as lines 3, 3bis and 6, 7, 7bis.
