The operation of lines 16 and 17 of the Grand Paris Express will be awarded to Keolis. Lines 16 (from Saint-Denis-Pleyel to Noisy-Champs) and 17 will enter service from 2026 and 2028 respectively.

Keolis already employs 5,000 people in Île-de-France, where it operates buses in the outer suburbs and trams T9 and T13. The lucky winner will have the difficult task of running a long-awaited network, which will have swallowed at least 35 billion euros in 2030.
