The project will involve lines 15, 16 and 17 covering more than 200km of new lines, 68 stations, depots and trains and will provide critical, high-speed 4G broadband wireless connectivity for both operational and maintenance needs, as well as emergency and security requirements.

This includes voice, data (file transfer and multimedia) and video services including transmission and onboard CCTV.

Engie Solutions will be responsible for studying, construction, and testing up to the commissioning of the system.
