Several lines on the Paris Metro are fully driverless and automated (Grade of Automation 4), and this network is expanding rapidly. As of 2026, Lines 1, 4, and 14 are completely automated, meaning there is no driver's cab and passengers can sit at the very front for a "windshield" view of the tunnels. Line 14 was recently extended to Orly Airport, making it the longest automated line in the city. Additionally, the massive Grand Paris Express project is rolling out several new driverless lines, including Lines 15, 16, 17, and 18, which are scheduled to open in stages starting in late 2025 and 2026. These new trains are operated by remote control centers and use advanced signaling to run as frequently as every 85 seconds during peak times. While older lines like Line 9 or 13 still use manual drivers, the RATP is in the long-term process of retrofitting more of the network for automation to improve reliability and reduce energy consumption. By 2026, the "automatic" metro has become the backbone of the city's modern transit identity.
