Cristina Vaz Tomé, CEO of Metropolitano de Lisboa, announced that the new CBTC signaling system, set to launch with the new circular line next year, will eventually enable driverless train operations. While the system is already being tested for safety, full automation requires further investment, political consensus, and infrastructure upgrades, such as platform screen doors. Tomé emphasized that staff will be retrained for new roles as the network evolves.
