Trials and blank runs:
Tests are carried out to check the adequacy between the infrastructures and the metro. Simulations without passengers, called blank runs, are then carried out to check the proper functioning of the equipment in real conditions.Release:03 Release Date:03/12/2022


Commissioning:
