At the end of 2010, it was revealed that ten stations would receive platform screen door installation in an attempt to increase the average speed of trains and reduce track-related incidents. After a test a few years earlier, the RATP decided that such doors must be built as crowding increases so that passengers cannot fall off the platform; to do this, the agency recruited the Kaba Group to perform automation and installation on Lines 1 and 13. The company uses the ClearSy security system to control door opening and closing. However, the new platform screen doors are not the same as the prototypes installed at Invalides.
