The STM has implemented three programs for asset maintenance and development of the metro network. The Réno-Systèmes program’s objective is to replace and refurbish the metro’s fixed equipment that has reached or exceeded its lifecycle. The Réno-Infrastructures program was set up to intervene preventively on all infrastructures. The Metro Accessibility program is directly devoted to the development of the level of service and improving the custom.er experience in terms of universal accessibility by integrating elevators into stations that already exist and are in operation, as well as the integration of new pieces of art in those stations.
