Passenger safety begins with the design of the stations and the materials used in their construction: reinforced concrete, stainless steel and tempered glass.
Throughout the entire line, security guards monitor trains and stations and help people who require aid.
Concerning the stations and their conditions of safety and renewal, we must mention that all underground stations have double accesses, which guarantees, with this layout and based on trials that have been performed, that the platforms, even when crowded, can be evacuated in four minutes and the entire station in about ten minutes.
A two-way intercom system enables commuters to contact the stationmaster for assistance or the Operations Control Centre in his absence.
