The stations at São Paulo Metro lines 5 and 17 are upgraded with platform screen doors. This will prevent passengers from unintentionally falling into the track area or, in the case of monorail systems, into depth. There are functional safety requirements for the communication between the train and the platform screen doors. Safety needs to be proven according to the European standard for RAMS.

Our company supervises this process. Furthermore, we advise operators and system suppliers and we also conduct the risk and safety analysis. The resulting SIL 3 selection is verified by our independent experts.

Finally, the generated, verified and validated documents are examined according to EN 50126 and a certificate is prepared.
