Hitachi Rail USA is supporting the modernisation of the Washington Metro with the new 8000 series trains, designed to meet the highest standards of safety, availability and performance. These new trains will need to interface with the safety system that controls the opening and closing of platform screen door monitoring systems.
Before a train can depart, it is essential to ensure that the platform screen door monitoring systems are fully closed and locked. This safety function requires tried-and-tested components capable of ensuring maximum reliability throughout the system’s lifetime.
It is in this type of application that CLEARSY’s RS4 safety relays demonstrate their value. Already deployed in numerous automatic platform door systems, they enable the ‘doors closed and locked’ signal to be transmitted securely and contribute, every day, to passenger safety on the most demanding metro networks.
