It is widely recognised and well documented that one of the top two infrastructure causes of train delay in the UK rail network is the ubiquitous 'points failure'. Network Rail has established that on a national basis the average failure rates of existing electro-hydraulic and electro-mechanical points machines are 0.85 years and 1.3 years per point-end respectively.
The high-performance switch system (HPSS) is a solution to such problems. It is a technically advanced, fully integrated system, offering major advances in switch actuation technology and is designed to provide exceptional operational performance in terms of reliability, availability, maintainability and safety (RAMS). It comprises all elements of actuation, lock and detection of the switch rails.
It is made up of a high-performance switch actuator (HPSA) - a robust electro-mechanical in-sleeper points machine, with built-in condition monitoring - and a
‘PowerLink’ (torsional) backdrive, a supplementary drive system mounted in the four-foot, with in-sleeper stretcher bars and supplementary detectors.
