Today’s urban rail transport networks are an essential instrument for large metropolitan areas in coping with the growing demand for punctual, reliable and environment-friendly transport services. Alstom’s solution to address that need is its Urbalis® communication-based train control system.
Resilience is the capacity to recover quickly from difficulties; in this context, it is the ability for the system to continue to perform its transport function, or to return quickly to nominal operation, after disturbances caused by unforeseen situations. The situations Urbalis® is designed to deal with are of three types: 1) hardware and software failures or degradations; 2) disruptions resulting from external perturbations, including passenger usage; 3) malevolent attacks.
To deal with hardware and software failures, Urbalis® relies on highly redundant architectures, in particular that of the data communication system which is its backbone, but also on the use of innovative maintenance and asset management strategies; in particular, predictive maintenance, supported by the HealthHub™ platform, aims at detecting degradations before they result in service-affecting failures.
