Predictive Maintenance in Railways

Maintenance in Railways is a key economic stake, while contracts increasingly include demanding availability and reliability targets. This situation drives the development and deployment of predictive maintenance: by spotting degradations before they result in service-affecting failures, the latter can be avoided while reducing maintenance costs.

The“Prognostics & Health Management” ( PHM) discipline has emerged since the turn of the century, first in aerospace , defense and nuclear applications, and then in other fields such as railways. It is the discipline of developing methods and tools for predictive maintenance and for related decision support.
