Creating an Intelligent Railway System: from big data collection to information distribution

Condition monitoring is the collection of big data from either rolling stock or railway infrastructure and can give valuable information for optimised management and maintenance of railway assets. Big data are usually characterised in terms of several Vs such as Value, Variability, Variety, Velocity, Veracity, Visualisation and Volume. These Vs are useful to understand how railways are already using or should be using condition data.

Big Data or Data at rest well describes the condition data used only once — just to check if safety parameters are met – and left to die in the so-called ‘data graveyards’.

The further use of condition data can reduce the number of system failures, missed or unnecessary maintenance activities by knowing current asset condition and their evolution to help mitigate risk at the minimum asset life cycle cost. In fact, today railways can take the big data from multiple condition monitoring devices and perform proper analysis not only to identify and to confirm safety related defects, but also estimate condition degradation and eventual future defects to recommend maintenance and renewal works. Moreover, the correlation of rolling stock and infrastructure data leads to an enhanced level of defects cause identification.

Other enterprise systems such as GIS, Dashboards for Asset Health Monitoring and Asset Management/Enterprise Resource Planning systems can integrate key information extracted from condition data. This allows for early identification of potential defects, accurate maintenance resources planning oriented to schedule and allocate workforce, machines, materials and possession time on the assets that need attention.

The increased decision-making capability potential requires railway companies to deploy a proper data collection and analytics strategy to integrate the disparate systems and the selection of a data analytics solution. Key objectives of such strategy should include:

Main user requirements to be covered to reach these objectives include the capability to:Establish a standard to exchange condition data between rolling stock and infrastructure managers or other contractors

The paper will illustrate and describe new practices and lessons learned originated from projects with several railways worldwide, where usage of significant amounts of data and information for condition based and predictive maintenance was the main concern.
