In the framework of the S2R Innovation Programme 3 (IP3) “Cost efficient and reliable infrastructure”, of the S2R Master Plan, there are, inter alia, two Technological Demonstrators (TDs) in the S2R MAAP aiming at generating knowledge from data:
“Smart Metering for Railway Distributed Energy Resource Management System” (TD3.10), where the specific challenge relies on the technology development and demonstrator implementation in order to realise:
o A non-intrusive Smart Metering sensor networks at Railway System level.
o An open system and interface for data collection, aggregation and analysis in an open source Operational Data Management (ODM) Platform.
o A set of User Applications design and specifications. The Applications will exploit the energy analysis process with the aim of enhancing the energy decision making and the line operation patterns, as well as other possible improvements such as preventive maintenance.
“Dynamic Railway Information Management System (DRIMS)” (TD3.6) where the challenge is to generate knowledge from data and/or information – driven whenever necessary by the available domain knowledge - valid for life cycle management and intelligent asset maintenance planning including automatic detection of anomalies, discovering and describing the maintenance workflow processes and implement predictive models of decaying infrastructural assets.
The proposed research and innovation activities should address both work streams described below, in line with the Shift2Rail Multi-Annual Action plan (MAAP):
• Work-stream 1: Management of energy related data
The activities regarding this work stream should cover all following elements:

Energy profile prevision improvement. Refined knowledge of the traffic disturbances and consequences on system’s energy profiles.
Continuous supervision of power supply equipment status. Improved reliability and LCC based on predictive maintenance by continuous supervision of energy consumption and early identification of the abnormal variations.
Optimized return of investment (ROI) and ability for developing a better business plan, allowing optimal investments and asset management.
Better identification of electric infrastructure losses.
Better identification of auxiliary, maintenance facilities and stations energy consumption and of opportunities for savings and for demand-response.
Increasing the power supply quality and optimizing the line capacity.
Better coordination between the energy hourly variation prices and the traffic operation.

A significant impact is expected from the methodologies and tools for business security, economic sustainability and decision support in the field of big data and analytics railway applications on the following areas: 81
Improvement of capacity – a large improvement in line capacity due to a more effective asset maintenance management;
Improved Reliability: failure modes of current systems will be reduced/eliminated due to the new “intelligent asset management”;
Improved safety – as a consequence of the improved reliability, the number and magnitude of incidents will be reduced;
Significant LCC savings should be possible, due to new asset management approach.
Specific metrics and methods to measure and achieve impacts should be included in the proposals, with the objective to achieve by the end of the S2R Programme the quantitative and qualitative targets defined in the S2R MAAP related to TD3.6 and TD3.10 in line with the relative Planning and Budget.
