    This IRS was drawn up to provide all railways with standard guidelines to evaluate the causes of an incident involving the electrification systems and thus identify the relevant responsibilities.
    Until now, when an incident occurred, the search for the attribution of responsibilities was confined to the departments of a single company (infrastructure, rolling stock, driving staff). The new railway organisation, based on different operators, and their relevant respective roles means that an innovative approach is required to manage incidents involving both infrastructure and rolling stock.
    Thus the IRS focuses on the problems caused by failures within the energy system (substations, overhead contact line, pantographs, etc.), and classifies the responsibilities shared by the railway sectors/companies.
    The matter is also developed in conformity with the “Technical Specifications for Interoperability” (TSI), with the aim of defining the requirements to be fulfilled by Infrastructure Managers (IM) and Railway Undertakings (RU) to achieve the interoperability of rolling stock in different European countries, firstly for the high speed network and then for conventional lines. Even if the document conforms to the European Regulation, the content of this IRS is valid, applicable and approved at worldwide level.
    As a consequence, the document deals with the recording and analysis of failures affecting the OCL, both directly involving the contact line and produced by lack of energy in substations or power installations, under the direct or indirect responsibility of the IM.
    Special attention is required for the investigation of events involving rolling stock and the relevant RU, with a particular focus on OCL/pantograph incidents.

    To continue to pursue the objectives expected, the IMs have first to optimise the databases regarding the energy installations (location, performance, characteristics, maintenance done, previous failures, etc.) to input the investigation into all the subsequent analyses and considerations.
    If other companies are involved, such as RUs, IMs must accept their honest contribution to help clarify causes and responsibilities, on the basis of procedures and guidelines agreed.
    After defining causes and responsibilities for the incidents which have occurred, suitable statistics have to be input and updated to allow the different sectors/companies involved improve their organisational strategies and take effective countermeasures.
    This IRS is strictly linked with others prepared by the same UIC expert group and published by UIC on maintenance guidelines, diagnosis aspects and workers’ safety, including:
    IRS 70014 “Maintenance guidelines for overhead contact lines”, which defines the main parameters to be checked and observed and the maintenance activities to be carried out in order to ensure the expected OCL performance.
    IRS 70015 “Diagnosis of the OCL conditions” which provides information on the diagnostic systems in order to characterise the behaviour of the OCL in static or dynamic conditions.
    IRS 70016 “Safety measures to be adopted when working on or nearby overhead contact lines” which provides guidelines for improving the safety of personnel working on or in the vicinity of OCLs.
    This IRS sets out guidelines which can be applied to railway energy systems fed both by DC and AC current, under different traffic conditions, speeds, etc.
    IRS 70017 can be applied to energy systems operating at the following voltages:
    1.5 kV and 3 kV DC;
    15 kV – 16 2/3 Hz;
    25 kV – 50 Hz. This IRS was drawn up to provide all railways with standard guidelines to evaluate the causes of an incident involving the electrification systems and thus identify the relevant responsibilities.
