4th Harmotrack Project Plenary Meeting


Thursday 2nd December 2021 (CET) + Room 203, UIC Headquarters / Online

Introduction

Connecting the world to define the future international technical specifications on the use of dynamic measurements.

The UIC Harmotrack Project brings together more than 200 international railway experts from more than 70 railway companies and academic institutions all across the globe. Led by SNCF Réseau, the Harmotrack Project aims to:

  • Provide an international benchmark to carry out a State of the Art of measurement techniques for dynamic responses (acceleration and forces) to monitor the track quality;
  • Define the domain of use for the acceleration measurements and best devices specifications;
  • Define reliable indicators or track quality (increased vigilance, interventions, or slowdowns) based on accelerations for an improved network maintenance and simulation purpose;
  • Contribute to enhance safety and reduce costs on all networks by prioritising corrections of track geometry defects focusing on those with the most dangerous impact on vehicle dynamics;
  • Propose a future international standards or technical recommendations on the use of dynamic measurements.

The plenary meeting will highlight a roundtable discussion with Directors/CEOs from different railway companies and institutions all across the globe. The roundtable discussion will be open to the public and the high-level speakers will exchange about the following topics.

  • Roundtable 1: Railway maintenance and predictive maintenance moderated by David Briginshaw (International Railway Journal) with Marco Gallini (RFI), Atsushi Furukawa (RTRI) Albert Wahba (National Research Council Canada)
    • Today railway maintenance plays a key role in maintaining a high level of performance our railway systems. New technologies arose during the last year that could radically change how we consider railway assets.
  • Roundtable 2: Importance of railway digitalisation and data analysis of autonomous systems moderated by Christian Chavanel (UIC) with Emmanuel Cox (SNCF Réseau), Sébastien Denis (Shift2Rail), Gerald Schinagl (ÖBB)
    • Digitalisation in railway sector introduced many changes that are perceived by stakeholders as an opportunity but also as a challenge.
  • Roundtable 3: Harmonisation of global practices: the key to foster railway sector development moderated by Philippa Dean (Railways Africa Magazine) with Patrizia Gatti Gregori (KEOLIS), Andrea Giuricin (TRA consulting), Eneida Elezi (Albanian Railways S.A. and Ministry of Infrastructure and Energy)
    • The harmonisation of global practices and the definition of new standards facilitate the information sharing between railway companies.

This year’s plenary meeting will also feature the advances by the sub-working groups in the project.

  • SWG1: Determination of Thresholds for Accelerations:
    • SWG1-A to study the correlation between measured forces and accelerations;
    • SGW1-B to study the correlation between measured track geometry defects and accelerations:
      • SWG1-B Alpha to study filters applied to dynamic measurements;
      • SWG1-B Beta to study the correlation between track geometry and accelerations, with the intent to both detect exceedances and qualify geometric defects using acceleration signals (maintenance oriented):
        • SWG1-B Beta 1 to study the most dangerous combinations of track geometry defects using multi-body simulations;
        • SWG1-B Beta 2 to study the correlation between track geometry and accelerations using statistical analysis;
        • SWG1-B Beta 3 to study the detection of track geometry defects using machine learning techniques.
    • SWG1-B Gamma to study threshold occurrences and to use risk analysis approaches to transfer thresholds from a reference vehicle to a different one while taking into account possible various speeds.
  • SWG2: Optimal use of AxleBox Accelerations (ABA) for the detection of short length track defects;
  • SWG3: Use of innovative and cheap devices to monitor the track quality.

Please note that the afternoon session is exclusive for Harmotrack members only.

Furthermore, parallel technical visits are organised at SNCF facilities on the second day (3rd December 2021). The technical visits will be open to the public. However, due to health restrictions, limited slots are available and priorities will be given to the Harmotrack Project members.

The technical visits include:

  • SNCF Réseau - Centre d’Essais Voie (CEV) - Track Test Center
    • Located in the inner suburbs of Paris at Saint-Ouen, CEV specialises in tests on track components (sleepers, fastening systems, under-sleeper pads and under-ballast mats). The laboratory, reports to the Track and Surroundings department of SNCF Réseau and has honed its international experience and unprecedented knowledge of the ballasted and ballastless track sector since 1946.
  • SNCF Voyageurs - Agence d’Essai Ferroviaire (AEF) - Railway Test Agency
    • The Railway Test Agency (SNCF – AEF) is located close to Paris and extends over 3.75 hectares at Vitry sur Seine. Scientific and technical skills required to perform tests or expert appraisals on rolling stock can be found here. The laboratory started in 1933 with the inauguration of the “locomotive test rig” and then became the Vitry test centre and, subsequently, AEF in 1999. The Railway Test Agency holds ISO 9001, ISO 14001 and OHSAS 18001 certification and is accredited under ISO 17025 on multiple tests.
  • SNCF Réseau – Laboratoire d’Expertises Métallurgiques (LEM) – Metallurgic Expert Assessments Laboratory
    • Also located in the inner suburbs of Paris at Saint-Ouen, the LEM specializes in tests and expert assessments on metallurgical components of tracks, in particular on rail and its welding processes. The laboratory also analyses every broken rail on the French National Network. The laboratory reports to the to the Track and Surroundings department of SNCF Réseau, and was created in 1938 following the merge of laboratories of the former regional railway companies.

Centre d’Essais Voie (CEV) - Track Test Center and Laboratoire d’Expertises Métallurgiques (LEM) technical visits will be done over the same morning session.
