Dr. Daniel L. Cadet

Cadet Railway Consulting

Former Director for External Technical Affairs R&D and Innovation ALSTOM Transport,
France

Short biography :

Education in Physics and Fluid Dynamics, PhD in Physics in 1980 at Ecole Polytechnique. He was Junior researcher at CNRS (Weather and Climate) from 1974 to 1980. He became a Professor at Florida State University US from 1980 to 1985, teaching meteorology. He was a senior researcher at CNRS from 1985 to 1990, before becoming Deputy-Director of the CNRS “Sciences of the Universe” Department, in charge of Ocean & Atmosphere labs and national equipment from 1990 to 1995. From 1996 to 2000, he was Director of the CNRS International Affairs Directorate, initiating a program of creation of International Labs between CNRS and partner institutes in different countries. In 2001, he quit the public sector to move to ALSTOM to become the Director for External Technical Affairs, covering all world, at ALSTOM Transport Headquarters where he stayed till he retired in April 2016. Consultant since that date.

Dr. D. L. Cadet has participated to the preparation of a large number of National and European Projects (more than 50) giving him a comprehensive expertise on the railway sector. He was “scouting” the world for innovation that could benefit the railway industry. He developed strong links between ALSTOM and Academia throughout the world. He was the ALSTOM representative in the team that established the SHIFT2RAIL Joint Undertaking, a jointly 920M€ funded Railway Research Program by the European Commission and the Industry under H2020.

 Title : "Intelligent Textiles and Composites in Railway"

Railway is recognized as the mean of transport with a minimum impact on the environment and less fatal accidents than other modes and able to answer to the increasing demand for the transport of persons and goods. Large investments are made throughout the world to offer rail services for long distance, regional, urban and suburban. The specificity, with the recent evolution, of rail transport industry (manufacturing, operators and infrastructure managers) will be presented. Due to the increasing competition between the main global railway integrators and the paramount importance to reduce rail operating costs, innovation is seen as a major differentiator for a modal shift from road to rail. Constraints due to the railway culture and safety, is hampering the rapid introduction of innovation. Examples of latest innovations will be presented.

Composites have been used for a certain time in the construction of train coaches but essentially for interior fittings with recent activities to use more bio-sourced materials. Intelligent materials are foreseen to make rail travel more attractive. The use of composite materials for structural parts of carbodyshell or bogies have been explored during more than 10 years but without being introduced for commercial operations of trains. One main issue is to meet the drastic railway norms which are explicitly refering to metallic materials, to obtain homologation/certification for commercial operations. Examples of recent projects will be given. Monitoring (Prognostic Health Maintenance) of structural parts using composite materials is also a key issue as a coach is operating for at least 35 years and must satisfy the highest level of safety. Whereas the railway industry is not keen at using too many sensors on-board a train, some work is being done and will be presented.
