An agenda of product evolution

Rail traffic is expected to increase by 5% per year over the next ten years, driven by increasing urbanisation and the rise of environmental concerns.  The rail industry is a buoyant market that is striving to upgrade its products in order to meet the industry’s new challenges.

Towards the development of products to meet market needs

Tramway, TGV, metros… These modes of transport afford greater user mobility and a better quality of life in general. The main challenge for cities is to modernise their transport systems in order to make them more efficient and environmentally friendly, promoting the aesthetic side of cities, freeing up public space and improving quality of life in general.

Sector stakeholders (equipment manufacturers, building contractors and operators) are working together to improve potential solutions to the following issues:

  • Developing quieter and less polluting equipment;
  • Increasing transport capacity;
  • Making vehicles lighter (locomotives, carriages and wagons) and implementing new engines (including hybrids…), alternative fuels;
  • Reducing the consumption of on-board devices (e.g. heating, cooling and ventilation equipment) and managing the materials used in design and maintenance;
  • Allowing rapid modification of the interior environment while providing the expected level of comfort;
  • Improving safety and developing automation.

Addressing such issues as rail equipment, which require high levels of technical skills and increased investment in research and development in order to remain at the forefront of technology.
