Alstom publishes environmental declaration for its new generation of beacons

03/01/2017

Alstom has published the environmental declaration for its new generation of beacons. SmartBalise is an ecodesigned product, with minimised environmental impact all the way from manufacture to end-of-life. Its environmental performance is presented in the declaration, available for consultation today on the PEP Ecopassport® website in compliance with the requirements of ISO 14025.

The beacons - those yellow boxes located along the tracks - allow the train to retrieve signalling and safety data sent by the control centre with the help of an encoder, which acquires data related to the status of the signalling. The SmartBalise revolutionises the traditional concepts of the signalling market by integrating the encoder function within a conventional beacon. This "2-in-1" approach leads to significant environmental gains.

By comparing 4 SmartBalises used over a period of 20 years with 4 previous-generation balises linked up to a data management module, the results obtained over the life cycle of the beacon are remarkable: a 75% reduction of energy obtained from fossil-fuel sources, an 86% reduction in energy consumption, corresponding to the annual consumption of a 400 m² low-consumption building, and an 81% reduction in water pollution, corresponding to the consumption, all uses combined, of 4000 people over a whole year.

With more than 100 experts in ecodesign, energy and materials, we are continuously optimising the environmental performance of our solutions and promoting the image of rail, which remains the most sustainable mode of motorised transport,” said Véronique Andries, Director of Ecodesign at Alstom.

Because electrical and electronic equipment represents 11% of the mass of a train but 40% of its manufacturing impact, Alstom engineers have also adopted ecodesign in the development of electronic products in order to significantly reduce the company’s environmental footprint.

This approach was rewarded in 2014 with the extension of the ISO 14001 site certification to product design and a maturity level of 3 out of 4 obtained under the AFAQ ecodesign evaluation model. Alstom’s Villeurbanne site thus became the first certified company in Rhône-Alpes to receive two-fold recognition for this expertise.

In addition to the SmartBalise, significant results in ecodesign have been obtained for Alstom's electronic products, such as the improved environmental performance of a signalling bay with increased computing power (leading to a 42% reduction in energy consumption) or a 54% reduction in the energy consumption of the on-board computer for urban signalling.
