SNCF trial to tackle brake dust emissions

Technology designed to suck up the particles emitted by trains during braking is to be trialled by SNCF.

Working with Tallano Technologie, SNCF will fit the TAMIC® system to trains in the Ile-de-France region as part of an experiment which aims to improve air quality at stations.

SNCF believes the trial, which is financed by the Ile-de-France region, will run for two and a half years and is the first of its kind in the world.

A small turbine will be installed next to the brake disc which activates during braking and sucks particles from grooves within the brake pad.

As well as its applications in rail, Tallano Technologie has developed a similar solution for the automotive sector.

According to SNCF, the particles produced during braking are a significant pollutant in underground stations.

Although less than 7 per cent of the 391 stations operated by SNCF Transilien in the Ile-de-France region are located underground, SNCF said it felt it was still important to find a solution.
