Last update: Sustainability Report 2018

In investing substantial resources for projects to maintain and improve the existing network (new technologies for train traffic, electrification, double tracks, upgrading, redevelopment of stations, maintenance, etc.) and for new railway infrastructures (new lines and new systems for passenger and freight traffic, including intermodal solutions), as well as the purchase of new rolling stock in line with the most recent technical specifications, the Group is constantly committed to mitigating noise at source, at sites, railway yards and stations, as well as installing permanent fixtures to reduce the noise of railway operations and in experimenting with devices to be applied to the superstructure to reduce the noise generated by train/track contact.

The following are the most common solutions that can be used to mitigate noise pollution generated by fixed plants and sites:

  • enclosing the noisiest machinery;
  • acoustic screens (noise dampening barriers or enclosures with noise dampening treatment);
  • scaling of shifts when the noisiest machinery operates and its use during the day.
