GOING AT THE SOURCE OF A PROBLEM

Our Commitment to Environment and People

Trains are among the most sustainable (green) forms of transport, yet noise pollution is a serious problem to address.

According to the World Health Organisation (WHO), traffic noise alone is harmful to the health of almost every third person in the WHO European Region.

 

So far just 33% of wagons are Noise TSI compliant.

The vibration of the wheel starts from 1600 Hz.
The main source of noise pollution of the train happens at the frequency of 2000 – 4000 Hz and can reach 8000 Hz.

OUR SOLUTIONS

The widest line of noise cancelling solutions

Lucchini RS has started to work on the noise pollution issue long before the market has requested it, which allowed the group to develop the widest range of noise cancelling solutions for the train wheels. We’re proud to have reduced total vehicle noise emissions for more than 6dB on thousands of vehicles.

PRODUCTS

Lucchini RS Group has developed a number of solutions reducing noise caused by railway wheel operations.
A significant reduction of the vibration (and thus also noise) of wheels in operation is achieved through the combination of SYOPE technology and STARDAMP (TWINS algorithm based software)

SILENCE-DRIVEN DESIGN

We start optimizing the overall emissions of our wheels during the DESIGN phase by using the STARDAMP software, impacting the noise reduction AT SOURCE.

STARDAMP software analyzes the wheel geometry, the roughness conditions of the wheel/rail interferences and allows to scientifically quantify the efficiency of acoustic rail and wheel dampers, thus, reducing the need for costly field tests on real track.

Software used to validate lower noise emissions of our SURA(R) wheels.

SILENCE THE NOISE

REDUCE TOTAL ROLLING NOISE

The radial wheel-sound absorbers, especially effective at high speeds are proven to reduce the rolling noise by up to 9 dB(A) on the total noise emission of the vehicle.

ELIMINATE CURVE SQUEAL

Reduce the disturbing curve travel noise with our axial sound absorber by up to 41 dB(A) at specific squealing frequencies.

WHY SYOPE?

Getting to the Core of SYOPE

Syope means “silent” in Ancient greek and it has been considered a virtue by many philosophers.

Socrates has believed that silence is not an absence of noise.

It’s a profound melody that can be heard about all the noise. When the volume of the train wheels’ is turned down it becomes a “white noise”, that can promote relaxation, lower stress levels and improve sleep.

We invite you to experience the core of “Syope” with the relaxing Train Sounds.

Listen to the lulling sounds of the night train riding through the scenic Italian countryside or let the stress flow away while soft rain falls on the roof and thunder breaks the beautiful monotony of the train wheels humdrum.

 

The quieter you become the more you can hear.

Trains

Excessive noise may be caused by a problem with a specific train or track. We own and manage the rail network but we don’t run trains, so while we’ll do everything we can to give you advice and help investigate train movements, we usually have to work with the train company and local authority, which means we can’t take any specific action to resolve the problem.
