We have the knowledge, experience and high-spec equipment to provide a comprehensive range of services related to measuring, modelling and controlling railway noise and vibration.

Rolling noise

We regularly undertake measurements of wheel and rail roughness and track decay rates. These are used as inputs in our prediction model when conducting rolling noise investigations for clients. Our work on wheel and track dampers has led to huge advances towards quieter railways.

Source localisation

With support of an industrial partner, we have developed a large-scale 4m diameter array with nearly 100 microphones. This has been optimised for use near railways, and enables us to identify the specific areas of a train that are causing the most noise, thereby helping manufacturers to design quieter trains.

Prediction software

With our academic colleagues we have developed several in-house software packages that we can use to predict rolling noise, total pass-by noise, ground-borne noise and vibration from surface track and tunnels, plus structure-borne noise from raised structures such as bridges and viaducts.
