Pass-by noise assessment of high speed units by means of acoustic measurements in a perimeter close to the train
Characterization of rolling stock from the perspective of exterior noise emission is typically carried out by following the technical procedures detailed in the international standard ISO 3095. Whilst this standard can be considered adequate for conventional rolling stock, the advent of very high speed railway transport has introduced a number of challenges in terms of…

A simplified model for calculating the insertion gain of track support systems using the finite difference method
In the procurement of track support systems for railways planned in the vicinity of receptors sensitive to groundborne noise and vibration it can be necessary to specify parameters of components of the system in order to ensure that its in-service performance will deliver the required level of mitigation against the effects of groundborne noise and…

Integrated design development of the Colne Valley Viaduct
The Colne Valley Viaduct, a 3.4km structure, will be the longest railway viaduct in the UK and has been designed to meet demanding technical, environmental and operational requirements. A key challenge for the multi-disciplinary integrated team has been to balance these requirements with the needs and aspirations of the client and local community stakeholders for…

Predicting sound levels generated by jet fan ventilation systems in tunnels
The operation of jet fans to ventilate tunnels generates sound that propagates within the tunnels, and can be emitted to external locations, which may include noise-sensitive receptors. To achieve suitable predictions of noise impact, it is important to account for the propagation of sound inside tunnels, which is an engineering problem not addressed by current…
