Railways are an environmentally friendly means of transport well suited to modern society. However, noise and vibration are key obstacles to further development of the railway networks for high-speed intercity traffic, for freight and for suburban metros and light-rail. All too often noise problems are dealt with inefficiently due to lack of understanding of the problem.
This book brings together coverage of the theory of railway noise and vibration with practical applications of noise control technology at source to solve noise and vibration problems from railways. Each source of noise and vibration is described in a systematic way: rolling noise, curve squeal, bridge noise, aerodynamic noise, ground vibration and ground-borne noise, and vehicle interior noise.
Theoretical modelling approaches are introduced for each source in a tutorial fashion
Practical applications of noise control technology are presented using the theoretical models
Extensive examples of application to noise reduction techniques are included
Railway Noise and Vibration is a hard-working reference and will be invaluable to all who have to deal with noise and vibration from railways, whether working in the industry or in consultancy or academic research.
David Thompson is Professor of Railway Noise and Vibration at the Institute of Sound and Vibration Research, University of Southampton. He has worked in the field of railway noise since 1980, with British Rail Research in Derby, UK, and TNO Institute of Applied Physics in the Netherlands before moving to Southampton in 1996. He was responsible for developing the TWINS software for predicting rolling noise.
* Discusses fully the theoretical background and practical workings of railway noise
* Includes the latest research findings, brought together in one place
* Forms an extended case study in the application of noise control techniques

Introduction
1.1 THE NEED FOR NOISE AND VIBRATION CONTROL IN RAILWAYS
To some of us the sound of a passing train is music to the ears. Audio recordings of trains are sold; the sound of a steam engine labouring up a gradient or passing at speed may evoke a strong impression of its power or the nostalgia of a lost age. But to many people the noise from passing trains is unwanted and can be considered a disturbance.
It has always been so. The early railways were often subject to considerable opposition. The following was written in 1825, in a letter to the Leeds Intelligencer (quoted in [1.1]): 'Now judge, my friend, of my mortification, whilst I am sitting comfortably at breakfast with my family, enjoying the purity of the summer air, in a moment my dwelling ... is filled with dense smoke, .... Nothing is heard but the clanking iron, the blasphemous song, or the appalling curses of the directors of these infernal machines.' Nevertheless, although some objections such as this were attributed to environmental reasons including noise, most were based on economic or aesthetic arguments. An interesting example occurred as early as 1863, when the Manchester, Buxton, Matlock and Midlands Junction Railway (later to become part of the Midland Railway) in England was forced to build its line in a shallow cut-and-cover tunnel almost 1 km long so that it should not be visible from the Duke of Rutland's home at Haddon Hall. Today such schemes and changes in alignment are not uncommon to mitigate noise, but the idea is clearly not new.
Particularly since the 1960s, environmental noise has become an increasingly i
