Rail Dampers, Acoustic Rail Grinding, Low Height Noise ,High-speed rail grinding and metal removal

5 2 Introduction and aim of study There are many noise mitigation options open to railways Some of them - such as noise barriers - have a known effect and are used widely, others such rail dampers, acoustic rail grinding or lowThis ability to grind rail at increased speeds has been accomplished through the introduction of a new generation of sophisticated control systems together with specially-designed high-speed buggi This increase in grinding speed has been quite dramatic, going from the four to eight mph grinders of the s to the modern 10 to 14-plus mph.
