Measures and Action

Banning the Blowing by Trains Running in Urban Areas of Beijing and Shanghai: Steady progresses were witnessed in preventing the railway noise. The Municipalities of Beijing and Shanghai banned the blowing by trains running in urban areas, which effectively improved the acoustic environment along the railways.
