How do railways handle train noise pollution?

Train noise pollution is a major concern for both the railways and the communities located near the tracks. To mitigate this issue, railways use various measures to reduce the noise generated by trains. Some of these measures include:

• Track maintenance: Regular maintenance of tracks can help reduce noise generated by trains. This includes using continuously welded rail, which reduces the clicking sound made by the wheels, and grinding the rails to reduce noise.
• Noise barriers: Railways can erect noise barriers along the tracks to reduce the noise levels in nearby communities. These barriers can be made of different materials such as concrete, steel, and wood.
• Quieter technology: Railways are constantly developing and implementing quieter technologies for trains, such as noise-reducing wheels, quieter engines, and noise-absorbing materials in train cars.

Some railway companies also have noise reduction programs in place to address noise pollution. These programs may involve working with communities to identify problem areas, implementing noise-reducing technologies, and monitoring noise levels to ensure compliance with regulations.
