Steel rails contribute to noise reduction in railways through several mechanisms. Firstly, steel is a dense and sturdy material that absorbs vibrations and reduces the transmission of noise. This helps to dampen the impact of passing trains, minimizing the noise produced. Additionally, steel rails are usually installed on a layer of resilient material, such as concrete or rubber pads, which further absorbs vibrations and reduces noise. Furthermore, the smooth and continuous surface of steel rails allows trains to travel with less friction, resulting in lower noise levels compared to other types of rail materials. Overall, the use of steel rails in railways plays a significant role in mitigating noise pollution and creating a quieter environment for nearby communities.
