What does "noise abatement" refer to in railway systems?

Noise abatement in railway systems specifically addresses the measures taken to reduce noise pollution, particularly in urban areas where train operations may significantly impact the surrounding community. This involves implementing sound barriers, modifying train components, and adopting practices that lower the noise generated during train operations, such as quieter wheels and improved track design.

The focus on mitigating noise pollution is crucial in promoting a more harmonious coexistence between railway operations and residential or commercial areas. By reducing noise, railways can lessen disturbances for nearby residents, leading to better public relations and compliance with local noise regulations.

While improving engine performance, enhancing passenger comfort, and ensuring environmental compliance are important aspects of railway operations, they do not specifically relate to the primary goal of noise abatement, which centers on decreasing noise levels caused by train operations.
