There are several factors that contribute to noise reduction in railway tracks thanks to steel rails.
Firstly, the smooth surface of steel rails helps to reduce friction between the train wheels and the track. This smooth contact significantly decreases the noise generated. In contrast, if the tracks were made of materials such as wood or concrete, the rough surface would cause more friction, leading to increased noise.
Secondly, the high density and stiffness of steel rails aid in dampening the vibrations caused by the moving train. These vibrations can create noise that spreads through the air and the ground. The high density of steel absorbs and disperses the vibrations, minimizing the noise produced.
Moreover, steel rails are designed with specific profiles that ensure proper alignment and stability of the train. This alignment reduces the lateral movements of the wheels, preventing excessive noise caused by wheel squeal or flanging. The flange of the wheel rubbing against the rail can create a screeching noise, which is minimized by using steel rails.
Additionally, regular maintenance and lubrication of steel rails further reduce noise. Lubricating the rail joints and curves decreases friction, minimizing the noise generated as the train passes over these areas.
Furthermore, steel rails are often supported by sleepers or ballast, which act as a cushioning layer. This layer absorbs some of the vibrations generated by the train, reducing the noise transmitted to the surrounding environment.
In conclusion, steel rails contribute to noise reduction in railway tracks through their smooth surface, high density, stiffness, proper alignment, and maintenance practices. These factors minimize friction, dampen vibrations, and reduce the overall noise generated by the train, making railway tracks quieter and more pleasant for nearby residents and passengers.
Steel rails contribute to noise reduction in railway tracks through several factors.
Firstly, steel rails have a smooth surface which reduces the friction between the wheels of the train and the track. This smooth contact between the train and the rails significantly reduces the noise generated. In contrast, if the tracks were made of materials like wood or concrete, the rough surface would create more friction, leading to increased noise.
Secondly, steel rails have a high density and stiffness, which helps in dampening the vibrations caused by the moving train. These vibrations can generate noise that propagates through the air and the ground. The high density of steel absorbs and dissipates the vibrations, minimizing the noise produced.
Additionally, steel rails are designed with specific profiles that ensure proper alignment and stability of the train. This alignment reduces the lateral movements of the wheels, preventing excessive noise caused by wheel squeal or flanging. The flange of the wheel rubbing against the rail can create a screeching noise, which is minimized by the use of steel rails.
Moreover, steel rails undergo regular maintenance and lubrication to further reduce noise. Lubrication of the rail joints and curves reduces the friction, minimizing the noise generated as the train passes over these areas.

In summary, steel rails contribute to noise reduction in railway tracks through their smooth surface, high density, stiffness, proper alignment, and maintenance practices. These factors minimize friction, dampen vibrations, and reduce the overall noise generated by the train, making railway tracks quieter and more pleasant for nearby residents and passengers.
Steel rails contribute to noise reduction in railway tracks through their characteristics and design. Steel rails have a smooth and hard surface, which reduces friction and vibrations caused by train wheels. This reduces the overall noise generated by the train as it moves over the tracks. Additionally, steel rails are designed to be sturdy and secure, preventing any loose or shaky connections between the tracks. This stability further minimizes noise by preventing any unnecessary movement or rattling of the tracks.
