What is rail wear?

Rail wear refers to the gradual reduction in the rail profile that occurs as a result of constant train passage over the tracks. This wear can manifest as changes to the shape and surface of the rail, primarily due to the repetitive forces exerted by the wheels of trains. Over time, this can lead to a decrease in the rail’s ability to support trains effectively and safely. Monitoring and managing rail wear is critical for maintaining track integrity and ensuring safe operations on the railway network.

In contrast, cleaning the rails from dirt is a maintenance activity aimed at enhancing traction and preventing additional issues rather than a description of rail wear itself. Annual inspections, while vital for safety and maintenance, focus on evaluating the overall condition of the track rather than the wear and degradation of the rails specifically. Designing tracks to reduce weight is an engineering consideration that addresses other concerns, such as construction and operational costs, and does not pertain directly to the phenomenon of wear.
