Abstract

Railway tracks represent one of the most expensive assets for railways, and constant studies aim to extend their useful life. This work proposed equations for W1, W2, and W3 (variation of rail billet dimensions vertically, horizontally, and with an inclination of 45°) to understand wear and tear. Using real data, the equations were developed and applied to an eight-year-old rail, revealing significant differences between measured and expected values. This discrepancy can be attributed to variations between railway sections and the statistical model used. It is suggested that a more detailed approach consider individual characteristics of each section and additional variables. This highlights the need for personalized analysis of track wear, considering the diversity of conditions along the railway.
