Niu, Liubin (author), Yang, Fei (author), Deng, Xiangyun (author), Zhang, P. (author), Jing, Guoqing (author), Qiang, Weile (author), Guo, Y. (author)In practice, the assessment and treatment of rail corrugation are quantitatively based on the corrugation depth. Wheel–rail vertical forces (WRVF), as a direct reflection of wheel–rail interaction, can give expression to the corrugation depth and thus serve as a key parameter for assessing the corrugation. In this paper, we propose an...journal article 2023

Shi, Can (author), Fan, Zheng (author), Connolly, David P. (author), Jing, Guoqing (author), Markine, V.L. (author), Guo, Y. (author)Railway ballast performance is dictated by a complex mix of mechanical properties. These effect its performance at the particle level for example in terms of particle degradation, but also at the track system level in terms of settlement and stability. Therefore this paper seeks to develop new understandings of ballast behaviour and identify...review 2023

Zhao, Wenbo (author), Qiang, Weile (author), Yang, Fei (author), Jing, Guoqing (author), Guo, Y. (author)Ballast layer defects are the primary cause for rapid track geometry degradation. Detecting these defects in real-time during track inspections is urgently needed to ensure safe train operations. To achieve this, an indicator, the track degradation rate (TDR) was proposed. This rate is calculated using track geometry inspection data to locate...journal article 2023
