The work investigates how track characteristics and quality impact performance under real operational conditions, and identifies key factors driving degradation and reliability risks. Advanced machine learning is leveraged to model these dynamics, enabling real-time assessment of track conditions and improving ride-comfort evaluation. Results show strong performance from CNN variants, with dilated CNN achieving the best predictive fit and supporting robust, efficient computation.","University of Birmingham  \nRailway track quality, safety and reliability through train-track dynamics and advanced machine learning  \nHuang, Junhui; Kaewunruen, Sakdirat  \nLicense:  \nCreative Commons: Attribution (CC BY)  \nCitation for published version (Harvard):  \nHuang, J & Kaewunruen, S 2023, 'Railway track quality, safety and reliability through train-track dynamics and advanced machine learning', Clarke Lecture 2023, Birmingham, United Kingdom, 22/06/23-22/06/23 .  \nLink to publication on Research at Birmingham portal  \nGeneral rights  \nUnless a licence is specified above, all rights (including copyright and moral rights) in this document are retained by the authors and/or the copyright holders.

Aug. 2026  \nRailway track quality, safety & reliability through traintrack dynamics and advanced machine intelligence Junhui Huang, Dr Sakdirat Kaewunruen, School of Engineering  \nResearch Questions  \n1. How do characteristics, quality and reliability of railway tracks impact system performance?  \n2. What are the key factors influencing the tracks in dynamic operational conditions?  \n3. What benefits of leveraging AI in enhancing the performance of track?  \n4. How can AI be applied to determine real-time track conditions?  \nContextual Background  \nRailway tracks are subjected to dynamic forces and environmental   factors.  \nAI can be used to monitor traintrack  \nMethods  \nResults  \n1. Both the performance of the standard CNN and dilated CNN are above 0 .90 .  \n2. Considered factors: two different model types, three sample size, irregularities included.  \n3. Dilated CNN produces the best R2 of 0 .97 on the longest sample size.  \nThe Findings in Context  \nNew mobile-phone App for Real-time Ride Comfort Assessment  \nAI models provide satisfied performance  \nFast calculation with full technical robustness  \nEasy to implement and to connect real-time via 5G  \nReducing cost,  \nand Empowering passengers  \nNew method  \nRobust  \nEasy to use  \nAccurate  \nConclusions  \n1. We have proposed a dilated CNN using the sensory data acquired from axle box which is immune to speed up to 120 km/h and bad weather conditions as there are sophisticated accelerometers designed to tackle the extreme weather conditions.  \n2. We have confirmed that the performance of the proposed model is highly satisfied, the dilated technique contributes to saving computational cost, and the consideration of irregularities makes no significant difference to the model's performance.  \n3. An implication of this study is the possibility that wireless accelerometers can be mounted onboard service trains.  \n4. New smartphone App has been developed to assess real-time ride comfort using machine intelligence.  \nKey ","cbCaioFwRMbgacXR","https://ap.wps.com/l/cbCaioFwRMbgacXR","pdf",874309,1,2,"English","en",105,"# Research Questions\n## Contextual Background\n## Methods and Results\n## The Findings in Context\n## Conclusions\n## Key Publications","[{\"question\":\"How do railway track characteristics affect system performance and reliability?\",\"answer\":\"The research addresses how track quality and reliability influence system performance, emphasizing the role of track-related characteristics in overall operational outcomes under dynamic conditions.\"},{\"question\":\"What AI approach is proposed for determining real-time track conditions?\",\"answer\":\"A dilated CNN model is proposed using sensory data acquired from the axle box, designed to remain effective under speed up to 120 km/h and adverse weather conditions.\"},{\"question\":\"What performance results and practical outputs does the study provide?\",\"answer\":\"The model yields strong accuracy (reported above 0.90 for CNN variants, with dilated CNN achieving best R² up to 0.97), and the study supports a mobile-phone app concept for real-time ride comfort assessment with fast, robust computation.\"}]","Railway track quality, safety and reliability through train-track dynamics and advanced machine learning -
