报告摘要：

With increasing climate variability, railway infrastructure in tropical climates faces heightened risks from flooding and extreme heat, which can destabilize tracks and increase the likelihood of derailments. This research bridges analytical modeling with real-world applications to develop resilience strategies specifically targeting flood-induced instability and track buckling under extreme temperature. Through a combination of simulations and field data collection, critical vulnerabilities in railway tracks are assessed, with findings directly linked to practical, field-based solutions. A machine learning-driven predictive maintenance model has been developed to forecast deterioration in high-risk areas, enabling proactive maintenance and risk mitigation. Analytical results are validated with real-world case studies to confirm the effectiveness of proposed solutions, including strengthening strategies and maintenance plans, under operational conditions. This approach equips track engineers with actionable insights to minimize accidental risks and enhance railway resilience against climate-induced disruptions, supporting the reliability and safety of rail networks in increasingly extreme environments.
