Authors: Gaurav R. Khairnar, Shailesh P. Palekar

Abstract: High-speed rail systems generate significant ground-borne vibrations that can lead to structural damage, discomfort to nearby residents, and accelerated deterioration of railway components. This review investigates various vibration mitigation strategies used in high-speed rail infrastructure, focusing on track and material modifications. Key techniques include the application of resilient rail pads, ballast mats, floating slab tracks, and subgrade treatments. Each method's effectiveness is analyzed based on experimental findings, numerical simulations, and field data. Among these, resilient rail pads are highlighted for their practicality and ease of implementation, offering effective vibration isolation without extensive structural changes. However, the success of mitigation efforts depends on factors such as train speed, soil conditions, and system design. The paper concludes looking at what we still don't know and suggests using several different solutions together to get better results. This review aims to guide engineers and researchers in developing efficient, site-specific vibration control solutions for high-speed rail systems.
