High-speed rail lines, at ever increasing speeds and distances, are in development both in the UK and world-wide, but up-front capital expenditure can potentially be a major inhibiting factor both to the client and also in the eyes of the public. Cost reductions for these lines could be achievable if the initial costs of the physical construction, the duration of construction and the land take could be reduced. All three of these costs can potentially be reduced for embankments if the industry were to move towards a novel embankment replacement system. In addition embankment replacement systems could significantly improve the performance of the track structure as the dynamic properties of the contained material can be better controlled. However, such technology requires significant performance evaluation and the development of appropriate design guidance before UK industry can justifiably implement it in a project. This project therefore aims to evaluate and produce design guidance for two novel embankment replacement systems as a means to potentially reduce the cost of constructing new high-speed railway lines (particularly in urban environments) and improve the overall track behaviour and hence passenger experience.

英国和世界各地都在开发高速铁路，其速度和距离不断增加，但前期资本支出可能成为客户和公众眼中的主要抑制因素。如果能够减少实体建设的初始成本、建设持续时间和土地占用，那么这些线路的成本就可以降低。如果该行业转向新型路堤更换系统，那么路堤的所有这三项成本都有可能降低。此外，路堤更换系统可以显着提高轨道结构的性能，因为可以更好地控制所含材料的动态特性。然而，这种技术需要进行大量的性能评估并制定适当的设计指南，然后英国工业才能在项目中合理地实施它。因此，该项目旨在评估和制定两种新型路堤更换系统的设计指南，作为潜在降低建设新高速铁路线（特别是在城市环境中）成本并改善整体轨道行为和乘客体验的一种手段。
