Faster, faster, faster

摘要

Imagine a world where you can travel at 500 km/h between major cities relaxing in comfortable seats, sipping a glass of wine, working on the laptop and walking to the buffet car. My work involves modeling the challenges that high-speed represents such as track dynamics and passenger comfort combined with minimising ground vibration and developing track forms that are fit for high capacity loading with the minimum of track maintenance requirements. At these high speeds we need to think about analysing the train and track as a combined system, i.e. we need to adopt an holistic approach to look at how the train is interacting with the ground and vice a versa.
