One of the primary cost drivers of high-speed rail is the fact that the track must be far straighter and flatter than standard rail lines. In order to achieve this, far more earthworks, bridges and tunnels are required, which are extremely expensive. Hot Rails aims to use tilting trains to achieve high…

Although the track cost estimates in AECOM13 are reasonable, they are based on just one real-world example from Germany, and additionally are specifically for very high speed track (400km/h). The Hot Rails strategy only requires 200 to 250km/h quality track, for which the required tolerances and material strength is not so…
