The future of high-speed train
Proceedings Autonomous Decentralized Systems, 2005. ISADS 2005., 2005 High-speed intercity railways have grown into profitable business, achieving a renaissance in rail transport. High-speed railways need constant updating to new systems if they are to be winners in this age of competing transportation modes. In view of that situation, JR East started an R&D project to achieve even faster speeds-more than 300km/h. A test

A Review of Recent Research into the Causes and Control of Noise during High-Speed Train Movement
Applied Sciences, 2022 Since the invention of the train, the problem of train noise has been a constraint on the development of trains. With increases in train speed, the main noise from high-speed trains has changed from rolling noise to aerodynamic noise, and the noise level

Effects of bottom deflectors on aerodynamic drag reduction of a high-speed train
Acta Mechanica Sinica, 2022 Inspired by the fact that bogies and bottom equipment generally contribute a great deal of aerodynamic drag to high-speed trains, this paper puts forward a simple method of mounting some small deflectors before and/or after the bogie cabins to optimize ...

The Crystallization Behavior of TiO2-CaO-SiO2-Al2O3-MgO Pentabasic Slag with a Basicity of 1.1–1.4
Crystals, 2021 The utilization of titanium-containing blast furnace slag has been an unsolved problem for a long time. Failure to make effective use of the slag, which is caused by a high TiO2 content within it, not only results in a waste of resources, especially ...

Deep Deterministic Policy Gradient for High-Speed Train Trajectory Optimization
IEEE transactions on intelligent transportation systems (Print), 2021 This paper proposes a novel train trajectory optimization approach for high-speed railways. We restrict our attention to single train operation scenarios with different scheduled/rescheduled running times aiming at generating optimal train recommended ...
