A Study on Speed Regulations in Accordance with Speed-up for Tilting Train

틸팅차량 속도 향상에 따른 규정(안) 연구

In order to improve the speed of railway, several parameters and/or technical issues, which are affecting speed improvement negatively, need to be considered in addition to the enhancement of physical performance of the railway system such as maximum speed, speed at curve, and speed at turnout track. The parameters under complicated situation of railway system are from the areas of rolling stocks, track, power system, signalling, etc. In general, two different aspects of technical issues can be evaluated; Technical issues in the hardware aspect and technical issues in the software aspect. The hardware parameters include running performance, braking performance, and power performance, while the software factors are rules, regulations, and riding quality. In this investigation, a comparison study between hardware and software aspects in technical issues was conducted to provide technical information on the amendment of railway speed-up regulations.
