高速铁路的主要技术特征与高速动车组

Main technical characteristics of high speed railway and high speed EMUs

全面比较了高速铁路与既有铁路的主要技术不同点,指出高速铁路的主要技术特征体现在:持久高平顺性的轨道,大张力的接触网,车载信号为主的列车控制系统,轻量化、流线型、密封的、大功率和大制动能力的交直交电动车组。同时,介绍了国外最新投入和即将投入运营的电动车组。

Main technical differences of high speed railways and existing railways are compared. It is pointed out the main technicalcharacteristics of high speed railways: highly regular track, high-tension catenary, train control system based on on-board signals as well asweigh-lighting, streamline and sealed AC-DC-AC EMUs with high power and high braking capacity. Foreign EMUs newly put intooperation and to be put into operation soon are introduced.
