高铁的英语是High-speed Railway。
高速铁路，简称高铁，是指设计标准等级高、可供列车安全高速行驶的铁路系统。其概念并不局限于轨道，更不是指列车。
中国国家铁路局颁布的《高速铁路设计规范》文件中将高铁定义为新建设计时速为250公里（含）至350公里（含），运行动车组列车的标准轨距的客运专线铁路。中国国家发改委将中国高铁定义为时速250公里及以上标准的新线或既有线铁路，并颁布了相应的《中长期铁路网规划》文件，将部分时速200公里的轨道线路纳入中国高速铁路网范畴。
总体特点
适合高速铁路的生存环境其实只有两条基本原则：第一是人口稠密和城市密集，而且生活水准较高，能够承受高速轮轨比较昂贵的票价和多点停靠，第二是较高的社会经济和科技基础，能够保证高速轮轨的施工、运行与维修需要。
就这两点而言，以巴黎和柏林为核心的欧洲大陆、日本密集的城市带和中国大型的城市群是最适合不过的。因此世界最先进的高速轮轨技术诞生在德、法、日这3个国家并在中国大规模展开就非常合乎逻辑。

It is a really hot topic now as many city had opened high-speed railway.Many people said that high-speed railway is much better than the other transportation .and as also some people believe that it is no future .to my point of view ,high-speed railway bring us real convenient .My reasons are as follows:First ,the stations of the high-speed railway are much closer to our living area ,like buses .and it is much more convenient to transport goods .for example ,a businessman in Shanghai want go to Sichuan with 1000kg goods,if he go to Sichuan by plane ,he need go to suburbs because the airports always in the suburbs,and it cost much money to checked the goods.if he go by train ,he need to go to the railway station far away from home ,and the train take much more time .and if he take bus,though it is convenient,it not only cost much money ,but also waste much time.Secondly,the most important disadvantage of high-speed railway is that it need a great number of passengers .As the second most populous countries of the world,Chinese has no pressure.What's more ,China is developing in a "high speed",even though high-speed railway cost much money ,I believe China can hold it .As all above ,I firmly believe that the future of high-speed railway is shinning!
