既有线提速技改的可行性探讨

Feasibility Study of Raising Speed and Technical Innovation on Current Railways

我国铁路旅客列车基本以低速运行，必须提速才具有竞争力。参考各国提速经验，京秦线结合投资、工期以及线路等情况，对道岔、曲线、道口、通信、信号、机车和车站等作了统筹考虑，不搞“一刀切”，为既有线提速提供了经验。

Basically,the passenger trains in China travel at a low speed.Only by raising speed,they are competitive.The switches,curves,road junctions,communications system,signal system,etc.on Jing qin railway were arranged comprehensively by combining with the experience of raising speed in other countries,and the investment,building period,the railway condition of this railway.It was not made to accord with a same standard.Some experience was given for raising speed on current railways.
