| Abstract: | From civil engineering point of view, the paper analyzes differentfactors that result in different initial speed of new line. The paper also gives thegeneral calculation method for the increase of investment demanded by differentfactors. Taking Jiao-Xin line as example, the paper calculates the difference ofcivil engineering cost between the initial speed of 140km/h and 60km/h. It thenanalyzes the cost and benefit and studies its economical feasibility. At the end,it discusses on the choosing of target speed value according to different typesof newly opened railways. |
