Research on the Railway Line Carrying Capacity Based on Pattern Train Work Diagram

In order to achieve the leaping development,the railway transport enterprises are updating the railway equipment constantly in china,accordingly,great changes in transport organization mode are taking place.It is obviously unreasonable that the carrying capacity calculation method based on freight train is adopted in the railway lines on which there are more passenger trains than freight trains or all the trains are passenger trains.In view of this,based on pattern train work diagram,a new capacity calculation method,taking speed combination as the core,was proposed.And as an example,the carrying capacity of Chengdu-Suining railway was calculated and analyzed.
