State of the art and Future Trend of Railway Transportation Traction Power
Taking the types of transportation as the starting point of the paper,the composition of the railway transportation system was in-troduced,and the types and technical characteristics of railway traction power were elaborated in detail.The traction power of railway trans-portation in China is mainly composed of Steam locomotive,Diesel locomotive and Electric locomotive.Due to the limitation of technical advantages,electric traction has been greatly developed in China,and railway electrification has been fully realized.The trunk line trans-portation is basically driven by Electric locomotive.However,as a kind of self-sufficient locomotive with mature technology,Diesel loco-motive still has certain application prospects at this stage.It is less affected by weather,natural disasters and war damage,so it plays an im-portant role in shunting operations and railway disaster relief.Considering the increasing depletion of petroleum resources,it is imperative to adopt alternative fuels and develop new self-sufficient locomotives such as gas turbine locomotives,fuel cell locomotives,and hybrid electric locomotives.
