Study on Top-level Design Specifications of High-speed Trains

The design of high-speed train is based on its general technical specifications which are decided in turn by its top-level design specifications.According to the design goals of high-speed train,the top-level design specifications were studied in this paper in four aspects,i.e.,the transport capacity,riding comfort,safety and environment-friendliness.Through the research of formulation basis of technical specifications and analysis on relationships of technical specifications,the top-level design specifications for high-speed trains were presented.
