Background

Rail transit refers to a type of vehicle or transportation system in which operating vehicles need to travel on a particular rail. The most typical rail transit is a railway system consisting of conventional trains and standard railways. With the diversified development of trains and railway technologies, rail transit presents more and more types, not only extends over long-distance land transportation, but also is widely applied to middle and short-distance urban public transportation, common rail transit includes traditional railways (national railways, intercity railways and urban railways), subways, light rails and tramcars, and novel rail transit includes magnetic suspension rail systems, monorail systems (straddle type rail systems and suspension type rail systems), passenger automatic rapid transit systems and the like. In the Chinese national standard, the term commonly used in urban public transport is defined as the general term of rapid mass transit which usually uses electric energy as power and adopts a wheel-rail running mode.
