“…The research goal of rail transportation comprehensive test system, including two points, one is designed for China's rail transit new technology, new methods and new equipment with high quality, high precision, performance test platform, improve the safety guarantee for the reform and operation of rail transit in China; the establishment of a new technology and new rail transportation as to the equipment innovation center and talent development base, with deep research and development team and independent intellectual property development industry chain support for the rapid and sustainable development of urban rail transit in china [3]. At present, all countries in the world have invested a lot of manpower, material and financial resources to the construction of rail transportation comprehensive test center, to provide strategic support the prosperity and development of domestic rail transportation, the construction of the largest, the most abundant content of the experimental study on rail transportation comprehensive test center including the German Vikberg -Wilden Lasz test center the United States, the transportation technology center and the French transport research center [4][5]. In Germany Vikberg -Wilden Lasz test center as an example, establishment and operation of the test center can simulate all kinds of extreme scenarios and a full range of test run on rail transportation safety, stability, comfort, all equipment and technology for various types of rail vehicles and rail traffic system, such as rail transportation the network communication, vehicle track, track subgrade debugging and test precision, shorten the test period and test cost of rail transportation, reducing the German city rail transit operation cost, meet the urgent needs of rapid rail transit in response to the market.…”
