As the railway trains are improving their speeds all sidely, the Railway Ministry has enhanced technological checking and acceptance to the all kinds of repairs of railway vehicles in order to make the vehicles safe. We will use computers and automation to test the key places, such as the brake of railway freight wagons, so as to reduce the testing result that people will do. In order to make the trains move safely, it is very important for us to test the brakes of vehicles. Under this background, the instrument of intellectual experimental single car in railway vehicles is invented. It is closed , controlled and tested automatically; it can display the whole process that the vehicles brake is testing; it can be mastered and operated by workers; the flexible operation procedure is adapt to different production requirements; automation is still at a very high level, the testing is efficient; the network of data is connected, the management is scientific. We have done a lot of valuable explorations to make the experiment of railway vehicles single car have intellectual power.
