Research on Tilting Control System of Tilting Train

To spend up passenger trains and cut journey time are one of the targets of the world railway modernization, and also a means to increase competition in transportation market. In China, many railway lines in mountainous areas, which account for two thirds of total area, have been designed with heavy gradient and curves with small radius. It is difficult to improve them and it takes high cost to upgrade them. In order to increase the competitiveness of the existing railways, the running speed of railway passenger trains should be raised on a large scale. Operating titling trains can meet the above purpose. Many countries have developed the technology of tilting trains. In this paper, relative key technical problems such as curve defection, train control network, tilting actuator etc. are discussed. Also presented is the development of the first tilting control system in China.
