Review and prospect of maintenance technology for traction system of high-speed train

Abstract In the past few decades, high-speed trains have witnessed tremendous and vigorous development with appearance of oil crisis industrialization, which became a significant trend in transportation industry world over. With increase railway mileage, amount train has grown sharply, service life increased gradually components vehicle traction system become worn aged as result. Therefore, advanced maintenance technology its application are key factors to reduce cost, human resource input ensure safe, stable reliable operation trains. This paper summarizes discusses development, mode, management railways major countries world, especially condition-based electrical system, offers prospect research direction technology.
