Study on the technologies development trend of high speed EMUs

High speed railway technologies are rapidly development in the world. The total distance of the high speed railway is more than 40,000 kilometers in China, and many types of high speed Electrical Multi-Units (EMUs) are operated. The top operation velocity of the train reaches 350 km/h. New science and technologies are developing rapidly. New generation technologies such as the information technology, intelligent manufacturing, new material and processing, innovating design philosophy have revolutionary influence on the high speed train. It promotes the high speed train performance such as intelligence, reliable operation and environment-friendly. Based on many years investigation of the trend of the technology development and requirement of general public, the trend of technology development in five aspects are presented in this paper. The five aspects include economic applicability, high speed and high efficiency, green and low carbon, intelligent safety, comfortable and high quality.
