On Developing High-Speed Evacuated Tube Transportation in China

The necessity and feasibility of evacuated tube high-speed transportation were discussed . The fundamental problems of this technology, e.g. pressure in the tube, coefficient of coverage and other related techniques, were analyzed in detail. More discussed were the strategy and technical choice of developing this kind of transportation in China. The system consisted of partial pressure in tube, high-temperature super conducting magnetic levitation and synchronic linear motor traction is proposed to be the variant of developing research, so that the 600-1 000 km/h high-speed evacuated tube train might be able to run commercially by 2030.
