200 km Per Hour一The Best Choice for Beijing - Shanghai Express Railway

Li Yushan

Strategic Study of CAE 2004, Volume 6, Issue 12, Pages 7-12

Abstract: from China's actual conditions, holds that in the construction of Beijing — Shanghai express railwayThe paper maintains that the electrified fast-speed wheel/rail system with a speed of 200 km per hourshould be the best choice for China*s railway development.In the time with increasing energy crisis, the maglev train with speed of 400 km per hour and the high-speedrail system with speed of 300 km per hour will lead to the unbearable wastes of socio-economic resources
