i) The difference is in the structure gauge (height and width of the railway system), the design of the embankment, the formation width and specifications of materials, methodology of construction among others.
ii) Use of Chinese standards results in infrastructure that is more durable, more robust and that has higher safety margin.
iii) Over the last 30 years, China has built more railways than the rest of the world combined. Therefore, Chinese railway technology is proven in the industry.
