On June 24, 2009, the National Development and Reform Commission approved the proposal for the second double-track project of Lanzhou-Xinjiang Railway [3], including: the whole line is designed according to the national railway grade I and double-track electrification, and the speed target value is 200 km/h, of which 250 km/h is reserved for off-line projects from Lanzhou to Xining and Hami to Urumqi [4]. The newly-built railway is a trunk railway that pays equal attention to both passenger and freight recently. As the main railway channel connecting the three northwestern provinces with the mainland, the long-term will be mainly passenger transport, taking into account freight [5]

Moreover, it has been included in the national "Twelfth Five-Year" comprehensive transportation system planning (201March 2).

It can be seen that the project is actually the Lan Xin Express Railway: 1) The original project was the national railway level, which was lower than the high-speed railway level in China, and the highest category in the national railway level was the express railway. 2) The speed of on-line engineering is 200 kilometers per hour, which is also the standard of high-speed railway, which is lower than that of China (many people call high-speed railway). 3) The off-line project is complicated: the speed of Xining-Hami section is 200 kilometers per hour, and the conditions of Lanxi section and Hawu section are reserved for 250 kilometers per hour, which is generally also the condition of fast railway. -There are rumors that the underground foundation is 350 kilometers, which is not in conformity with the project approval document, and no evidence of the revised version is provided. 4) Passenger and cargo use. -People call the project Lan Xin Second Line Lan Xin High-speed Railway, which is a misunderstanding or a good wish before upgrading.
