It is an important part of the "eight vertical and eight horizontal" high speed railway network in the national medium and long-term railway network planning, including the (yinhaitong) road. It is of great significance to form Xi'an "Mi" shaped high-speed railway hub, improve the structure of the railway network in the central and western regions, and realize the interconnection of the national high-speed railway network. Yinxi high speed railway is also the first high-speed railway for poverty alleviation in China. After its completion, the operation time of Xi'an Yinchuan railway will be shortened from 14 hours to 3 hours.
