With the comprehensive completion of the main project, the key railway passage at the border between Ningxia and Inner Mongolia has reached a critical construction node. The Yinba Railway has officially launched static acceptance, and the entire project has entered the final verification stage, laying a solid foundation for subsequent operation and activating the transportation and economic vitality of the northwest border.

The entire line is undergoing comprehensive verification

On August 25, 2026, the main construction of the Yinchuan to Bayanhot railway was completed, and the project officially entered the static acceptance stage, smoothly entering the critical period of completion acceptance. As an important branch line of the Baotou Yinchuan high-speed railway, this railway has a total length of about 111 kilometers and a designed speed of 200 kilometers per hour. The line connects multiple places in Yinchuan, Ningxia, crosses the Helan Mountains to reach Alxa Left Banner, Inner Mongolia, and opens up a new land transportation channel between Ningxia and Mongolia.

This static acceptance is the core quality inspection link before the railway is opened to traffic. The construction unit has formed a professional acceptance team, strictly following the national railway construction standards, conducting comprehensive inspection and testing of track bridges and tunnels, communication signals, power equipment, station facilities, and safety protection systems. The project details are checked item by item, and the construction quality is comprehensively verified to ensure that all indicators of the line meet the mandatory requirements for opening to traffic operation.

Assist in improving the quality of development in Northwest China

After the static acceptance is completed, the project will orderly advance a series of finishing work such as joint debugging and testing, operational testing, preliminary acceptance, and safety assessment, steadily advancing the preparation process for opening to traffic. The Yinba Railway focuses on regional passenger transportation exchange, taking into account intercity transportation functions, effectively filling the gap in the local railway network in the northwest, and improving the layout of the high-speed railway network in the northwest region.

After the completion and operation of the line, it will significantly shorten the time and space distance between Ningxia and Alxa region in Inner Mongolia, strengthen the linkage between the two regions' industries, cultural tourism, and people's livelihoods, effectively support the high-quality economic and social development of border areas, and inject new momentum into the interconnection and regional coordinated development of the northwest region.Editor/Min Jing
