The key project of capacity expansion and transformation of Qinghai Shuangzhai Logistics Base has been completed, and the annual loading and unloading capacity has been increased to 5 million tons.

China News Service, Xining, September 24 (Qi Zengbei, Ma Fugui, Yongping) In the early morning of September 23, the key project of capacity expansion and transformation of Qinghai Shuangzhai Logistics Base was successfully completed. The construction of 17 sets of turnouts and rail replacements came to a successful conclusion through the signal interlocking test, marking the completion of the core facilities upgrade of Qinghai's only railway secondary logistics base.

As an important logistics node in the northwest road network, after the completion of this upgrade, the distribution capacity of Qinghai Shuangzhai Logistics Base has achieved a qualitative leap. The annual loading and unloading capacity has been increased from 3 million tons to 5 million tons, and the cargo storage area has reached 104,000 square meters, which can satisfy the operation of 396 vehicles at the same time.

It is reported that the Shuangzhai Logistics Base was formerly the Shuangzhai Goods Yard put into operation in the 1980s. In order to adapt to the continuously growing regional logistics demand, the base has launched an all-round upgrade since March 2024. Through the construction of new arrival and departure lines, cargo operation lines, platforms and warehouses, a complete modern railway logistics infrastructure system has been built.

The Shuangzhai Logistics Base turnout connects the Lanqing Railway and the base's entry and exit contact line, which is directly related to the station's passing capacity, train destaging efficiency and freight train receiving and dispatching quality. Affected by the plateau climate and heavy-duty transportation, the base's original turnout rail parts suffer from frequent wear, cracks and other diseases, and the equipment is insufficiently stable, which restricts freight efficiency and operation and maintenance safety.

According to reports, this construction started in early September, mainly replacing 17 sets of turnout rail parts, and simultaneously completing the upgrade and transformation of signal switch equipment. Among them, the replacement of three sets of the most difficult cross-over line switches can completely eliminate hidden dangers of joint diseases, reduce the workload of later operation and maintenance, and improve the quality of the line.
