The Lanzhou-Qinghai Railway, with a total length of 216 kilometers, is China's first railway leading to the Qinghai-Tibet Plateau. Regular track renewal along this section is a crucial measure to enhance line quality and ensure the safe operation of trains. The HGCZ-2000 rapid track renewal vehicle is 31.48 meters long, weighs 77 tons in total, and weighs 92 tons when fully loaded with fasteners. It integrates track renewal and fastener recycling, significantly improving the working efficiency.
