成达万高铁 首批500米长钢轨顺利进场

Group 1 - The Chengda-Wan High-Speed Railway (成达万高铁) has entered the long rail storage phase, with the arrival of a train carrying 500-meter long steel rails at the Nanchong North laying base, laying the groundwork for subsequent track laying construction [1] - The Nanchong North laying base covers an area of approximately 52,000 square meters, with the first batch of 50 rails weighing a total of 1,500 tons, capable of laying 12.5 kilometers of track [1] - The use of 500-meter long rails significantly reduces track joints compared to traditional short rails, enhancing train operation stability and safety [1] Group 2 - The Chengda-Wan High-Speed Railway is a crucial part of China's "Eight Vertical and Eight Horizontal" high-speed rail network, stretching 477 kilometers from Chengdu to Wanzhou, with a design speed of 350 kilometers per hour [2] - Upon completion, the railway will provide a convenient passenger transport corridor from Chengdu to the Central Plains and Beijing-Tianjin-Hebei regions, playing a significant role in promoting the Chengdu-Chongqing economic circle and the development of the Yangtze River Economic Belt [2]
