Core Viewpoint - The Long-Luzhou-Xuyong Railway, a crucial part of the Western Land-Sea New Corridor, is set to be completed and operational by the end of 2025, significantly enhancing freight efficiency and connectivity for Sichuan's goods to reach the sea [1][3]. Group 1: Railway Specifications and Improvements - The railway's design speed has been increased from 60-80 km/h to 120 km/h, which will greatly improve freight transport efficiency [1][2]. - The existing railway line of 161 kilometers has been optimized by straightening curves, reducing the total length by approximately 600 meters in certain segments [1]. - The new line features a track quality standard controlled to 2 mm, surpassing the national standard of 12 mm for conventional railways, enhancing safety and passenger comfort [2]. Group 2: Strategic Importance and Connectivity - The Long-Luzhou-Xuyong Railway connects the southern Sichuan region to the Western Land-Sea New Corridor, which is a key international logistics route linking the Silk Road Economic Belt and the 21st Century Maritime Silk Road [3]. - The Western Land-Sea New Corridor includes three railway routes, with the western route being the shortest at 1367 kilometers, and the Long-Luzhou-Xuyong Railway will further shorten this route by about 300 kilometers [3]. - Once operational, the railway will serve as the most convenient freight transport route from Sichuan to the Beibu Gulf Economic Zone in Guangxi, significantly reducing freight transport time by nearly 4 hours [3].
