en.Wedoany.com Reported - At midnight on June 1, as train G55302 departed from Nanchang West Station heading to Nanchang South Station, it marked the entry of the Nantang Connecting Line in Nanchang, Jiangxi, China, into the trial operation phase. Trial operation is a "real-world drill" before a railway line is officially opened. During this phase, the railway department will conduct a series of project tests, including parameter tests for the minimum tracking interval of trains, simulated equipment fault handling, and emergency rescue drills, providing scientific basis and safety assurance for the official opening and operation.
Le Zhigang, Deputy Director of the Transportation Department of China Railway Nanchang Group Co., Ltd., stated that by simulating formal operation scenarios and full-load train operations, the railway department will comprehensively test the new line's operational organization capabilities, train operation capabilities, and equipment support capabilities. The Nantang Connecting Line starts from Nanchang South Station and ends at the Tangcun Signal Station on the Changfu Railway. It is a double-track electrified railway with a design speed of 200 km/h, an up line length of 15.66 km, and a down line length of 15.94 km, with a bridge-tunnel ratio as high as 96%.
This project is the first in China to implement a new line connection on the mainline bridge of an existing high-speed railway in operation. During the construction process, the participating units overcame a series of technical challenges, including multi-line parallel crossings, protection of existing lines, and modification of high-speed railway bridges. The project commenced construction in March 2022 and is expected to be ready for operation by June 2026. The Nantang Connecting Line serves as the core link in the "three main and two auxiliary" passenger transport layout of the Nanchang Railway Hub, connecting major railway lines such as the Shanghai-Kunming, Beijing-Hong Kong, Hangzhou-Changsha, and Beijing-Kowloon railways.
Once this railway line is completed and opened to traffic, trains departing from Nanchang Station and Nanchang East Station heading to Changsha can directly travel via the Nantang Connecting Line onto the Shanghai-Kunming High-Speed Railway, making passenger travel smoother and more efficient. This is of great significance for improving the layout of the Nanchang Railway Hub, enhancing regional railway transport efficiency, facilitating travel for residents along the line, and promoting the high-quality development of the Yangtze River Economic Belt.
