On September 22, workers were busy at the Nanjing-Huai'an Intercity Railway project site in its Hongze section in Huai'an, Jiangsu province. As a key component of the Yangtze River Delta intercity railway network, the line will, upon completion, shorten travel time between Nanjing and Huai'an to just one hour, facilitating mobility for local residents and contributing to coordinated regional development.
