On a bright spring day, the construction site of the Hefei hub for the new Shanghai-Nanjing-Hefei High Speed Railway is abuzz with activity. Workers are making full use of favorable weather conditions to advance the project with high standards and quality. As a key segment of China's "Eight Vertical and Eight Horizontal" high-speed rail network along the Yangtze River corridor, the railway will provide a fast and direct link between northern Yangtze cities and the Nanjing and Shanghai metropolitan areas once operational.
