At 23:55 on February 8, high-speed train D4384 smoothly departed from Shanghai Hongqiao Station and arrived at Yancheng Station at 01:39 the next morning. This late-night train marks the official launch of the red-eye high-speed rail service between Yancheng and Shanghai. It also highlights Yancheng's growing role as a new nighttime transport node in the Yangtze River Delta, bringing it closer in time and space to central cities.

The launch of the red-eye high-speed rail directly responds to passengers' strong demand for efficient and flexible travel. For many passengers, the night high-speed rail offers a brand-new travel option. It not only effectively eases daytime transportation pressure during peak periods such as the Spring Festival travel rush, but also precisely meets the practical needs of off-peak and emergency trips, opening a new time window for personnel mobility in the Yangtze River Delta.

This night-time railway artery enables Yancheng to integrate into the Yangtze River Delta integration process at a deeper level and around the clock. It breaks the time limits of traditional transportation, promotes the efficient flow of talents, capital, information and other factors at night, and injects new vitality into industrial coordination, cultural and tourism interaction, and public welfare sharing between Yancheng and Shanghai, as well as the entire Yangtze River Delta region.
