High-speed services link Shanghai and Zhenjiang throughout the day, with most departures from Shanghai Hongqiao to Zhenjiang South. The fastest option is the G-series Fuxing (often CR400 sets), operating on the Beijing–Shanghai High-Speed Railway at up to 350 km/h (217 mph), typically cruising between 300–350 km/h (186–217 mph) on this section. These trains complete the journey in about 50–60 minutes with limited stops such as Suzhou North, Wuxi East, and Changzhou North. Seating includes Second, First, and Business Class, with power outlets, overhead luggage racks, and on many sets onboard Wi‑Fi. In comparison, D-series Hexie trains (commonly CRH2/CRH5) run at 200–250 km/h (124–155 mph). They make more intermediate stops and may use either Zhenjiang South or the central Zhenjiang station, with departures from Shanghai Hongqiao or Shanghai (city) station. Typical travel time ranges from about 1 hour 20 minutes to 1 hour 50 minutes. D-series services usually offer Second and First Class seating and similar modern amenities. Choose a G-series Fuxing for the quickest run, or a D-series Hexie if you prefer access to the city-center station or a wider range of stopping patterns.
