On the Shanghai to Dangshan route, the quickest option is the China Railway high-speed G‑series to Dangshan North (砀山北). These trains typically run Shanghai Hongqiao → Xuzhou East → Dangshan North, using the Beijing–Shanghai High-Speed Railway and the Zhengzhou–Xuzhou High-Speed Railway. Fuxing sets (CR400AF/BF) and some Hexie CRH380 trains operate at up to 350 km/h (217 mph) between Shanghai Hongqiao and Xuzhou East, then up to 300 km/h (186 mph) toward Dangshan North. Depending on whether the service is through-running or requires a same-station change at Xuzhou East, total travel time is about 3 h 30 m to 4 h 30 m. Onboard classes include Second, First, and Business Class, with reserved seating, power outlets, and trolley service. Classic conventional trains (Z/T/K-series) also link Shanghai or Shanghai South with Dangshan (city station) on the non‑HSR network via Nanjing and Bengbu. These run at around 120–160 km/h (75–99 mph) and usually take 7–10 hours, including overnight options. Seating and sleeper choices include Hard/Soft Seat and Hard/Soft Sleeper. High-speed services are best when heading to Dangshan North for the shortest time, while conventional trains suit travelers who prefer a direct arrival at Dangshan’s central station or an overnight schedule.
