On the Shanghai to Dandong route, travelers typically choose between a fast high-speed connection with one change and a direct overnight sleeper on the classic network. High-speed services use G-series Fuxing trains on the main corridors from Shanghai Hongqiao toward Beijing and Shenyang, running at up to 300–350 km/h (186–217 mph). The connecting leg from Shenyang to Dandong is operated by D- or C-series trains at 200–250 km/h (124–155 mph). With a change at Beijing Chaoyang or Shenyang, total daytime travel usually takes about 7.5 to 9 hours, depending on the connection. Seating on these trains includes Second, First, and Business Class, with power outlets and trolley service. By contrast, direct overnight Z/T/K trains on the conventional line connect Shanghai with Dandong without transfers. These run at 120–160 km/h (75–99 mph) and typically take around 20 to 26 hours. They offer Hard/Soft Sleeper berths as well as Hard/Soft Seat options, providing the advantage of an overnight journey and wider berth varieties. Choose the high-speed combination for the quickest daytime trip, or the classic sleeper for a direct, budget-friendly overnight ride.
