High-speed trains on the Shanghai to Tongchengdong (Tongcheng East) route offer Second, First, and Business Class seating, with reserved seats throughout. Most services depart from Shanghai Hongqiao and run via Nanjing South and Hefei South before reaching Tongcheng East. The fastest option is the G-series Fuxing service (CR400/CRH380 sets), which reaches up to 350 km/h (217 mph) on the Shanghai–Nanjing and Hefei–Tongcheng East high-speed sections, with operations around 250 km/h (155 mph) between Nanjing South and Hefei South. Typical end-to-end journey times are about 3 hours 20 minutes to 3 hours 50 minutes, depending on stops. Key intermediate stations often include Suzhou North, Wuxi East, Changzhou North, Zhenjiang South, Nanjing South, and Hefei South, with limited-stop patterns running faster. In comparison, some D-series Hexie high-speed services and G-trains with more intermediate stops operate at 200–250 km/h (124–155 mph) and usually take 30–50 minutes longer. Onboard, expect power outlets, luggage racks, and clean restrooms; seating is 2+3 in Second Class, 2+2 in First Class, and 1+2 in Business Class, the latter offering wider seats and a quieter cabin for a more premium experience.
