High-speed services on the Shanghai to Shouxian route are mainly China Railway G-series (with some D-series) running from Shanghai Hongqiao via Nanjing South and Hefei South to Shouxian. Speeds reach 300–350 km/h (186–217 mph) between Shanghai and Nanjing on the Beijing–Shanghai HSR, then 250–300 km/h (155–186 mph) from Nanjing to Hefei on the Hefei–Nanjing passenger line, and about 250–300 km/h (155–186 mph) from Hefei South to Shouxian on the Shangqiu–Hefei–Hangzhou HSR. End-to-end travel typically takes about 3.5–4.5 hours, depending on stops and whether a cross-platform change at Hefei South is needed. Seating includes Second, First, and Business Class with assigned seats, power outlets, and trolley catering. By comparison, classic T/K/Z trains depart from Shanghai Railway Station toward Anhui at 120–160 km/h (75–99 mph). They usually involve a change at Hefei or Huainan for the last segment to Shouxian and take roughly 6–8 hours overall. These conventional trains offer Hard/Soft Seat and Hard/Soft Sleeper options, more intermediate stops, and basic onboard facilities. Choose G/D high-speed services for the shortest journey and modern amenities, or opt for classic services for lower fares or overnight-friendly schedules.
