High-speed trains link Shanghai (primarily Shanghai Hongqiao) with Wanzhi South (Wanzhinan) in Anhui. Two service types operate on this corridor: faster G-series trains and slightly slower D-series trains. - G-series high-speed trains: Typically CR400 “Fuxing” or CRH380 sets. They run up to 300 km/h (186 mph) on the Shanghai–Nanjing Intercity segment and up to 250 km/h (155 mph) on the Nanjing–Anqing Intercity section that serves Wanzhi South. Fastest journeys take about 1 hour 50 minutes to 2 hours 15 minutes, depending on stops. Key intermediate stations often include Suzhou North, Wuxi East, Changzhou North, Nanjing South, and Wuhu. Seating options usually include Second Class, First Class, and Business Class, with power outlets, overhead luggage racks, and clean restrooms. - D-series high-speed trains: Commonly CRH2/CRH1 EMUs operating up to 250 km/h (155 mph) on most of the route. These services make more intermediate stops and generally take around 2 hours 20 minutes to 2 hours 50 minutes. Seating is typically Second and First Class, with similar onboard amenities. For the quickest trip, choose a direct G-series service with limited stops. Travelers prioritizing broader station coverage or off-peak fares may opt for D-series trains. Both options are high-speed services on this route and use modern EMU rolling stock.
