High-speed trains link Shanghai and Hangzhou throughout the day, mainly between Shanghai Hongqiao and Hangzhou East. The fastest G-category services are operated by Fuxing sets (CR400 series) and some Hexie sets (CRH380 series), offering Second, First, and Business Class. On this corridor they run at up to 300 km/h (186 mph) and complete the trip in about 45–55 minutes with limited stops; other G services that call at key stations such as Jiaxing South and Haining West typically take 55–70 minutes. In comparison, D-category Hexie trains (CRH series) operate at 200–250 km/h (124–155 mph), usually take 1 hour 15 minutes to 1 hour 45 minutes, and make more intermediate stops. D trains often provide Second and First Class seating only and may use Shanghai Station or Hangzhou Station in addition to the high-speed terminals. Fuxing G-trains include features such as power outlets at seats, generous luggage space, clean restrooms, and a trolley service; Business Class offers wider seats with a lie-flat option, while D trains provide simpler interiors without Business Class. For the shortest journey time, choose a G service; D trains suit travelers prioritizing lower fares or direct access to certain city-center stations.
