All high-speed trains on the Shanghai to Shangrao route offer Second, First, and Business Class seating (Economy, Premium Economy, and First). The fastest G-series Fuxing services, typically running from Shanghai Hongqiao via Hangzhou East along the Shanghai–Hangzhou and Shanghai–Kunming high-speed corridors, operate at up to 300 km/h (186 mph) and complete the journey in about 2 hours 20 minutes to 2 hours 50 minutes, with fewer intermediate stops. In comparison, D-series high-speed trains (Hexie EMUs) on the same corridor run at up to 250 km/h (155 mph) and take roughly 3 hours 30 minutes to 4 hours, as they call at more stations such as Yiwu, Jinhua, Quzhou, and sometimes smaller regional stops. Onboard, G and D trains provide air-conditioned coaches, power outlets at seats, tray tables, overhead luggage racks, and clean restrooms, with a trolley or kiosk for snacks and drinks. Seating layouts differ by class: Second Class is 3+2 across, First Class is 2+2 with extra width, and Business Class is 1+2 with wider recline or lie-flat pods on select Fuxing sets. Digital seat indicators and clear bilingual announcements are standard. For the quickest end-to-end travel between Shanghai Hongqiao and Shangrao, choose a G-series high-speed train. Travelers prioritizing lower fares or access to additional regional stations can opt for a D-series service, accepting the longer runtime. Business Class suits those seeking maximum space, First Class offers a step up in comfort, and Second Class remains the best-value option for this corridor.
