High-speed trains on the Shanghai to Deqing route are mainly G-series services operated by Fuxing EMUs, with some D-series Hexie EMUs also appearing at peak times. Most high-speed departures use Shanghai Hongqiao and run to Deqing (Zhejiang) via the regional high-speed corridors around Hangzhou/Huzhou. G-series services reach 250–300 km/h (155–186 mph) and typically cover the journey in about 40–60 minutes with limited stops. D-series trains operate at 200–250 km/h (124–155 mph) and take roughly 55–80 minutes due to additional intermediate calls. Conventional K/T services on the legacy line depart from Shanghai (main) station at 120–160 km/h (75–99 mph) and usually take around 2–3 hours. Onboard, G/D high-speed trains offer Second, First, and Business Class seating, air-conditioning, power outlets, and trolley service for drinks and snacks. Business Class features wider seats in a 1–2 layout with deep recline, while First and Second Class provide reserved seating with ample legroom. Conventional K/T trains offer Hard/Soft Seat (and occasionally Soft Sleeper on through services), basic catering options, and more frequent intermediate stops. For the quickest arrival, choose a G-series high-speed train; D-series offers a balance of speed and extra station coverage; legacy K/T trains suit travelers prioritizing lower fares or late departures.
