All high-speed trains on the Shanghai to Quanzhou route offer reserved seating, with G-series services providing Second, First, and Business Class (lie-flat) options. The fastest trains are G-series Fuxing services (CR400/CRH380), running via the Shanghai–Hangzhou high-speed corridor before continuing down the southeast coast. These reach 300–350 km/h (186–217 mph) on the fastest segments, but coastal sections toward Wenzhou, Fuzhou, and Quanzhou are usually limited to about 200–250 km/h (124–155 mph). End-to-end, limited-stop G trains typically take around 5 hours 30 minutes to 6 hours 30 minutes, with key calls such as Hangzhou East, Wenzhou South, and Fuzhou. D-series EMU trains (Hexie) also operate on this corridor, generally running at 200–250 km/h (124–155 mph) with more intermediate stops, resulting in journey times of roughly 7 hours 30 minutes to 9 hours. Some D services are overnight and include soft-sleeper berths, while daytime sets offer Second and First Class seating. Onboard across both types you’ll find assigned seats, power outlets, and trolley or dining service; choose G-series for the shortest schedules, or D-series for broader stop coverage and sleeper options.
