All high-speed G-series trains on the Shanghai to Heyuandong route offer a choice of Second, First, and Business Class seating, covering economy through premium options. The fastest services are limited-stop G trains running via Shanghai Hongqiao, Hangzhou East, Shangrao, and Ganzhou West before reaching Heyuandong, typically using CR400 “Fuxing” or CRH380 EMUs. These operate at 250–300 km/h (155–186 mph) and complete the journey in about 6.5 to 7.5 hours, depending on the stopping pattern. In comparison, other G-series itineraries involve a same-station transfer at Shangrao or Ganzhou West and include more intermediate stops, resulting in total travel times of roughly 7 to 9 hours. Both service patterns use modern high-speed stock with power outlets, spacious seating, and trolley or dining options; Business Class provides lie‑flat seating, while First Class offers wider 2+2 seats. Travelers prioritizing the quickest arrival should look for limited-stop direct G trains, while those seeking more departure choices may opt for a transfer-based schedule.
