High-speed G-series trains run from Shanghai Hongqiao to Nanchang West on the Shanghai–Kunming High-Speed Railway, typically using Fuxing (CR400) and Hexie (CRH380) trainsets. Operating at up to 300–350 km/h (186–217 mph) on key sections, the fastest services complete the trip in about 3 hours 20 minutes, while most journeys take around 3.5–4 hours depending on stops at major stations such as Hangzhou East, Jinhua, and Shangrao. Seating options include Second, First, and Business Class, with power outlets, clean restrooms, and food trolleys available onboard. Conventional Z/T/K trains also connect Shanghai (often from Shanghai Main or Shanghai South) with Nanchang (Nanchang or Nanchang East), running at up to 120–160 km/h (75–99 mph) and taking roughly 9–11 hours due to more frequent stops. These services offer Hard Seat, Soft Seat (on select trains), and Hard/Soft Sleeper compartments, plus a dining car. For travelers prioritizing speed and modern amenities, the G-series high-speed option is the primary choice, while overnight sleepers provide a budget-friendly alternative with lie-flat berths.
