On the Shanghai to Xiaogan route, the fastest option is the G‑category high‑speed service operated by China Railway (CRH/Fuxing). Typical itineraries run from Shanghai Hongqiao to Wuhan, then continue on the Wuhan–Xiaogan intercity line to Xiaogan East. Trains use CR400 Fuxing or CRH380A sets, reaching up to 300–350 km/h (186–217 mph) on the Shanghai–Nanjing section, around 250 km/h (155 mph) between Nanjing and Wuhan, and about 200–250 km/h (124–155 mph) from Wuhan to Xiaogan East. With a well‑timed transfer at Wuhan or Hankou, total travel time is about 4 h 45 m to 5 h 30 m; direct high‑speed runs to Xiaogan East are limited.
In comparison, classic Z/K services run from Shanghai (main station) to Xiaogan (central station) on the conventional Jingguang corridor. These trains top out at roughly 120–160 km/h (75–99 mph) and take around 10–13 hours. They are slower but provide a through ride without changing in Wuhan.
High‑speed G trains offer Second, First, and Business Class seating, reserved seats, air‑conditioning, power outlets, and a trolley or dining counter. Z/K trains provide hard/soft seats and hard/soft sleeper berths, with older rolling stock and a dining car on most departures.
