On the Shanghai to Fangcheng route, the quickest option is a high-speed combination: Fuxing G‑series trains from Shanghai Hongqiao to Nanning East, then a D‑series intercity EMU to Fangchenggang (Fangcheng). G‑trains run up to 300 km/h (186 mph) on the main corridors via Hangzhou, Nanchang, Changsha, and Guilin, while the Nanning–Fangcheng section typically operates at 200–250 km/h (124–155 mph). With a single same‑station transfer at Nanning East, total journey time is usually about 11–13 hours. High‑speed services offer Second, First, and Business Class seating, power outlets, and frequent departures, with the G‑segment making limited stops for faster end‑to‑end times. By comparison, conventional long‑distance services (Z/T/K series) run from Shanghai—often from Shanghai South—toward Guangxi and onward to Fangcheng/Fangchenggang, with operating speeds around 120–160 km/h (75–99 mph). These trains make more intermediate stops and take roughly 20–24 hours in total. They offer Hard/Soft Seat and Hard/Soft Sleeper options, suiting travelers who prefer an overnight berth and lower base fares over speed.
