High-speed G-series trains—primarily Fuxing (CR400AF/CF) and Hexie (CRH380A) EMUs—operate the Shanghai Hongqiao to Xiamen corridor with Second, First, and Business Class seating. The fastest G services reach up to 350 km/h (217 mph) on the Shanghai–Hangzhou section, then run at 200–250 km/h (124–155 mph) along the coastal lines via Ningbo, Wenzhou, and Fuzhou. End-to-end times are typically about 5 hours 15 minutes to 6 hours, with limited-stop patterns calling at major stations such as Hangzhou East, Ningbo, Wenzhou South, Fuzhou, and Xiamen North. By comparison, D-series EMU services cover the same route at 200–250 km/h (124–155 mph) with more intermediate stops, taking roughly 8–10 hours. These trains offer Second and First Class seats, and some overnight schedules use sleeper-EMU sets with berths. Both G and D trains provide air-conditioning, power outlets, and trolley or dining-car catering, while G-series Business Class adds wider recliners and a quieter cabin for a more premium ride.
