On the Shanghai to Ningde route, the fastest options are D-series high-speed trains running on the coastal corridor, typically using Shanghai Hongqiao and calling at major hubs such as Hangzhou East, Ningbo, Wenzhou South, and Fuding/Xiapu before reaching Ningde. These CRH EMUs operate at 200–250 km/h (124–155 mph) and usually complete the journey in about 5.5 to 6.5 hours, with Second Class and First Class seating, air-conditioning, power outlets, and a trolley service for drinks and snacks. By comparison, slower conventional services (Z/T/K) on the same corridor use older rolling stock and lower line speeds of around 120–160 km/h (75–99 mph), stretching travel time to roughly 9–11 hours while offering seat and sleeper options (hard/soft seat, hard/soft sleeper). There are currently no direct 350 km/h (217 mph) G-series services to Ningde; the coastal Wenzhou–Fuzhou line that serves Ningde is engineered for up to 250 km/h (155 mph). Travelers prioritizing speed should choose the D-series high-speed trains, while those seeking overnight sleeper accommodation can opt for the conventional services.
