All high-speed services on the Shanghai to Shaoshan route use a change at Changsha South and offer reserved seating. The fastest option pairs a G-series Fuxing high-speed train (often CR400) from Shanghai Hongqiao to Changsha South at 300–350 km/h (186–217 mph), followed by a C-series intercity (typically CRH6) to Shaoshan South at up to 200 km/h (124 mph). This combination usually takes about 4 hours 45 minutes to 5 hours 30 minutes end-to-end, with the G service making limited stops such as Hangzhou East and Nanchang West. Seating on the G leg includes Second, First, and on some departures Business Class, while the C intercity segment generally offers First and Second Class. A slower alternative uses D-series high-speed trains between Shanghai and Changsha at 200–250 km/h (124–155 mph), with more intermediate stops along the Shanghai–Kunming corridor. This pushes the first leg to around 6–7.5 hours, and about 7–8.5 hours overall once the C-series hop to Shaoshan South is added. Across G/D/C services you can expect assigned seats, power outlets, and luggage racks; premium classes on the G segment provide wider seats and extra space.
