High-speed trains on the Shanghai to Tongchengnan route offer Second, First, and Business Class seating, with Business providing lie-flat seats and extra space. The fastest services are G-series Fuxing trains, running up to 350 km/h (217 mp/h) on the Shanghai–Nanjing high-speed segment, then continuing around 250 km/h (155 mp/h) between Nanjing/Hefei and Tongchengnan. Typical journeys start at Shanghai Hongqiao and stop at major hubs such as Nanjing South and Hefei South before reaching Tongchengnan. End-to-end travel time is about 3 hours 30 minutes on the quickest runs, depending on intermediate stops. In comparison, selected D-series CRH trains also operate on this corridor at up to 250 km/h (155 mp/h), making more intermediate stops and taking roughly 4 to 4 hours 30 minutes. Both service types provide power outlets and luggage racks, but the G-series is the better choice for minimizing travel time, while the D-series suits travelers aiming for more regional station access along the Shanghai–Nanjing–Hefei corridor.
