High-speed trains on the Shanghai to Huaiandong (Huai’an East) route offer Second Class, First Class, and on many departures Business Class seating, giving travelers a clear choice of comfort levels. The fastest option is a direct G-series Fuxing service, running up to 350 km/h (217 mp/h) between Shanghai Hongqiao and Nanjing South before continuing on tracks limited to about 250 km/h (155 mp/h) toward Huai’an East. End-to-end times are typically around 2 hours 20 minutes to 2 hours 50 minutes, with limited stops along the way, most notably at Nanjing South. Alternative services include D-series high-speed trains or G-series journeys that require a same-station change at Nanjing South; these make more intermediate stops and operate at about 200–250 km/h (124–155 mp/h), bringing total travel time to roughly 3–3.5 hours. Onboard you’ll find air-conditioned coaches, power outlets, and trolley or kiosk refreshments; First Class adds wider seating, while Business Class (where available) provides a 1–2 layout with recliner or lie-flat seats. Choose a direct G-series for the shortest time, or opt for D-series/transfer services for broader station coverage and lower fares.
