All high-speed G-series trains on the Shanghai to Suqian route offer Second, First, and Business Class seating, with power outlets and a catering trolley. The fastest direct services typically use Fuxing CR400 trainsets, running from Shanghai Hongqiao to Suqian East over a 350 km/h (217 mph) segment between Shanghai and Nanjing, then continuing on a 250 km/h (155 mph) section across northern Jiangsu. End-to-end travel time is about 2 hours 40 minutes to 3 hours, with limited stops at major nodes such as Suzhou, Wuxi, Changzhou, and Nanjing South. In comparison, some departures are scheduled as D-series or as G services with more intermediate calls or a routing via the Shanghai–Suzhou–Nantong corridor. These trains are generally capped at 200–250 km/h (124–155 mph) and take roughly 3 hours 30 minutes to 4 hours, trading speed for broader regional coverage and additional time slots. Onboard, both G and D services provide air-conditioned carriages, clean restrooms, and seat-back tables; many Fuxing sets also offer Wi‑Fi. For a more premium experience, Business Class features lie-flat seats (1–2 layout), First Class (2–2) offers extra width and recline, while Second Class (3–2) delivers the best value for this route.
