The fastest high-speed services on the Shanghai to Liaoyang route are G-series trains (Fuxing), offering Second, First, and Business Class seating. The quickest itineraries run via key interchange stations such as Beijing South and Shenyang/Shenyang South, using 350 km/h (217 mph) sections on the Beijing–Shanghai and Beijing–Shenyang lines, then up to 300 km/h (186 mph) between Shenyang and Liaoyang on the Harbin–Dalian high-speed line; end-to-end times are typically about 7.5–9 hours with one or two changes. By comparison, D-series high-speed trains (CRH) operate at up to 250 km/h (155 mph) on parts of the corridor and can provide through daytime or overnight options, but overall journeys usually take 11–14 hours. Both G- and D-series services include reserved seating, air conditioning, power outlets, and a trolley or dining car service, while G-series sets often add Wi‑Fi and Business Class with lie-flat seats on select CR400 units. Conventional overnight Z/T trains run the same route at 120–160 km/h (75–99 mph) with soft- and hard-sleeper berths, appealing to travelers prioritizing lower fares or a night onboard over the shortest travel time.
