High-speed trains on the Shanghai to Huaibeibei route are operated by China Railway High-speed (CRH), with most departures using G-series Fuxing services and some D-series runs. G-series Fuxing sets (CR400AF/BF and select CRH380 variants) reach up to 300–350 km/h (186–217 mph) on the fastest sections, notably the Shanghai–Nanjing Intercity and parts of the Shangqiu–Hefei–Hangzhou high-speed corridor. Due to varying line limits inland, speeds can drop to 250–300 km/h (155–186 mph). Typical end-to-end travel time is about 3.5–4.5 hours, often with a single change at hubs such as Hefei South, Bengbu South, Suzhou (Anhui), or Bozhou; direct G-series departures may be limited on some days. D-series high-speed trains (CRH2/CRH3) run the same corridor at lower top speeds of 200–250 km/h (124–155 mph) and make more intermediate stops, resulting in journeys of roughly 4.5–6 hours. These trains are a solid choice when G-series times do not fit, though they are slower on the Shanghai–Nanjing and Anhui segments. For seating, G-series trains offer Second Class, First Class, and Business Class, with wide seats, power outlets, and trolley service; D-series typically provide Second and First Class with similar onboard facilities. High-speed departures mainly use Shanghai Hongqiao, arriving at Huaibeibei (the city’s high-speed station). Conventional Z/K services from Shanghai (main station) run to Huaibei (not Huaibeibei) at 120–160 km/h (75–99 mph) and take about 8–10 hours, serving as an overnight or budget alternative.
