On the Shanghai to Qingdao route, the fastest option is the G-series Fuxing high-speed train (typically CR400AF/BF). These trains run at up to 350 km/h (217 mph) on the Beijing–Shanghai High-Speed Railway segment and around 300–350 km/h (186–217 mph) between Jinan and Qingdao, completing the trip in about 4 to 4.5 hours depending on stops. Most services start from Shanghai Hongqiao and arrive at Qingdao or Qingdao North, with limited calls at major stations such as Nanjing South, Xuzhou East, Jinan (West/East), Zibo North, and Weifang North. Seating classes include Second Class (3+2), First Class (2+2), and Business Class with lie-flat seats, plus power outlets and a trolley or café bar for refreshments. D-series high-speed trains (often CRH2/CRH5) also connect Shanghai and Qingdao, running at 200–250 km/h (124–155 mph). They make more intermediate stops and usually take about 5.5 to 7 hours. D trains generally offer Second and First Class seating, with similar onboard amenities but fewer premium features than the G-series. Travelers prioritizing the shortest journey time on this corridor typically choose the G-series, while D-series services provide broader station coverage at a lower speed.
