High-speed G-series Fuxing trains (CR400AF/BF) link Shanghai Hongqiao with Beijing South at 300–350 km/h (186–217 mph). The fastest runs take about 4 hours 18 minutes to 4 hours 40 minutes with limited stops such as Nanjing South and Jinan West. To continue to Zhoukoudong, transfer in Beijing—HSR arrives at Beijing South, while the onward suburban/regular segment to Zhoukoudong operates on conventional tracks at around 80–120 km/h (50–75 mph) and adds roughly 60–90 minutes depending on the connection. G-series offer Second, First, and Business Class seating, with power outlets and trolley catering. Conventional long-distance services (Z/T/K) also run from Shanghai to Beijing Railway Station at 120–160 km/h (75–99 mph), typically taking 11–13 hours, often scheduled overnight. From central Beijing, a regional train completes the final leg to Zhoukoudong on the same non–high-speed corridor. These trains provide seat and sleeper options (Hard/Soft Seat, Hard/Soft Sleeper). Choose the G-series for the quickest end-to-end time to Zhoukoudong, while Z/T/K services suit travelers looking for an overnight ride and lower fares.
