On the Shanghai to Luzhou route, the quickest option uses China’s high-speed network. G-series Fuxing services run from Shanghai Hongqiao toward Chongqing West, reaching up to 300 km/h (186 mph) on flatter sections between Shanghai, Nanjing South, Hefei South, and Wuhan, with speeds reduced to around 200–250 km/h (124–155 mph) through the mountain corridors further west. From Chongqing West, D- or C-series EMUs continue to Luzhou on the regional high-speed line at up to 200–250 km/h (124–155 mph). With a single change in Chongqing, the end-to-end journey typically takes about 11–14 hours. High-speed trains offer Second, First, and Business Class (on many G services), power outlets, and trolley or dining-car service. In contrast, classic Z/T/K overnight trains on this corridor run at lower top speeds of about 120–160 km/h (75–99 mph) and can take roughly 28–32 hours, depending on routing and stops. These conventional services provide seat cars plus Hard and Soft Sleeper berths, suiting travelers prioritizing an overnight ride and lower fares over speed.
