Three tiers, three use cases
G-train (300-350 km/h) is the default for long inter-city legs. D-train (200-250 km/h) connects secondary cities and runs older lines. C-train (intercity 200 km/h) is for short metro-region connections like Beijing-Tianjin. For tourist routes the choice is almost always G, with very occasional D for legs G doesn't serve.
G-train (高铁 Gao-tie). 300-350 km/h top speed. Beijing-Shanghai 4-4.5 hours. Beijing-Xi'an 4.5 hours. Shanghai-Wuhan 4.5 hours. Modern CRH380 and Fuxing CR400 sets. Three classes: Second class (二等座, 2+3 seating), First class (一等座, 2+2 seating), Business class (商务座, 1+2 reclining). On our routes: business class default for journeys 3+ hours, first class for shorter.
D-train (动车 Dong-che). 200-250 km/h. Older lines and routes G doesn't yet serve. CRH1, CRH2 sets. Most have second class and first class only — no business class on older D-train sets. Used for some Yunnan, Sichuan, and northwest connections.
C-train (城际 Cheng-ji). Intercity short-distance metro-region. Beijing-Tianjin 35 minutes. Frequent service like a metro. Mostly second class. Rarely the right tool for tourist routes.
