On the Shanghai to Linfen route, the quickest daytime option combines China Railway high-speed services. G-series Fuxing trains run from Shanghai Hongqiao toward Xi’an North via key hubs such as Nanjing South, Xuzhou East, and Zhengzhou East, on sections rated at 300–350 km/h (186–217 mph). From Xi’an North, D-series trains on the Datong–Xi’an high-speed line continue to Linfen West at up to 250 km/h (155 mph). Seating on these services includes Second Class, First Class, and Business Class. With a single connection—most commonly at Xi’an North—the overall journey typically takes about 7.5–9 hours, depending on the specific pairing of G and D trains and the number of intermediate stops. For a one-seat ride, conventional overnight trains (T/K category) operate from Shanghai Railway Station to Linfen (central station). These run on the classic network at up to 120–160 km/h (75–99 mph), make more stops, and take roughly 16–20 hours. They offer Hard Seat, Hard Sleeper, and Soft Sleeper classes, a dining car, and hot-water dispensers. Travelers prioritizing the shortest travel time generally choose the high-speed combination via Xi’an North, while the overnight sleeper provides a direct, budget-friendly night run.
