On the Shanghai–Longyou route, travelers typically choose between direct conventional services (Z/T/K) on the Shanghai–Kunming Railway and a high-speed option using G-series trains to nearby hubs with a short connection into Longyou. Direct Z/T/K trains run at about 120–160 km/h (75–99 mph) and take roughly 5 to 6 hours, calling at key stations such as Hangzhou and Jinhua before reaching Longyou. High-speed G-series services (CRH380 or CR400 “Fuxing”) operate between Shanghai Hongqiao and Jinhua or Quzhou at 300–350 km/h (186–217 mph); combined with a brief regional hop to Longyou, end-to-end time is typically around 3 to 3.5 hours, depending on the transfer. Seating on G-series includes Second, First, and Business Class, while conventional trains offer Hard/Soft Seat and Soft Sleeper. G-series high-speed trains feature reserved seating, power outlets, and a trolley service, with limited stops such as Hangzhou East, Yiwu, and Jinhua/Quzhou, making them the fastest choice if a change is acceptable. Direct Z/T/K trains provide a single-seat ride to Longyou and more class variety but stop more often and run at lower average speeds. For the quickest journey, choose the high-speed segment plus local train; for a straightforward direct ride, the conventional services are suitable. First or Business Class on high-speed offers wider seats, while Soft Sleeper on conventional trains adds privacy.
