On the Shanghai to Zigong route, travelers generally choose between a high‑speed combination and a direct overnight classic service. The fastest daytime option uses China Railway’s Fuxing G‑series high‑speed trains from Shanghai Hongqiao toward Sichuan, with a transfer (most commonly at Chengdu East, Chongqing West, or Neijiang North) for the final leg into Zigong. These G‑series trains run up to 300–350 km/h (186–217 mph) on core sections such as Shanghai–Nanjing–Hefei–Wuhan, then continue across mountainous stretches where speeds are typically 200–250 km/h (124–155 mph). Because there is currently no through high‑speed service directly into Zigong, the last segment is usually on a regional EMU (C/D) or a conventional train. Total travel time with a good connection is about 11–14 hours. Seating on high‑speed services includes Second, First, and Business Class, with power outlets and food trolleys. For a no‑transfer journey, classic overnight Z/T/K trains run from Shanghai to Zigong’s conventional station. These services cruise at around 120–160 km/h (75–99 mph) and take roughly 28–34 hours, depending on the timetable and path. They offer Hard/Soft Sleeper and Hard/Soft Seat, plus a dining car. In short: choose the Fuxing high‑speed plus transfer for the quickest overall time, or the direct sleeper for a single‑seat ride to central Zigong.
