Shanghai–Shenzhen–Hong Kong high-speed corridor

Roughly eight hours from Shanghai Hongqiao to West Kowloon, with no change of train.

Trains leave Shanghai Hongqiao and run south along the coast through Zhejiang and Fujian, joining the Hong Kong line at Shenzhen North. As on every service into West Kowloon, Hong Kong immigration is completed inside the station on arrival rather than at a land crossing.

• These trains use Shanghai Hongqiao, not Shanghai or Shanghai South — check which station your ticket names before setting off.
• If the direct train is sold out, Shenzhen North plus a short metro or shuttle across the border is the usual fallback.
