This is a really nice Q&A from Logistics Management on China intermodal rail capacity:

Q: My company plans to set up a new distribution center in China to integrate the supply chain, and good intermodal rail access is essential for us to keep costs down. Which Chinese cities have strong intermodal rail capacity?

A: China is building up 18 modern intermodal terminals capable of handling 0.5 million to 1million TEU per year. They are:

Coastal: Dalian, Tianjin, Qingdao, Shanghai, Ningbo, Shenzhen, and Guangzhou.

Inland: Shenyang, Harbin, Beijing, Zhengzhou, Jinan, Wuhan, Chengdu, Kunming, Xian, Lanzhou, and Urumqi.

These cities are strong candidates for DC's that need strong intermodal rail capacity.
