If those stations are serious about the purported 200kg limit, the bucket on your JH600B will push you way over the permitted weight. That's got to add 40kg or more to a bike that already tips the scales at just under 200kg.

Best to follow Milton's advice and ride Chongqing-Jiuquan, but if you do manage to get it on the train, a lot of folks will be wanting to read details.

The Black Bats, a Changjiang club in Shanghai, seems always to be shipping their sidecar bikes by truck, not train. If you'd like to contact them, let me know.

cheers!
