Take train on 72-Hour Visa-free Transit

Hello,
I have flight from Bangkok to Wuhan and 3 days later another flight from Wuhan to Viet-nam. I will use 72-Hour Visa-free Transit.

However, During my trip in China, I need to go to Jingzhou (1h train far from Wuhan). Am I authorized to take train? Do train officer check visa before taking train?
