Brian sent me this excellent link to a Chinese narrow gauge coal line. The trains are on their last legs and the tracklaying is even worse! No doubt now long gone. However, the surroundings are a charming mix of the rural and industrial.
There’s no shortage of Chinese steam to look at on YouTube, including this one.
Try modelling that!
Nearer to home, this old locomotive shed converted into a wagon works looks a good basis for a model.
