Horse trouble

Late afternoon and another train of empty coal wagons is approaching Xiahua on the Huanan Coal Railway. The parallel road has a cart upon it pulled by a pair of horses who panicked as it was overtaken by the train and attempted to set off cross-country. The couple with the cart are seen here attempting to control their motive power before it escapes. I was surprised to see this as I would have expected the local horses to be well used to passing trains.
