Typical of the crap coal they use there.
It looks like an awfully inefficient use of coal for their fuel.
Steam locomotives are not all that "efficient" anyway, and when crap coal is used, that can happen.
Is this by design, is something not set up right in the engine, or are they just putting on a show for the camera ?
That, and other open pit coal mining operations in China, have exhibited the same "show" from their steam locomotives at night for some years. They are NOT "putting on a show for the camera".
