At about 30 seconds in, you can see a crank on the base of the narrow-gauge locomotive that's being moved by every revolution of the wheels. It sounds like it's controlling the whistle, blowing it a little every time the valve opens. Is that what's going on?
The crank to which you refer operates the valve gear of the loco, i.e. the flow of steam to and from the cylinders, and this is why the puffs of steam from the loco coincide with the crank movements. The (warning)whistle is completely seperate, and is controlled directly by the driver/fireman.
Actually it looks like I mistyped a bit there... What I am wondering about is the white-painted crank right at the base of the steam dome, top of the boiler, right below the whistle itself - not down by the rest of the valve gear. It can be seen from seconds 30-40 of the clip. That crank, whatever it is, seems to be linked into the valve gear...
Since the lever's so close to the whistle, and because there's that harsh squeaking noise with every revolution of the wheels, I thought it might be the whistle valve. I'd been looking at videos of Chinese C2 class narrow-gauge engines before I saw your clip, and the whistles do have kind of a harsh squeaky sound to them. But I guess the lever is more likely attached to a mechanical lubricator.
Anyway, thanks for the response! And the video is awesome.

I'll take the global warming if only these wonderful beasts were back on the rails. Internal combustion engines are boring. Steam engines are full of life.
The combustion of coal produces sulphur dioxide which has been linked to the reflection of sun rays before entering the earths atmosphere and actually cooling the planet. Sure, we'll be choking in the atmosphere, but its nonsense that coal is to blame for global warming. After all, it's odd that the noted increases in temperature have come in the 30 or so years after oil has taken over coal as a common energy source in many countries...
I love the face of the smiling Chinese man at .40!

Hope this is helpful.

maybe it isn't even a lever at all??? is it just some white thing hanging there and swinging around??
