What Fuel Does a Real Luke like Engine Use?

Those are fantastic photos Tramp and gives me a view of how tiny this model really is. Its almost as if they are from one of these Quarter size railroad ride attractions. The hoppers look more like container buckets and must only use a small amount with the size of a shovel that would fit in that opening. Thank you Tramp for the info.

I just figured he was a non fueled engine because he had no coal bunker/tender, and he uses a steam accumulator that gets periodically refilled. Or perhaps no steam at all and ran on compressed air. Since he is a shunting/switching engine, he really wouldn't go very far to need a coal/firebox setup. Learn something new everyday!

But here is a picture of a non fueled engine in the us:
