What Fuel Does a Real Luke like Engine Use?

[Super]

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.

On another note, the Plarail version of Luke resembles more the narrow gauge of this type engine whereas the Trackmaster version has better detailing with all the rivets showing.
