Wood or Coal Consumption

From: Alice_Friedemann@apl.com

... I'd like to know more about how much wood and coal it took to operate steam trains (and ships).
Did we ever reach a point where wood wasn't available?
How much cargo could be pulled by a steam train burning x amount of wood or coal for how many miles?

And now – what are the same figures for diesel engines?

I work for a large shipping company, so I have some idea of what it takes to run ships, but I don't know much about trains and the old steam ships.
