Depends how much it is going and how fast it is going.
A train that runs on steam. But first you need the coal and fire and shovel.
The farther they went, the more water they needed.
Well, it needs energy from somewhere, something to turn water into steam. Can be coal, can be firewood, etc.
steam is water
None if you steam them
Coal or wood
The train may need water , coal , pick-up/drop off passengers/cargo , a track obstruction .
You need to cool it down.
Water is needed for distillation to control the amount of alcohol and to produce steam. Much of the water is boiled off during the process but the remaining percentage dictates the proof.
Steam heat normal Hot water perhaps air in lines and need to be purged
Steam engines do not need to be built next to rivers or streams.
Steam power could be described as pressure. Water heated above the boiling point turns to steam and the molecules move very rapidly and want to separate. If the water is in an enclosed area, the pressure will increase. This pressure can be used to move components of an engine that generates electricity. Generally, steam power is used to generate electricity or in the case of old railroad engines, it was used to actually push the train forward. Generally steam power isn't very efficient because you need an extreme source of heat to bring the water to boiling.
