Coal was a unlimited resource that great Britain obtained and used to fuel the steam engine, trains, boats and tractors. Through coal the iron industry made. Coke was taken from coal and used to burn away impurities in crude iron. This made they iron of much high quality. This iron was used to build new machines and especially trains.
