The term captured the power, speed, and industrial novelty of the first trains, contrasting the mechanical 'horse' with the animal-powered transport it was replacing. This metaphor was particularly common in North America during the westward expansion and the construction of the first transcontinental railroad, which was completed in 1869.",
