Iron horse

Origin

When steam locomotives first began to scorch their way across the countryside in the early 19th century, they were truly a sight to behold. These colossal machines, crafted from iron and steel, moved with an unprecedented power, pulling vast carriages without a single living beast. Observers, grappling with this revolutionary mode of transport, sought a familiar analogy. They saw the relentless, tireless strength and the pulling capability, much like a powerful draft horse, but encased in metal. Thus, the vivid image of the "iron horse" was born, a powerful metaphor that captured both the material reality and the astounding, mechanical might of these new titans of travel.
