Morphology

iron + horse

The compound uses a transparent metaphorical logic: 'iron' + 'horse' suggests a horse made of iron or a machine that replaces a horse, so learners can infer a non-literal, mechanical referent. However, identifying the specific referent 'locomotive' (a nineteenth-century train engine) requires cultural/historical knowledge and is not fully predictable from the parts alone, so it is only partially transparent to a B1 learner.

Etymology

Iron horse comes from the early days of steam trains, when people saw a big metal engine made of iron that pulled carriages like a horse. So the phrase came to mean 'a train'.
