Morphology

tank + engine

The meaning 'a steam locomotive that carries its own fuel and water' is directly derivable from combining 'tank' (a container for liquids) with 'engine' (a locomotive/machine), implying an engine that has tanks. This noun–noun compounding is a straightforward compositional pattern found cross-linguistically, so a B1 learner who knows both words would likely infer the intended meaning.

Etymology

Tank engine comes from the clear image of small water and fuel tanks fixed on or around the engine, so the locomotive carries its own supplies instead of hauling a separate car. So today tank engine means 'a locomotive that carries its own fuel and water'.
