Surface Forms

foamer singular

foamers plural

Morphology

foamer = foam (semi-transparent) = foam + er

The device meaning is fully compositional as 'one that produces foam', but the train-enthusiast slang sense is a metaphorical extension and less predictable.

Etymology

Foamer comes from foam plus -er, so it can mean 'a machine that makes foam' used in cleaning. A helpful way to remember the railfan use is the image of someone 'foaming at the mouth' with excitement, so a foamer is an extremely enthusiastic train fan.
