Etymology: "Railbuses" is the plural of "railbus," and the word is a plain compound of "rail" and "bus." The "bus" half is short for "omnibus," a Latin-derived term ("omnibus," meaning "for all") that was adopted in the 1820s for public horse-drawn carriages, then clipped to "bus" in the 1830s. The "rail" half is the older and more familiar element, referring to the iron or steel tracks that guide a train. Combining the two produced a name for a vehicle that runs on tracks but carries passengers in the manner of a bus, typically a small, light unit rather than a full locomotive pulling carriages. The word thus describes a hybrid: a railway vehicle built on the logic of road transport. Because the coinage is a transparent compound, its meaning can be read directly from its parts.

Synonyms: rail vehicles, commuter trains
