Definitions

Etymology: "Railbus" is a plain compound, built from "rail" and "bus," and its history is simple. The first part, "rail," refers to the metal track that guides a train, while "bus" is a shortened form of "omnibus," the large vehicle carrying many passengers. Put together, the name describes a bus that runs on rails rather than on roads. The idea behind the vehicle is the same as its name suggests: a light, self-propelled unit that carries passengers over short distances along a railway line. Because it is small, it can serve quiet branch lines or stops where a full-sized train would be too costly to run.

Synonyms: light rail vehicle, railcar, train bus, rail transport vehicle, commuter rail
