What does railcar mean?
Railcar is a railway term for a vehicle designed to run on tracks. In American English, it most often means a railroad car, particularly a passenger coach, although the word is less common than “railroad car” in general. In British English, railcar can more specifically suggest a self-propelled passenger unit, such as a diesel multiple unit, in which the motive power and the passenger accommodation are combined in a single train vehicle. The word is practical and broadly technical, appearing in transport, manufacturing, railway operations, and news reporting about services and rolling stock. Its history also reflects the development of rail transport: railcar is a straightforward compound of “rail” and “car,” joining the idea of a trackway with a wheeled conveyance. The term is useful because it can name either an individual railway vehicle or, in specialized British usage, a self-contained train without suggesting a locomotive-hauled consist.

Where does railcar come from?
Railcar is a compound formed in the 19th century from English “rail” and “car,” both of which were already established words. “Car” comes through French from Latin carrus, while “rail” entered English from Old French and is related to Latin regula. The same components and related forms produced words such as railway, railroad, and carriage.
