A wagon (in British English, sometimes waggon) or dray is a heavy four-wheeled vehicle pulled by animals such as horses, mules or oxen, and used for transportation of people or goods. Wagons are distinguished from carts (which have two wheels), and from lighter four-wheeled vehicles such as carriages. A wagon may be pulled by one animal or by several, often in pairs. Sometimes, the word is also used for railroad cars (not motorized, for goods or passengers), and it's a part / the usual short form of station wagon, the non-British term for a sedan (saloon) with an extended rear cargo area. Other names: estate (car) / shooting brake (UK), break (F), station sedan (Aus), Kombi (generally in German language, in English also varied to combi), Variant (VW models), Caravan (GM's Opel models), Avant (Audi's wagons), Touring (BMW's wagons).
