. "A coach is originally a large, usually closed, four-wheeled carriage with two or more horses harnessed as a team, controlled by a coachman and/or one or more postilions. It had doors in the sides, with generally a front and a back seat inside and, for the driver, a small, usually elevated seat in front called a box, box seat or coach box. The term \"coach\" first came into use in the 15th century, and spread across Europe."@en . . .
