either of two types of vehicle. One is a heavy four-wheeled carriage frame used for the training and exercising of horses, either singly or in teams of two or four. It has no body parts except for a high seat upon which the driver sits and a small platform for a helper immediately behind.

The other is a team-drawn conveyance of the heavy phaeton type that is used for pleasure excursions by six or more people. It is a four-wheeled, straight-bodied, open carriage, usually with no doors or side pieces in front of the seats.
