The carriage in Fable II is a way to fast travel from Oakfield, Westcliff, and Bowerstone Market to each other. In order to use the carriage, you must pay a fee for each ride. The upside to you using a carriage ride is that it is faster than your standard fast-travel or traveling on foot. The counterpart to the carriage is the ship which can be used to get to Westcliff or Bloodstone from each other.
