A stagecoach is a type of four-wheeled enclosed passenger and/or mailcoach, strongly sprung and drawn by four horses, widely used before the introduction of railway transport. A stagecoach would stop periodically at staging posts to take on fresh horses. They were also convenient places to exchange mail, and to allow the passengers and crew food and rest breaks.
The stagecoach, with seats outside and in, was a public conveyance which was known in England from the 16th century. Until the railway systems of Europe drove the stagecoaches out of business they had regular routes (stages) all over Britain and the Continent. In Britain their carrying the mails from 1784 generated the term "mail coach."
Today the most familiar image of the stagecoach is that seen in film Westerns, but they were also used throughout eastern North America and Europe. The diligence, though not invariably with four horses, was the Continental analogue for public conveyance, with other minor varieties such as the Stellwagen and Eilwagen. Stagecoaches could compete with canal boats, but they were rendered obsolete as the rail network expanded.
A constant danger for stagecoach travellers was the threat of robbery by highwaymen or bandits.

To many people the idea of stagecoach transportation might seem to have been a peaceful, easy-going method of conveyance but in reality it was a swaggering, rakish, hurried race to complete the journey as quickly as possible.
Stagecoaches worked over a series of short stages between local towns and villages and within each village horses would be stood or stabled in readiness to replace those of an incoming coach.
The other coaching house in Ferrybridge was the Greyhound whose stables could accommodate fifty horses although both the stabling and coach houses as well as the tap for use by the post boys and horse keepers were across the road.
