Travelling in England Before Railways
There were no railways in England before 1825, and if people wanted to travel, they had to go by road, either on foot, on horseback, or in a coach. In the days before the railways, however, people did not travel as much as they do now. The roads were few, and most of them were bad, especially when it rained.
A journey by coach took a long time. Two hundred years ago passengers from Edinburgh to London were two weeks on the road – if the weather was good. A hundred years later, however, the journey was often done in about two days, and today the “Flying Scotsman” can take you from London to the capital of Scotland in about eight hours. Today many people
prefer to go to Edinburgh by air.
People could not travel much in the past as the fares were high. A coach could not take many people, and the fares were high because the coach-owners had to pay for the use of the horses that were kept at the inns (hotels) all along the road. Travelling in the mail coaches cost still more,
because they carried the mail and did not travel so slowly.
Even walking cost money in those days. On every highway (main road) and also on many of the side roads, there were gates called tollgates. When a traveller came to one, he had to pay a toll. This money was used to make the roads better.
But the greatest danger on the road two hundred years ago were the highwaymen. A highwayman was a man who took money and jewels from
travellers on the roads. Highwaymen stopped coaches and cried: “Your money or your life!” and passengers had to give them all they had. Sometimes a highwayman had friends at the inns. If some rich people stayed at an inn, the highwayman was soon told and he then stopped their carriage the next day.
That’s why travelling in the days of the coaches was dangerous and not very comfortable.-
