The Railways
Many countries have a network of railways to help transport different types
of products. The earliest system was in Ancient Greece in 600 BC. Later
rail inks were built to connect short distances. In the 19th century, this
changed very much. Many countries developed their own network. They
had private links between different towns with Germany and Britain.
Britain had the best links. These links allowed carrying heavy goods such
as coal, iron, ore, and wood. Building a railway was a hard work for
labourers. Railways are very expensive to construct but important to
transport raw materials and such goods as textiles quickly and cheaply.
In the early 19th century, the first passengers travelled on the railways with
horse-drawn carriages. From 1840-1850 Britain was connected by railways
and used steam engine to pull carriages.
1. The Ancient Greeks had a railway system in 800BC.
2. The very early railways connected a lot of cities.
3. British passengers first travelled on trains in the 1820s.
4. 'No-frills' airlines are popular because they are costly.
