These minutes are both related to underground trains!
The world’s first underground railway was created in London in 1863 and was called the Metropolitan Railway.
These trains looked very different to the modern London tube: the carriages were made of wood and they were pulled by steam-locomotives! Around 30 years later the underground trains became electrified.
During World War Two, most underground platforms in London were used as air raid shelters. This was because it was much safer to be underground when German air attacks started. Other underground platforms were used to keep museum treasures safe from the air raids, such as on the Piccadilly line.
Today, the London underground has 1.37 billion passengers every year!
