London's Underground short history
In the middle of the 19th century, London was the largest city in the world with over 2,5 million inhabitants and an area over 100 square km.
The streets were narrow and almost constantly clogged by horse-drawn vehicles - basic way of transport in those years. The rail network was perfectly developed in its suburbia, but trains were unable to get into London.
