The first underground was built in London, which was the biggest and most
overcrowded city of the world in the mid 19th century.
And also it was rich enough, people could afford the fee to repay the
investment.
And as a matter of fact the railway and the construction of deep tunnels was
both developed in London.
The next underground which was built was in Budapest, Hungary, the first
underground on the continent.
And now the underground fever started in the big cities, and one after the other
built its own system.
Today 162 cities have rapid transit systems, totalling more than 8,000km of
track and 7,000 stations.
