There is no doubt that back when it was launched London’s underground was a huge revolution.
It was opened on the 10th of January 1863, although a few years earlier the Times newspaper described the invention as an “insult to common sense”. The wisdom of the project was called into question, especially the operation of a machine that ran underground driven by steam. However, the figures ended up showing that Charles Person, its visionary creator, was right: in its first year of operations, 11.8 million passengers used the celebrated Metropolitan Line, the underground’s pioneering line. At that time, the city had just 3.2 million inhabitants.
