Question

why did public transport become necessary in England by 20th century

Answer 1

Buses play a major role in the public transport of the United Kingdom, as well as seeing extensive private use. While rail transport has increased over the past twenty years due to road congestion, the same does not apply to buses, which have generally been used less, apart from in London where their use has increased significantly. Bus transport is heavily subsidized, especially in London[citation needed]. In 2014/15, there were 5.2 billion bus journeys in the UK, 2.4 billion of which were in London.
