Since the mid-1940s, London began to resell its buses after they were no
longer suitable for service in the capital. Bus and coach operators both
big and small would snap up these buses and use them for further
service. Perhaps the most noticeable cascade of former London Buses was
of the AEC Routemaster during the 1980s, which were bought en mass by
provincial operators around the country. The continual investment of new
buses in London in the early 2000s saw the displacement of many of the
early low-floor buses to provincial operators. Changes to emission
standards led to the withdrawal of further low-floor buses from the
capital, benefiting the independent operators around the country. London
Low-Floor Buses in Exile showcases the numerous liveries and operators
of former London low-floor buses around the United Kingdom and the
Republic of Ireland between 2000 and 2021.
