 A night element to the route was introduced on 27 November 1999, in the form of route N24, to replace part of the withdrawn route N2 between Hampstead Heath and Pimlico.The N prefix was dropped during April 2004, thus making it a 24-hour route.In February 2010 it was reported that a Muslim bus driver, new to the country, pulled his 24 bus over near Gospel Oak, locked the passengers in and prayed to Mecca.
