Between 1958 and 1968, variant London bus route 242A ran between Upshire and Potters Bar.
In the 1990s, route 242 was handed to Metroline as a commercial operation, thereby removing it from the Transport for London network.[3] The section between Waltham Cross and Chingford station via Waltham Abbey was also withdrawn.
Today, the original route 242 is operated commercially as a non-TfL route between Waltham Cross and Potters Bar by Metroline and Central Connect, with a reduced service.
In 2004 it became a 24-hour service with night bus route N242 services that followed the same route renumbered 242.[8] The route of the bus was criticised by London Assembly members for its use of narrow streets.[4][9]
In 2017, the route was diverted to terminate at St Paul's, before being cut back on 15 June 2019 to Aldgate bus station with a service frequency reduction.[10] The diversion to Aldgate was criticised for the reduction in access to the City of London and St Bartholomew's Hospital for residents.[11][12] The reduction in service frequency was criticised for its impacts on the deprived Clapton Park Estate, an area only served by the route.[13][14]
The night route continues to serve Tottenham Court Road station, and from 15 June 2019 was renumbered route N242.[15]
Upon being re-tendered in 2002, 2009 and 2016, the route was retained by Arriva London.[16][17]
