The Overground forms part of the United Kingdom's National Rail network but it is under the concession control and branding of Transport for London (TfL). Operation has been contracted to Arriva Rail London since 2016. TfL previously assigned orange as a mode-specific colour for the Overground in branding and publicity including the roundel, on the Tube map, trains and stations. In 2024, it was announced that each of the Overground lines would be given distinct colours and names.
