companies' (TOCs) publicity material nor is the network being promoted by TfL. He added that whilst TfL funded the installation of Overground Network "on" signage at appropriate National Rail stations, it is being left to individual TOCs to remove these at their own expense, hence the many that remain in situ in 2008, and even some are still left as of 2021. In 2006, TfL launched London Overground, a similar but more comprehensive scheme in north London unrelated to Overground Network. Again, according to Innes Ferguson, TfL's medium-term aspiration is for the former to be expanded to cover other National Rail services in London and the South-East, either by direct TfL operation through a concession-holder (as with the ex-Silverlink routes) or by a TOC agreeing to operate under the London Overground "brand". Routes These routes were part of the scheme, and carried the on branding on station signs: Kingston Loop Line Waterloo to Teddington via Wimbledon (South West Trains) Waterloo to Reading Line Waterloo to Twickenham via Richmond (South West Trains) Sutton & Mole Valley Lines Victoria to East and West Croydon via Norbury (Southern) Greenwich Line/North Kent Line London Bridge to Dartford via Greenwich (Connex South Eastern) Additionally, these routes were shown on the network map as having 4 tph service: Waterloo to Epsom, Surbiton, Staines and Hounslow. Victoria to Epsom, Peckham Rye and Bromley South London Bridge to Crystal Palace and Smitham. Blackfriars to Streatham and East Croydon.
