Extension to Barking Riverside It was announced as part of the 2014 United Kingdom budget that the Gospel Oak to Barking line would be extended to Barking Riverside station. £263 million was to be spent to extend the line to the brownfield 10,800-home Barking Riverside housing development, which Barking and Dagenham Council did not believe to be viable without improved transport connections.

Had this change taken place, and would no longer have had direct services to Euston station, hindering access to central London. The official Croxley Rail document states, "Bakerloo Line extension to Watford Unlikely" and "TfL’s plans to extend the Bakerloo Line to Watford Junction are on hold indefinitely due to funding and business case constraints". Croxley Link Plans were approved in 2011 for the Croxley Rail Link, diverting the Watford branch of London Underground's Metropolitan line to Watford Junction via , where it would share tracks with the Overground. However, in early 2017 this scheme was paused due to funding issues. Old Oak Common interchange A long-term plan exists to create an interchange with High Speed 2 at the proposed Old Oak Common station. Planning documents issued by the DfT suggest that the new station, on a site just south of , could open by 2025 and offer connections with the Overground on both
