The current consultation focuses on determining the level of public support for extending the line and provides an opportunity for people to comment on potential routes for the extension.
So far, TfL has identified two options for alignments and stations between Elephant & Castle and Lewisham: one service Old Kent Road and the other vis Camberwell and Peckham. Beyond this, the extension could connect with the existing rail line to Hayes. Further options could involving extending the line to Beckenham Junction or Bromley town centre.
Details of the proposals and further information are available at www.tfl.gov.uk/bakerloo-extension, where you can also leave your feedback.
The consultation will run until 7th December 2014.
