Bakerloo line extension

The Bakerloo line extension to Camberwell is a proposed extension of the London Underground line to Camberwell in South London from its current terminus at Elephant & Castle. It was due to be built in the late 1940s, but the project was cancelled. In the 21st century the project has been revived in one version or another, but nothing has yet been agreed. Current proposals for extension of the Bakerloo line from Elephant & Castle do not always involve Camberwell. Although Camberwell is the most obvious short-range destination for a southern extension of the Bakerloo line, an extension to Camberwell seems inconsistent with many plans for longer-range extensions.
